What is in Your Kombucha?

What is in Your Kombucha?

Kombucha is a pretty mysterious fermented probiotic drink.  After all, the composition and ingredients of each batch are always slightly (or a lot) different from the next, depending on several factors: the length of time of the ferment, the size of the SCOBY (Symbiotic Culture of Bacteria and Yeast), the type and strength of tea, whether or not there was a 2nd ferment, the type of sugar used, and on and on!  

The SCOBY is what mainly determines the types of probiotics found in your kombucha.  In a nutshell, the SCOBY contains several strains of yeast and bacteria that live together in harmony.  They are symbiotic, which means they depend upon each other to live.  It's actually a pretty great little community!  The SCOBY will continue to grow as long as all the proper conditions are met...and they can get pretty large! 

What is in the SCOBY and the Kombucha Tea?


Because of the fermentation process, there are trace amounts of alcohol in most kombuchas.  Generally, this amount is extremely small, less than 0.5 % alcohol.  If the amount of alcohol is over this limit, the federal government requires labeling to inform consumers of the alcohol content.  Some kombucha teas, however, have been found to have a much higher percentage of alcohol.  I personally have never experienced any problems with any kombucha having too great an alcohol content---one enough to affect me.  However, people with alcohol sensitivities should probably take some care.  


The sugar that is used to ferment the kombucha is consumed by the SCOBY, for the most part.  However, depending on the length of time of fermentation, the SCOBY may not have had time to consume all the sugar if it is a shorter ferment.  Or, some people just like their kombucha a little sweeter--in that case, yes, there will be sugar in the kombucha.  Hannah Crum of Kombucha Camp states that there is generally about 2 to 6 grams of sugar in an unflavored 8 ounce glass of kombucha.  To compare, there is about 24 grams of sugar in a glass of orange juice.  

I like longer ferments for my kombucha, so they tend to be more tart than sweet.  In my opinion, I'm not that concerned with the sugar content.  In addition, the creators of the Whole30 lifestyle plan, which is modeled after the paleo diet, state that kombucha is one of the drinks that are fine to have on the plan...and added sugar is NOT allowed on this plan whatsoever.  


Yes, it is very possible for kombucha to contain a bit of caffeine.  It will not be nearly as great as coffee, and most people will probably feel no effects.  However, again, if you are sensitive to caffeine, you can make your kombucha with decaffeinated teas.  The base of most kombucha tea is from Camellia sinensis, out of which White Tea (the least caffeinated), Green Tea, Oolong Tea, and finally Black Tea (the most caffeinated) originate. 

Bacteria and Yeast Strains

This is my favorite part of kombucha!  These strains of yeast and bacteria are what cause kombucha to be so good for you!  They are what cause the unique fermentation process! There are different strains in different cultures of SCOBY...they will not always be the same.  It depends on the environment and where you got your SCOBY: if it is a "wild fermentation," if you obtained one from a friend, if you "grew" one from some starter liquid, or the lab if it is culture that has been "created."  

The strains of yeast and bacteria are what causes kombucha to have its special flavor and also what causes the fizzing in the fermentation process.  Yes, those bubbles are good to see! These strains of yeast and bacteria are what helps to heal our guts and provide many other health benefits---more on that in another article.  

Here are some of the possible strains that may be found in your kombucha:

Acetobacter: This is always found in kombucha, and it is what builds the SCOBY.  Acetic acid and gluconic acid are produced by this bacteria. 

Saccharomyces These are yeast strains of which one or more can be found in your kombucha.  They are responsible for the creation of alcohol and yeast.  

Brettanomyces is another yeast strain that also produces alcohol or acetic acid.  (Acetic acid is what is in your apple cider vinegar!)

Lactobacillus: Produces lactic acid and slime.  Although it is fairly common in kombucha, it is not always present. 

Pediococcus: Also create lactic acid and slime. Like lactobacillus, they may or may not be in your kombucha. 

Gluconacetobacter kombuchae:  This little bacteria is only found in kombucha.  It produces acetic and gluconic acids, plus it helps build the SCOBY. 

Zygosaccharomyces kombuchaensis:  This is a yeast strain, also unique to kombucha.  It helps carbonate and fizz your kombucha as well as helps out the body of the SCOBY. 

There are probably other contributors to the kombucha process or microscopic organisms found in kombucha, but the above lists are the most common.  Acetic acid, gluconic acid, and fructose are always present, in addition to slight amounts of sugars, possibly caffeine, and varying but small amounts of alcohol.  

I have grown to love the taste of kombucha, and now that I'm experimenting with 2nd ferments, the choices of flavors and health benefits from adding herbs are endless!  I feel the health benefits far outweigh the small amounts of sugar, alcohol, and caffeine.  But that is just me.  Have you tried experimenting with kombucha?

I love this book! My mom went to the Mother Earth News Fair recently and saw Hannah Crum speak.  My mom is now a kombucha maker and drinker! She bought me this book, and I am so glad I did!  It's filled with information for all levels of kombucha fermenters!  

The kit below is GREAT if you are a beginning fermenter.  This is an affiliate link, and as such, if you click on the link and happen to make a purchase of any type, I will receive a small commission.  This allows me to continue blogging!  Thank you for supporting Healing Harvest Homestead!
