Happenings and a Fermented Giveaway

Hello friends,

I hope this finds you all doing well these days.  I am making it through this especially frigid Pennsylvania winter.  I am NOT a cold weather person so these last several months of snow and plunging temperatures has not been my scene.  I’m ready for summer.  Forget springtime and the rain.  Bring on the hot temps!

I wanted to bring you up to date with a few things happening around the whole First Comes Health world.  As usual, I’ve been experimenting around the purple kitchen of mine getting a few new recipes to post (next week!).  With the seasonal changes that are (hopefully!) upon us soon, I’m getting ready to start kicking my food preservation efforts into high gear.  This means, not only am I going to be fermenting things, but pickling, dehydrating, canning, and more.  I’m getting involved in the Pittsburgh Canning Exchange this year!  I was lucky enough to be invited to their fall swap a few months ago so I could sell copies of Fermented and I told the organizers that I had to be involved in any manner possible in 2014.  I’m meeting up with them in the coming weeks and I’m really excited.

If you happen to be in the western Pennsylvania area, I’m teaching two sessions of a class on how to start fermenting at home.  Each one is hosted by Fox Chapel Area Adult Education.  They are March 25 and April 8, both at 7 pm.  Check out their website for more details!

I’m finding it very difficult to communicate with all of you, dear readers.  If you’re a regular reader of any blog out there, you’ve probably heard this familiar lament – Facebook is messing with us!  What started out as a really great way for small businesses to communicate with clients and fans has morphed into a disappointing dead end.  Boo.  I am truly grateful for all 4700 or so of you who “like” me on Facebook, but I know that only a wee percentage of you are actually seeing First Comes Health in your newsfeeds.  You can change this by making sure that “show in newsfeed” is checked when you hover over the LIKE button on this page.  It’s totally discouraging when I put something up there and see that only 71 of you have seen it.  I hope you’ll help me change this around!

I also want to remind you that there are many other ways you can keep in touch with me, know when I’m doing something, see photos of my antics (both culinary and personal), and interact.  I’m on Instagram (my favorite!), Twitter, and have a newsletter too. And in a shameless act of bribery, I’m going to give you some incentive to connect with me – a signed copy of Fermented.  I’m also trying out this Rafflecopter stuff, so please bear with me!

So, that’s about all for now.  The giveaway lasts for a week (officially ending on 12 March at midnight!), so enter and spread the word to others, please.  You have multiple chances to be successful!

Kombucha Series Part 6 - Troubleshooting (Plus a GIVEAWAY!)

This giveaway is closed.  Thanks for the entries!

Well, we have reached the end of the weekly kombucha series and I hope you all have enjoyed it. Kombucha is my favorite thing to ferment so I’ve loved writing this up for you.  Plus, I am SO EXCITED about the giveaway!  Details are at the end of this post.  You do NOT want to miss this one!

If you’re just joining me for the first time, here is what you missed:

1. Make your own SCOBY
2. Choosing the right tea
3. Choosing the right type of sugar
4. Equipment
5. Make kombucha – woo woo!

Throughout the last six weeks I have gotten a few questions about what is normal SCOBY behavior, what the tea should look like or smell like, etc.  Here are a few answers to some FAQs about your ‘buch.

1. Cloudy tea and/or brown bits in kombucha – This is good!  When you initially combine your sweetened room-temperature tea, the SCOBY, and starter tea, it is all mostly clear.  Sure, it’s retained the color of the tea that you brewed, but it isn’t cloudy.  As the SCOBY gets to work and the bacteria and yeasts do their job the tea will turn cloudy.  You may also start to see brown stringy bits floating off of your SCOBY and in your tea.  This is just yeast growth and you want it in there.  Fear not!

(Look at the stringy bits hanging off of this SCOBY.  It’s growing yeast!  WOO!)

2. SCOBY storage – The most important thing to know about properly storing your SCOBY is that is must be kept in liquid at all times.  If it won’t be hard at work fermenting any tea for a month or two, a SCOBY needs to be stored in tea and kept wet especially if they are going to be used again in the future.  If you are taking a fermentation break or find yourself with extra SCOBYs simply keep them in a small jar covered in sweetened room temperature tea.  Cover loosely with a light cloth or handkerchief secured with a rubber band.  Store at room temperature.
SCOBYs can be refrigerated or dehydrated for longer term storage, but there is not guarantee that they’ll come back to life when you’re ready to use them again.  This is why I don’t wholly recommend refrigeration or dehydration.  It isn’t a terrible idea, but nothing is guaranteed.  To dehydrate, simply put the SCOBY on a Pyrex plate or on a piece of all-natural parchment paper and allow it to dry at 90 to 100 degrees in the oven for several hours, or until it has the same texture as gummy candy or beef jerky.  For instructions on rehydrating your SCOBY, check out this video from Cultures for Health.

3. SCOBY looks and feel – A healthy SCOBY will be whitish/ivory colored.  Sometimes it will have brownish tea-colored stains on it (especially if you use black tea to ferment your kombucha), but it will never ever be black, red, green, or blue.  If you see any colors beyond white/ivory/beige and brown, this is most likely a sign of mold growth and the whole batch (SCOBY included) must be discarded.  Do not take chances, and please use your best judgement.  If you are in doubt at all over your SCOBY’s health, toss it and start over.
A healthy SCOBY should also feel like a handful of dense gelatin.  It’s wiggly and jiggly and feel kind of squishy in your hand.  It shouldn’t be dry at all.

IMG_6660

4. SCOBY size – They say size doesn’t matter, and with SCOBYs at least, that’s true.  My very first SCOBY given to me by my buddy Liz was about three or four inches across and a quarter inch thick.  She gave it to me in a little jar with a cup of starter tea.  From that wee SCOBY I brewed a gallon of kombucha and have been making batch after batch ever since.  Plus, that original mother has given birth to dozens of new SCOBYs that I’ve gifted all over the place.

5. SCOBY placement – When I started my first batch of kombucha, I dumped my SCOBY and starter tea into my gallon of sweetened room temperature tea and it promptly sunk to the bottom. I (stupidly) stuck my hand in the jar and tried to get it to float on the surface.  It didn’t work.  I had a minor freakout.  It turns out, it doesn’t matter one whit where the SCOBY is in the jar.  It will still do its job nicely.  A new SCOBY will grow on the surface of your tea (you might notice it starting to grow when you see a cloudy film start to appear.) no matter where your original mother decides to settle.

6. Metal – Kombucha, SCOBYs, and metal do not mix.  As previously mentioned in the equipment installment of this series, you should not ever ferment tea in a metal container.  Period.  Some kombucha makers say that a SCOBY should not ever ever ever come in contact with anything metal.  While I agree, I don’t happen to think that very brief encounters with metal will not hurt your brew or your SCOBY.  I brew my gallon of tea in a metal pot and I have cut sections off of SCOBYs with metal knives or kitchen shears with no ill affects yet.  Technically speaking, molecules of metal are left behind when you do these things and over time can affect fermentation.  My rule is this: Never ever ferment tea in a metal container.  Avoid using metal tools when you can. Anything that will come in prolonged contact with your SCOBY or kombucha should NOT be made of metal.  Otherwise, if you want to use a knife or kitchen scissors to snip off a bit of a SCOBY to give to a friend, just do it quickly.

7. Kombucha storage – After I flavor and bottle my ‘buch, it doesn’t tend to last very long in my house.  Honestly I haven’t ever had a bottle sitting in my refrigerator for longer than a couple of weeks.  However, as long as it is kept cold, bottled kombucha will last for a very long time.  Note, however that fermentation does not stop just because it’s in the refrigerator.  It is slowed down to an almost near halt, but not quite turned off.  Over time your kombucha will continue to ferment very slowly.  Consider this an aging process much similar to what wine goes through.  The taste of a bottle that is two weeks old will be slightly different than one that is 6 months old.  It’s up to you to decide whether or not that’s a good thing or a bad thing.  It’s a matter of taste.
Also note that a little wee miniature SCOBY may start to grow on the surface of you bottled ‘buch.  That’s just further proof that the little bacteria and yeast friends in the bottle are still fermenting away.  This mini SCOBY can be strained out and discarded or even consumed if you want.  It definitely won’t hurt you.

8. How much to drink – Like any fermented product, kombucha is alive and can do a lot of wonderful things for our bodies.  However, if a little is good, that doesn’t necessarily mean that a lot is better.  When I first started making kombucha I was guzzling several bottles of it a day.  It tastes wonderful, plus it’s fizzy. I haven’t had a pop in YEARS so it was nice to drink something cold and fizzy!  While this might have tasted good at the time, it started to negatively affect my body.  Fermented foods are meant to be enjoyed regularly, but in small quantity.  Eight ounces of kombucha a day is plenty to keep your gut populated with beneficial bacteria.  It may be difficult to resist those wonderful little bottles of ‘buch in your fridge, but overdoing it with kombucha or any fermented food will take its toll.

Kombucha Series Part 5 - Let's Make Kombucha!

This is the post you’ve been waiting for!  It’s time to take what we learned in the previous installments in this series and put it to good use!

If you need to catch up to speed here is where you can find the first four posts:

1. Make your own SCOBY
2. Choosing the right tea
3. Choosing the right type of sugar
4. Equipment

Hopefully by this point you have assembled all the stuff you’ll need to get your first batch of kombucha going strong – SCOBY, tea, sugar, and a jar at the very least.  Once you have all you need, the procedure is actually quite simple.  The hardest part is the wait!  Kombucha making – fermentation in general! – requires patience.  If you’re anything like me, you’d prefer to have your ‘buch sooner rather than later, but trust me.  This is worth the wait.

Kombucha Jars Collection2

Part 1

  • Water – Fill a large pot with enough filtered water to fill your fermentation jar almost to the top.  Leave about two or three inches of headspace (that is, empty space at the top between the tea and the very top of the jar.).  If you have a gallon jar, you’ll want a gallon of water MINUS a cup or so.  Eyeball this.  It’s not that scientific.
    By the way, I suggest filtered water because regular old tap water can contain flouride, chlorine, or other chemicals, additives, or particulates that can interfere with SCOBY growth and fermentation.  I use a water filter pitcher for my drinking water and I’m thinking of getting a really nice household sized one in the near future.  I don’t want anything in my water to negatively affect my ferments!
  • Tea –  If you are using teabags, use 6 or 8 of them.  If you are using loose tea, you’ll need about 1/3 cup of the tea leaves.  Also with loose tea you have two choices: The first is to just brew the tea by tossing the loose leaves directly into the water.  You’ll have to strain them out later before you add your SCOBY.  The second is to put the 1/3 cup of tea into a tea ball, infuser, or make a giant sachet with a coffee filter and butcher’s twine.  The choice is yours and the quality of your kombucha will not be affected by whichever path you take.  Personally, because I have many coffee filters on hand, I opt for the sachet method.
  • Sugar – You’ll need a scant cup (just a bit under a cup) of sugar for every gallon of kombucha you’re making.
  • Procedure
    1. Heat the filtered water to just shy of boiling (approximately 200 degrees).  (It’s not a big deal if it boils, but tea isn’t meant to brew in water that is at a rolling boil.)
    2. Add the tea and allow to brew for at least 5 minutes.
    3. Remove tea infuser or sachet (if using) and remove the pot from the heat.
    4. Add the scant cup of sugar and stir with a wooden spoon until completely dissolved.
    5. Leave the pot of tea on the countertop to come to room temperature. (If you used loose tea without an infuser, strain the loose leaves out of your sweetened tea after it has come to room temperature to avoid scalding yourself!)
    6. After your sweetened tea has come to room temperature (that is a VERY IMPORTANT STEP!) carefully pour it into your fermentation vessel.  Use a funnel if you are accident and spill-prone like I am.
    7. Add your SCOBY and the starter tea it is sitting in to the sweetened room temperature tea.
    8. Cover with a coffee filter or light cloth secured with a rubber band and allow to ferment at room temperature.
    9. Check on your brewing kombucha every day or so.  You should start to see a new SCOBY form on the surface of your tea.
    10. After a week or 10 days, taste test an ounce or so of your brew.  It should start to have that characteristic “fermented” tang to it.  Depending on how you prefer your kombucha to taste, it may or may not be finished at this point.  It is up to your taste buds to decide.  If you prefer a sweeter kombucha, it will require a shorter fermentation time.  If you prefer a more tart or dry kombucha, you’ll want to let it ferment a little longer.  This is up to you!  Taste test it each day or so until it suits your palate.  To give you a bit of context, in my (rather warm) home it can take 10 days to 2 weeks for my kombucha to taste the way I like it.

When your kombucha tastes right to you, you’re finished.  Congratulations! You’ve made kombucha!  Drink up!
But please don’t stop there.  You’d be missing out on a really terrific opportunity to explore your ‘buch-making artistry if you didn’t bottle it and ferment it a second time.  Read on…

Part 2

There is really no requirement that says you MUST bottle and flavor your kombucha, but to me, this is the best part of making it.  I love it plain, but I love it even more when it’s been flavored and is fizzy.  Here’s the simple lowdown on how to turn your jar of kombucha into bottles of fizzy fruity goodness.

IMG_6721

  • Fruit, juice, and herbs – Gather up the stuff you want to use to flavor your kombucha.  The possibilities are nearly endless here and now that we are in the midst of springtime here in the Northern Hemisphere, you have more and more fresh options available to you at farmers’ markets and your local grocery.  Take advantage!
    If you don’t have access to fresh fruit, use frozen.  If you want to try using pre-packaged juices, go for it.
    Here are some of my favorite (and easy!) suggestions:

    • Freshly squeezed lemon and lime juice
    • Freshly squeezed grapefruit juice
    • Fresh or candied ginger
    • Strawberries, blueberries, raspberries, or blackberries
    • Kiwi
    • Bottled mango or pear juice.
  • Procedure
    1. Get your flip-top bottles ready and fill each one with fruit, juice, herbs, or any flavor combination you’ve decided to try.  Try whole pieces of fruit, fruit purees, combinations of juice and fruit, herbs, etc. Use an ounce or two of flavoring agent for every 16 ounce bottle.  This does not call for super-precise measuring, but make sure you do not overload your bottles with fruit or juice.  A little will go a long way.
    2. Fill the bottles with your finished kombucha.  This is where a racking cane and/or funnel really comes in handy!
    3. Seal up the bottles and allow them to sit at room temperature for 3 to 5 more days.
    4. Refrigerate your bottles and enjoy your kombucha cold.  Be extremely cautious when opening a bottle of kombucha!  Contents are under pressure and it is not unheard of for a bottle to erupt like a volcano! Cover the bottle with a dishtowel before opening to keep from being sprayed with an entire bottle of kombucha.  Trust me on this one.

Important Notes

  • It’s helpful to understand a bit of elementary fermentation chemistry in order to properly manage your kombucha: The bacteria and yeasts that are in your SCOBY will eat the sugar you sweetened your tea with.  One of the byproducts of this is carbon dioxide.
    While your kombucha is fermenting in the jar that’s covered with a coffee filter or light cloth, the carbon dioxide just escapes into the atmosphere.  You might see a wayward bubble here and there in your jar, but it won’t be fizzy or effervescent.
    When you bottle your kombucha with more sugar (in the form of fruit or juice), and seal the tops to the bottles, the carbon dioxide can’t escape.  It stays in the bottle which is what makes bottled kombucha fizzy.  You’ve trapped the carbon dioxide inside and when you open it, it all rushes out.  Fizz!
  • Another byproduct of kombucha fermentation is alcohol.  If you’re a regular kombucha drinker you may have noticed that you might get a wee bit of a buzz after downing an entire bottle.  (I can’t be the only one).  There is a very small amount of alcohol in kombucha.  Here are some numbers for you:
    An average batch of kombucha will contain .5 % to 1.5 % ABV (alcohol by volume) as opposed to beer or wine which can range from 2% to 19% ABV depending on the label.  You can see that it is a very tiny amount compared to actual alcoholic beverages, but it’s in there.  If you avoid alcohol for any reason it might be wise to stay away from kombucha too.  Use your best judgement!
  • Fermentation times will vary.  Because bacteria and yeast thrive in warm temperatures, they will work faster when the weather is warmer or the temperature in your kitchen is warm.  During the winter months or when our homes are cooled by air conditioning, fermentation times can be a bit longer.  This is why you taste test to determine when your kombucha is finished fermenting to your liking.

There you have it!  The very basics of kombucha making!  I am sooooo excited for you guys to start brewing your own.  Please please please keep me updated with your progress and do not hesitate to contact me with questions.  I’m always available by leaving a comment, email, dropping me a note on Facebook, tweeting me on Twitter, or even cruising on over to Instagram.

And don’t forget to pre-order your copy of Fermented, A Four Season Approach to Paleo Probiotic Foods.  There are several very unique kombucha flavorings included in the recipe sections.  Go beyond fruit and juice and incorporate vegetables, herbs, and more into your ‘buch flavorings!

Next week is the final installment!  I’ll be covering troubleshooting and FAQ, so get your questions, comments, and problems to me ASAP!  And you do not want to miss the kombucha-related giveaway I have planned.  One of you is going to win a pretty sweet gift.  Stay tuned!

Kombucha Series Part 4 - Equipment

If you missed the first three parts, check them out here:
1. Make your own SCOBY
2. Choosing the right tea
3. Choosing the right type of sugar

I hope you’ve taken the time to read the first three installments in this kombucha series.  The previous posts will guide you through the preliminary steps necessary for top-quality ‘buch making.  This week’s post is focused on the necessary equipment needed to make kombucha.

To be completely honest, this post could be just a few sentences long.  Allow me to give you a list of all the necessary kombucha-making hardware:

1. A clean glass jar.

That’s all.  This is the beauty of fermentation – because it is such an old craft there isn’t a need for fancypants equipment and gadgetry.  If your great great great grandparents were making kombucha, chances are they didn’t have pH strips, racking canes, continuous brewing rigs, flip-top bottles, etc.  They just used what they had.

But, we live in 2013 and just because we don’t NEED all kinds of equipment for fermentation in general and kombucha making in specific, doesn’t mean that we can’t use some modern-day equipment to make our lives easier.  I mean, my forebearers didn’t have cars, but I’m using one today, right?  Conestoga wagons aren’t my style.

IMG_6625

So, below you will find a list of suggested equipment for kombucha making.  I’ll let you know which things I believe to be more useful than others (my opinions), and you can start assembling your ‘buch-making arsenal.

1. A clean glass jar – As noted above, this is probably the only piece of hardware anyone needs for kombucha making.  The size of the jar depends on how much kombucha you want to make.  For me and my household of two adults and no kids, a half gallon jar is enough for an 8-pack of flavored kombucha.  You may find that you want more or less, so adjust the size accordingly.  Just make sure the jar is food-grade glass.  Ceramic is a possibility if you know the glaze on it is food-safe (some are lead based), and metal and plastic are no-nos.  Just stick with a big glass jar and you’ll be fine.

2. Jar covering – Many jars come with lids, but don’t use them for kombucha making.  You want air to be able to get in and out of your kombucha as it ferments and closing it off with a lid just won’t do.  Instead, use a piece of cloth (clean handkerchief) or a coffee filter secured with a rubber band or string.  I do not recommend cheesecloth for this job as the holes in cheesecloth can be large enough for bugs to get in and out of your kombucha jar.  If this happens you are immediately in a throw-it-all-out-and-start-all-over-from-the-beginning scenario.  A piece of light cloth or a coffee filter are light enough to allow air to escape, but have a tight enough weave to keep any intruders at bay.

IMG_6627

3. Funnels – I find funnels to be one of the most useful kitchen tools whether or not I’m using them for fermentation.  I’m clumsy and sloppy so any gadget that keeps me from spilling and making a mess is alright in my book.  As far as kombucha making goes, you may find yourself pouring liquids from one vessel to another and funnels of various sizes come in handy.  I have two that are rather small that I bought in a kitchen supply store and one other that I use for large jobs that I picked up in an auto parts store because it is made for helping with an oil change.

4. Racking cane – When I first starting making kombucha I had never even heard of such a device.  Then I met Naomi of Red Star Kombucha and she told me about it.  She regularly makes enough kombucha to fill kegs, so her glass containers are 10 gallons or more.  That’s a lot of kombucha and a lot of HEAVY jars. It is dangerous to pick up a 10 gallon glass container and pour ‘buch out of it!  Instead she uses a racking cane.
A racking cane is a siphon of sorts that is also its own little pump. Simply put one end in the large kombucha filled container and the other in the empty vessel.  Pump the pump a few times to get the liquid flowing and voila!  You have kombucha flowing from your large jar into smaller containers in no time.
Racking canes are available at brewers’ supply stores and come in various sizes.  Many of them also come with a choke device to fit on the tube to stop the flow of liquid when necessary.
Honestly, when I’m bottling kombucha for a second ferment, I use my racking cane AND a funnel, (Like I said, I’m messy.) but the racking cane was a life saver for me.  I love mine and wouldn’t want to bottle an 8-pack without it.

racking cane

5. Flip-top bottles – In the next installment in this kombucha series I am going to cover putting it all together and actually making kombucha.  When you read that, you will see that kombucha is finished and potable before it is bottled.  Therefore, flip-top bottles are not at all essential equipment. However, I would be willing to bet that most kombucha you have ever had in your life has come in a bottle and it’s fizzy.  Flip-top bottles (or even jars with tight-fitting lids) are what help make it fizzy.  Straight out of your fermentation vessel, kombucha is not that fizzy.  Remember, you’ve covered it with something that allows air to escape so any effervescence that could have built up has now escaped.
For the time being, do not get mired down in the procedure of kombucha making.  That is for next week’s post.  But if you are interested in fizzy kombucha, flip-top bottles are what you want to have on hand.

IMG_6690

6. Mortar and pestle, food processor, blender, or mini-chopper – When it comes time to spread your creative wings and fly into the world of flavoring your kombucha, having some piece of equipment that will pulverize fruit and herbs will come in handy.  If your knife skills are up to the task, then by all means, skip these things.  I prefer my ‘buch flavored with juices and finely blended fruits.  This isn’t something I can do by hand so I let the machines do all the work for me.

7. A fine sieve – If you are anything like me, and chunky kombucha isn’t your thing, then blending fruits for ‘buch flavoring in a blender or food processor is step one in the prep, and step two is running the fruit pulp through a fine sieve.  You kombucha will be free of miniature seeds, fibers, leaves, and pulp!

8. A continuous brewing vessel – This is not at all necessary equipment for kombucha making, but it definitely falls under the category of convenience devices.  When I make kombucha, I use a half-gallon glass jar, bottle it using a racking cane and funnel, refill it with tea after that, and I’m done.  This system works for me, but the only downside is that once I bottle a batch and start another, I have to wait a few weeks before my next batch is finished.  There is some down time between when Dude and I have finished the 8 bottles and when the next batch is ready.  Like I said, this works in our household, but if you absolutely cannot live without your ‘buch from day-to-day, perhaps a continuous brewing system is what you need.
A suitable vessel for a continuous brew system is similar to what you would need in any kombucha making vessel – glass or ceramic food-grade jar.  Continuous brew vessels are typically larger (a gallon or more) and also feature a spigot near the bottom of the container.  This allows you to remove kombucha from the container without disturbing the SCOBY (which is usually found on top of the liquid).  You will regularly remove kombucha through the spigot and bottle it (or just drink it straight from the tap!), and then replace what you have removed with sweetened tea.  No need for racking canes, funnels, or waiting for the next batch to brew.

9. Various other gadgets – When you get in to bottling and flavoring kombucha, a collection of other gadgets may come in handy.  Citrus reamers, cherry pitters, strawberry hullers, ginger graters, etc.  Use these at your own discretion.  They are far from necessary!  I live in a small condo with a modest kitchen so I don’t have room for all kinds of extra stuff (or as Alton Brown would call them, unitaskers!). But I know that kitchen gadgets are popular and some of you may have these tools already in your arsenal or you just like collecting fun kitchen tools.  Power on.

A note about materials:  As mentioned in the SCOBY post, because it is a live delicate collection of beings, it is also fragile.  Harsh chemicals, cleaning agents, and certain materials are bad for kombucha making and SCOBY health.  Be sure that your vessels are all food grade glass or ceramic.  Metal and plastic have no place in kombucha making.  That is to say, anything that will come in prolonged contact with your ‘buch should not be made of metal or plastic.  Siphoning your kombucha from a jar to a bottle through a racking cane with plastic tubing or straining fruit juices through a metal sieve is perfectly fine.  But brewing a batch in a metal container or plastic jug is not.  If you are considering a kombucha continuous brew system, be sure that all of the components are food-safe and made of the proper materials – especially the spigot!

As with any hobby, kombucha making (or any kind of fermentation) can be as simple or as complicated as you want it to be.  Have a jar?  You have enough to get started.  All other equipment is optional, but as I mentioned above, there isn’t a thing wrong with injecting a little convenience into your life.  If you are just starting out, do not buy a kitchen full of equipment!  Get the basics and grow your kombucha making operation from there.

Feel free to check out my Amazon store for a listing of equipment that I use to brew kombucha and other stuff that I find indispensable in my kitchen including all the stuff I list in this post.  (Note, that this link leads to my Amazon.com affiliate store where I will earn a small percentage of moolah for each purchase you make from it.  Just FYI.)

Stay tuned for next week’s post when we put it all together!  SCOBY + tea + sugar + equipment = KOMBUCHA!  At last!

And as usual, if you have any questions, comments, or issues you’d like me to cover in upcoming installments, leave me a comment, catch me on Facebook, send me an email, or tweet me a Tweet.

Kombucha Series Part 3 - Choosing Sugar

Are all strapped in and ready for part three in my kombucha series?  I sure hope so.

In case you missed the previous hoopla:
Part 1 focused on making your own SCOBY from scratch.
Part 2 was all about choosing the right tea for successful kombucha brewing.

If you’ve been following along so far, you are well on your way to successful home kombucha making.  Your SCOBY should be in fine shape and hopefully you have some tea on hand that will eventually be turned in to some delicious ‘buch.  Before you get started, however, there is one final element needed to get the fermentation ball rolling.

Fuel.

That SCOBY you now have is a bundle of living creatures whose very nature it is to eat and procreate.  Now, you won’t have to put on any Barry White music to encourage those little bacteria yeasts to make wee babies, but you will have to provide them with food to eat to fuel their reproductive efforts.  That is where the sugar comes in to play.

Right about now I anticipate a comment like this:  “But!!!  But!!!  But!!!! Isn’t sugar BAD for you?!?!?!”

Yes.  It isn’t called the white devil for nothing.  HOWEVER!  We’re talking fuel here.  We aren’t talking about added sugar to be consumed by the teaspoonful.  We aren’t even talking about making something that is even considered “sugary”. The bacteria and yeast need food to eat so they can proliferate and therefore ferment our tea into ‘buch.  By the time it is all said and done, there will be far less sugar in a bottle of ready-to-drink kombucha than there was when you started brewing it.  My point is, do not freak out over the use of sugar.  It’s a necessary part of the process.

The deal with sugar is this: There are almost as many kinds on the market as there are types of tea.  What to use?

Let’s first talk about what all of those sugars are, how they’re made, what their individual merits are.  Then we’ll move along to a recommendation or two.

Sugar comes from one of a few sources – sugar cane, sugar beets, a beehive (honey), leaves (stevia), various grains (corn syrup, rice sugar), and even sap from various plants (coconut sugar, agave nectar, maple syrup, etc.)  Generally speaking the raw materials are harvested, refined in some way by removing impurities, and then packaged for sale and consumption.  That is REALLY watering down the process, but for what we are covering here, the exact tedious and history-rich process is not important.

Sugars

  • White sugar – The ubiquitous white sugar is very processed sugar cane (or sometime sugar beets) that has all impurities, molasses, and excess water removed from it.  It is usually sold in five-pound bricks in any supermarket.
  • Raw sugar – Although calling raw sugar “raw” is a bit misleading, it is not as processed and manipulated as its cousin, white sugar. When sugar cane or beets are processed into table sugar, they go through several steps of refinement. The original crop is chopped, crushed, and essentially juiced of all the liquid inside. That liquid is boiled to concentrate it and the resulting product is molasses and molasses-rich raw sugar crystals. Further refinement of these crystals extracts more molasses and turns the crystals white and into the common white table sugar. The reason that raw sugar has a light brown color is because it is only partially processed and molasses has not been completely removed.
    Other names that raw sugar is sold under include turbinado sugar, demerara sugar, and the brand name Sugar in the Raw.
  • Barbados or Muscovado sugar – This is a type of sugar found very commonly in the United Kingdom and has a very high molasses content. The sugar crystals are a bit larger than one would expect from standard white table sugar, and the texture is slightly sticky. Elsewhere in the world, Barbados or Muscovado sugar is called Panela sugar or Rapadura.

  • Brown sugar – Unlike raw sugar or Barbados sugar which are indeed brown, brown sugar, the kind commonly used in baking, is not actually partially processed sugar. Instead, it is processed white sugar that has molasses added back into it to give it a brown color, sticky texture, and the ability to be packed like wet sand.
  • Cane juice – Cane juice is another name for the liquid that is yielded in the preliminary steps of sugar processing when sugar cane is mulched into small pieces. The resulting liquid can be bottled and used directly as a sweetener and is sold as cane juice.
  • Evaporated cane juice – It is exactly what it sounds like. The cane juice, which is a product of grinding up sugar cane, is heated and the water content evaporated leaving sugar crystals behind. Evaporated cane juice is often sold under the brand name, Sucanat.

There are several other types of sugars and sweeteners out there, but they are not at all recommended for kombucha making.  This list of no-nos include honey (unless pasteurized), molasses, stevia (leaves or liquid), agave nectar, coconut sugar, rice sugar, corn syrup, high fructose corn syrup, maple syrup, or any artificial sweetener like aspartame, saccharine, xylitol, etc.

So, given the list of acceptable sugars, which one do I highly recommend?  The answer might surprise you!  Plain old, highly-processed, inexpensive white sugar.

Because it is just about pure sucrose, there is really nothing in it that will interfere with SCOBY growth and development, taint your kombucha with a molasses flavor, or discolor it in any way.  It has the right chemical compound in the right proportion that is easily accessible to the bacteria and yeast that will fuel the SCOBY’s fermentation power.

A drawback to white sugar is that it is difficult to find organic white sugar.  In the previous installment I was adamant about using organic tea to make kombucha because you just don’t know what else is on the tea leaves when they’re not organically grown and handled.  The same is true for sugar. Do you know what they put on sugarcane or sugar beet fields to keep pests at bay and to facilitate crop growth?  Me either, but it’s typically chemical laden garbage that ends up in your food and there for in your body.  Blah.  Chemicals and fertilizers and pesticides do not make good SCOBY food either.

Also, if you are avoiding GMO goods, white sugar made from GMO beets are an obvious do not use product.

So, what to do?  Truthfully, I grit my teeth and use regular white sugar anyway.  On the off day that I can find organic white sugar, I buy some and use it happily.  But most other times, I just use the conventional white sugar made from cane.

(Yeah, this is a Lionel Richie cream and sugar set.  Wanna fight about it?)

A few words about how much sugar to use
In upcoming installments, I will share my kombucha recipe with you.  It will contain proportions and measurements for each ingredient.  Please do NOT skimp on the amount of sugar called for.  Remember, it is in the recipe because it is SCOBY food/fuel.  It is a very important part of the yummy chemical experiment you will be conducting in your kitchen.  I know that as a healthy eater it seems almost counter-intuitive to use heaps and heaps and cups and cups of sugar, but trust me on this one.  You will be rewarded with a healthy SCOBY and delicious fizzy kombucha.

Ok!  That’s all for this week.  Please let me know if you have any questions, problems, or concerns.  I want to hear from you!  Email me, contact me via Facebook, Twitter, or in the comments below.  And heck you can even find me on Instagram.  Tell me about your own kombucha experiences or what you would like to experiment with in the first place.
And don’t forget that these kombucha posts will be a weekly occurrence for a while so if you have issues, questions, or topic suggestion for future weeks, tell me in the comments or through one of my aforementioned social media outlets and I’ll do my best to address it.

Kombucha Series Part 2 - Choosing Tea

In case you missed Part 1 about making your own SCOBY from scratch, check it out here.

Let’s move right along with dissecting the art of kombucha making by getting to the very essence of what it is all about – tea.  Kombucha is fermented tea, of course, so without it we have a whole lot of nothing.

There are approximately a million and one teas on the market (scientific counting method!) and the range in quality from artisan fancypants teas that bloom a flower in your cup to disgusting little paper bags of tea dust that was swept up off the floor of a teabag factory.  There are teas that make you sleepy, pep you up, settle an upset stomach, and one that are supposed to make you do a number 2.  It is almost overwhelming how many teas there are in the average supermarket aisle.

Teas

What Is Tea?

When you break it down there are only a few kinds and styles of tea.  True tea comes from the leaves and buds of the plant, camellia sinensis. Without getting too complicated or too scientific or muddy the waters with details that aren’t essential to kombucha making, there are four types of camellia sinensis and they come from different regions of the world.  Do not worry about these finer details, however.  For the purposes of casual kombucha making we’re just going to talk about camellia sinensis in a general way and leave it at that.

Ok, so camellia sinensis is the actual true tea that you think of when you think of tea as a beverage.  Generally speaking, after the leaves and buds are harvested from the plant, they are dried and oxidized and possibly subjected to a whole host of physical treatments in order to bring out the certain flavors. This one kind of leaf goes through different processes depending on what the desired outcome is.  Look at this table to see the different ways leaves are handled to produce various types of tea:

Let’s focus on the most common types of tea; the ones you are most likely to find in your local market or from your favorite tea purveyor.

Types of Tea

  • Black tea -Black tea is the most common type of tea produced in the world.  It is what is found in the most common and most inexpensive teabags that are widely available in every restaurant and supermarket in the western hemisphere.  As you can tell from the table above, black and oolong teas are the most “processed of all the teas because they go through the most handling before they are finished. Black teas are the most popular choice for kombucha making.  It offers a nice flavor and is widely available.
  • Green tea – Another popular tea and often touted for its health benefits, green tea is still made from camellia sinensis, but once the leaves are picked it goes through a vastly different series of processes than its black tea cousin does.  Green tea tends to be a bit milder in flavor and have grassy notes whereas black tea can be almost woody, fruity or even smoky.  Green tea makes excellent kombucha and personally speaking it is my tea of choice when I brew my ‘buch.
  • Oolong tea – This is a compromise tea between black and green.  It is processed in much the same way as black tea, but the oxidation session is not as long.  The tea’s flavor profile sits between fresh/grassy/light and woody/robust/strong.  Oolong teas can be found in supermarkets, however, they are overshadowed by the overwhelming number of black and green varieties.  Kombucha made from oolong tea is terrific.
  • White tea – While still coming from camellia sinensis and still subjected to a few processes before it is ready for brewing, white tea is made from immature leaves and buds.  If you are brewing white tea to drink hot or iced, it is a fantastic light tea.  For kombucha making, however, it is not the strongest choice.  There are chemical compounds that are present in mature tea leaves that are needed to successfully brew kombucha.  Because white tea has not fully matured, it is a bit more difficult to make a batch of ‘buch with it.
  • Rooibos tea – The one exception to the rule!  Technically rooibos (pronounced ROY-bus) tea is a type of herbal tea and is not made from our friend camellia sinensis, but rather made from aspalathus linearis, which is native to South Africa.  Rooibos teas are generally sweet and grassy or sometimes smoky and naturally caffeine free.  Also commonly known as red tea, rooibos teas make really good kombucha especially for those wanting to avoid caffeine.
  • Herbal tea – While extremely delicious and flavorful, herbal teas are not really teas (that is, they often do not contain any measure of camellia sinensis) and therefore cannot be brewed into kombucha.  Sometimes called “herbal infusions” because technically they don’t contain any tea, this type of tea simply does not have the stuff needed to make kombucha. There are some herbal teas on the market that are blends of herbs AND genuine tea leaves, but they just aren’t quite strong enough to ferment properly.  If you are looking to flavor your tea with herbs, I recommend doing so after the kombucha has fermented (this will be covered in future posts!)
  • Flavored tea –  This type of tea is not recommended at all for kombucha making.  While flavored teas are typically black, green, rooibos, or oolong teas, teh artificial agents used to give the tea a specific fruity or herby flavor can interfere with SCOBY growth and development.  There are kombucha-friendly teas commercially available that contain dried fruit and herbal extract, and these can make wonderful ferments, but if a tea is merely coated in artificial flavorings, steer clear.

Ok, so now you’ve settled on a black tea, green tea, oolong tea, or rooibos tea.  Now what?

Details

  • Organic or Conventional – Because you are cultivating a living, growing creature during your ferment (your SCOBY), you want to make sure that you are giving it the best, most optimal environment in which to grow.  This is why I choose to use organic teas when I make kombucha.  There is no telling what in the world is sprayed on to your leaves while they are still in the field, and because they go through some heavy processing to become brewable you want to make certain that the whole system is as natural and as clean as can be.  Spend the extra money and get organic tea.  Your SCOBY will thank you for it, and you will have a better final product when you’re sipping your ‘buch at the end of the process.  Verdict: organic all the way.
  • Tea bags or loose tea – There are many reputable companies out there that sell top-quality teas in teabags.  It would be incorrect to say that you cannot find a decent tea in a teabag.  It simply isn’t so.  However, it is really very easy for a tea purveyor to hide tea dust poor quality tea inside a bag.  Caveat emptor! Teabags do not equal bad tea, but you have to do your due diligence and find out if you are getting a good product.  Rip open a bag and see what the leaves look like.  Do they actually look like leaves or are they shards of leaves and dust?  Remember, tea comes from a plant and it ought to look similar to its original form.
    Obviously loose teas cannot hide in a bag and you can very easily see, smell, taste, and feel what you are buying.  Their only drawback is figuring out how to brew a large quantity (a gallon or more) of loose tea, but we’ll get to that in a future post.  Verdict: It depends.  Good kombucha is made from good products so if you find a quality bagged tea, use it.  Loose teas are often less expensive per pound, plus their quality is readily visible.  What really matters is that you are using the best tea you can afford whether it comes in a bag or not.

IMG_6669

  • And now here is the part where I will go against everything I just said – Yes, you can buy inexpensive store brand teabags full of cheap tea and make kombucha out of it.  It will work and the tea will ferment.  It might even taste just fine.  However, I strongly encourage you to go for quality on this.  Get the finest tea your budget will allow because the quality of what you are making hinges upon it.  Sub-par ingredients yield a sub-par final product.  Quality matters.

Where to Buy?

  • Supermarket or co-op – Your local market probably has an enormous tea section.  Most places do.  If you belong to a food co-op you may even have a section where loose teas are sold in bulk.  Before buying anything, be sure your choice contains camellia sinensis, or it isn’t tea and won’t ferment into kombucha.  (Unless it’s rooibos, but see above for that exception.)
  • Asian or Indian markets – Because tea is widely grown in China, India, and Japan (among many other areas), some really unique and delicious teas are available at Asian or Indian markets.
  • A coffee and tea specialty shop – If you happen to live in a larger metropolitan area, then chances are you have a gourmet coffee and tea purveyor nearby.  You will find teas imported from all over the world in shops like this (often sold in bulk), and if you get to know the owners and buyers for these places, you can get some serious education about their coffees and teas.  Plus they’re often locally owned so not only will you get some terrific tea, but you’ll support your neighbors too.  Win-win.
  • The Internet – Research, research, research.  And then buy teas online.  Be sure you are getting what you pay for.

The Take Home

In a quick little nutshell, here is what you need to know about tea selection for kombucha making:

  • Viable tea candidates – black, green, oolong, rooibos
  • Buy organic
  • Loose or teabags, but be sure what you are buying is top-quality tea
  • Available nearly anywhere – mainstream supermarkets, food co-ops, Asian or Indian markets, coffee/tea purveyors, online

Kombucha Series Part 1 - Make Your Own SCOBY

A few days ago I mentioned on Facebook that I get a lot of questions about various aspects of kombucha making.  First of all, keep them coming.  I love getting questions!  Secondly, kombucha is one of my very favorite things in the whole world so talking about it and answering questions about it makes me happy.

Many of the questions I get are from first-timers who want to start fermenting tea into kombucha and yet do not have the very basic materials to start and/or are hesitant about the procedure, troubleshooting, etc.

Kombucha SCOBY

Well, short of saying, “Wait until August 6 and BUY MY BOOK!”, I’ve decided to put together a few posts about the kombucha making process and hopefully answer some common questions around the procedure.

Today’s topic: Make your own SCOBY.

As mentioned in previous posts, a SCOBY is a gelatinous glob of bacteria and yeast needed to ferment tea.  In fact, SCOBY stands for symbiotic culture of bacteria and yeast.  It is necessary to have one in order to turn tea into kombucha.

IMG_6660

SCOBYs are not hard to come by if you have a friend who makes kombucha.  Each batch of ‘buch creates a new SCOBY and if your friend is a prolific kombucha brewer then chances are that he/she is overrun with SCOBYs and will gladly give you one along with some starter tea in order to get your new batch going.

However, if you don’t know anyone who brews ‘buch and you still want to give it a go, you will find yourself wondering just how to begin without this essential piece of equipment.  Fortunately there are other resources for you to turn to.

As weird as it may sound, you can sometimes find a SCOBY for sale (or for free!) on Craigslist.  Give it a shot.  You can also order a SCOBY from a reputable online source like Cultures for Health or Kombucha Kamp.  But if you’re like me and you’re cheap and like to save money wherever you can, making a SCOBY at home from scratch is quite easy.  It takes a little bit of forethought, a few materials, and time.

Materials needed:

  • A few cups of raw kombucha – I have always used store-bought, but I have read that using commercially bottled kombucha has an additive that inhibits SCOBY growth.  Personally I have had much success using store-bought, but your mileage may vary.  Also, I use plain (not flavored) kombucha when I grow a SCOBY.  For no reason other than if I am going to buy flavored kombucha, I’ll probably want to drink it.  Plain is plenty tasty, but I love flavored ‘buch.  Plain kombucha has fewer things added to it, obviously, so it makes it a logical choice for me.
  • A few cups of strongly brewed tea – Do not use herbal tea for this.  You must use real, honest to goodness camellia sinensis for this – more commonly known as black tea or green tea.
  • A few tablespoons of sugar – I use regular old white sugar, but you can use evaporated cane juice (Sucanat), or raw sugar.  Do not use powdered sugar, honey, stevia, or any kind of artificial sweetener.
  • A glass jar – Large enough to hold 2 or 3 cups of liquid.
  • A cloth or coffee filter to cover the jar and a rubber band to secure it.

Procedure:

  • Brew the tea using the traditional method.  When it is still hot or warm, stir in the sugar until it dissolves.  I use a tablespoon of white sugar per cup of tea.
  • Set the sweetened tea aside on the counter until it comes to room temperature.
  • Pour the room temperature sweetened tea into the glass jar and add the raw kombucha to it.  Lightly stir.
  • Cover the jar with the cloth or coffee filter and secure it with a rubber band. This allows air to flow in and out of the jar, but will keep bugs and critters out.
  • Allow the jar to sit at room temperature for several days, or up to two weeks.  During this time, a SCOBY will grow in the jar.  It will start out as a thin, milky film on the surface of the liquid and get whiter and thicker as days pass.

Notes and Troubleshooting:

  • As you can tell by the equipment and ingredients list, measurements do not have to be exact.  A few cups of room temperature sweetened tea plus a cup or two of kombucha is about as precise as you need to be.
  • The amount of time it will take a SCOBY to grow depends on the ambient temperature of your house.  Fermentation, generally speaking, goes more rapidly in warmer temperatures than in cooler temperatures.  My place, for example, is generally very warm and things ferment and grow rapidly in my kitchen.  However, my parents’ house is usually very cool and ferments take a bit longer there.
  • There are no hard and fast rules about how thick a SCOBY has to be in order to be fit for kombucha making; however, I allow my SCOBYs to grow to between a quarter inch and a half inch thick before I use them for fermentation – this can take a couple of weeks.  The only reason I have to doing this is because at that point it is solid enough to handle and I know that the bacteria and yeasts are robust and healthy after a few weeks.

IMG_6662

  • Do not discard the liquid the SCOBY grew in!  This is the starter tea you will need to use when making your first batch of kombucha.  It is full of bacteria and yeast and will keep your SCOBY hydrated and well fed.
  • If you see brown thread-like things floating in your tea or growing off of your SCOBY, do not worry.  This is good!  Little yeasty goodness that will help make your first batch of buch healthy and full of probiotic goodness.
  • Kombucha and SCOBYs smell like feet.  Do not be alarmed.
  • Mold, insect eggs, rancid garbage-like smells mean that something went wrong.  Discard the whole enterprise and start over from scratch.  DO NOT USE!
  • If nothing grows after a week or so, start over using a different kind of kombucha to start.  Get a cup off a friend, or try a different store-bought brand.  As mentioned above, I have never had a problem making my own SCOBYs from store-bought, but you may run into a snag.
