The seven biggest kombucha myths regarding this healthful, traditional beverage which are costing consumers money or scaring them away from trying it and experiencing its many benefits.
I first started brewing the fermented tea known as kombucha in 2001 when I was pregnant with my second child. It’s a good thing I ignored the kombucha myths that were circulating at the time else I never would have tried it at all!
Sipping small amounts on a daily basis proved very helpful in relieving some of the hip and low back pain I was experiencing at the time. So much healthier (and tastier!) than popping a couple of ibuprofen or Tylenol, wouldn’t you agree?
Since then, this traditional beverage that likely has its roots in China around 200 BC has become a modern-day phenomenon with well over a million homes regularly brewing this probiotic and enzyme-rich beverage for the benefit of themselves and their families.
In response to the boom in kombucha home brewing, dozens of bottled commercial brands are now available for purchase at farmers’ markets, healthfood stores, food co-ops, and even supermarkets. Having these commercial versions readily available when out of town has made healthy traveling so much easier, don’t you think?
As with any fast-growing trend, a number of myths have continued to circulate with new ones cropping up too. While some of these kombucha myths are harmless, some are actually costing people money (for example, cultures that don’t work) or discouraging them from trying this healthful beverage altogether. This is a shame and completely unnecessary, which is why I thought an article busting the most common kombucha myths would be helpful.
This list of the most common myths below was reproduced with permission from the sensational Big Book of Kombucha by my friends Hannah Crum and Alex LaGory. I have watched Hannah and Alex painstakingly and lovingly put this book together over the past couple of years, and I can tell you, they have put everything they have into it in order to create a world renowned resource for years to come.
I am not exaggerating when I say that this book is a must for your cookbook shelf. It contains literally everything you ever wanted or needed to know about kombucha, SCOBYs, brewing, flavoring, and just enjoying the myriad of health benefits of consuming fermented tea. In addition to all the fascinating as well as practical information, numerous recipes for flavorful and medicinal variations of both brewed and bottled booch are included along with gorgeous pictures to inspire you
I hope you are able to pick up a copy for yourself or as a gift soon!
Kombucha Myths Busting
* Reproduced with the permission of Storey Publishing from The Big Book of Kombucha by Hannah Crum and Alex LaGory.
The fairly recent resurgence of interest in traditional methods of food cultivation and preparation and the attendant fascination with fermenting and brewing make kombucha nearly irresistible. When ignorance and excitement combine, however, factual information often becomes jumbled with the fantastical and the fearful. As knowledge of kombucha has grown and more information has become available, old myths have been outgrown but unfortunately not always discarded.
While mostly harmless, misinformation masquerading as fact too often confuses the homebrewer and disrupts proper brewing techniques. Here are some kombucha myths we’d like to bust for good.
Kombucha Is a Mushroom
This widely held belief most likely arises from the obvious resemblance of the SCOBY to a large mushroom cap. The kombucha culture, as you know by now, is in fact a symbiotic culture of bacteria and yeast. Although the taxonomy for kombucha has not yet been formalized, mushrooms are fungi and so are yeast, so in that regard kombucha cultures and mushrooms are in the same family. But they are distant cousins, not siblings.
Adding to the confusion is that some of the old names in other languages called it a “mushroom.” When those terms were translated into English, “kombucha mushroom” became a catchy name for the culture.
Metal Will “Kill” Kombucha
Due to kombucha’s powerful detoxifying properties, dire warnings to avoid even a few seconds of metal-to-kombucha contact are overblown. Brief contact with something like a strainer or a pair of scissors will not lead to a toxic SCOBY or tainted brew. However, kombucha really should not be brewed in anything but glass. Brewing in stainless steel bowls is a risk for leeching carcinogenic nickel into the brew.
SCOBYs Should Be Refrigerated
This nasty nugget is widespread and often passed along by well-meaning brewers with the explanation, “So they won’t rot” or “It just puts them to sleep.” In fact, SCOBYs never “go bad” when properly stored. In cold temperatures the bacteria and yeast, which keep the SCOBY healthy and protect the brew, become inactive and are unable to put up a defense against mold. When a SCOBY that has been refrigerated is activated, the first batch or two may (or may not) turn out okay, but eventually, mold is likely to appear in the brew. (See page 157 for more about refrigerated cultures.)
Dehydrated SCOBYs Are Viable
The issues are the same as with refrigeration; only this time the bacteria and yeast are too weak from dehydration to protect against mold. If the culture is deprived of the protective pH of the starter liquid, which kills harmful organisms on contact, it becomes vulnerable to mold, and the bacteria in kombucha do not perform well after dehydration. Additionally, it can take up to six weeks to rehydrate a dried-out culture before attempting the first batch. No point in wasting the time for a likely-to-fail experience.
Kombucha Makes the Body Acidic
The body is a complex and marvelous organism, masterful at maintaining health through homeostasis. Significant shifts of internal pH indicate illness or, rarely, impending death. In order to maintain the correct pH at all times, our bodies employ several detoxification and buffering systems — such as the lungs, kidneys, and digestive system — to process acidic ash, the residue generated by the consumption of certain foods and also present in the body as the by-product of metabolic processes.
There is a debate over whether so-called acid/alkaline diets are beneficial to health, but we do know that when food is digested in the gut, its components leave residues that are either acid-forming or alkali forming. The body suffers from ill effects at either extreme, so the key, according to proponents of these diets, is to strive for balance rather than focusing on consuming only one type of food or another.
So what about drinking kombucha? Won’t the low pH make the body more acidic (something you’ve probably been told to avoid)? The answer is no. While it is true that kombucha has a low pH (2.5–3.5), the residue (ash) is alkaline-forming rather than acidic, and has an effect similar to lemon juice and apple cider vinegar.
Brewing Kombucha at Home Is Unsafe
When brewing kombucha at home, you pretty much have only one major issue to worry about: mold. And mold is obvious — it’s the blue, black, or white fuzz growing on top of the culture. If you see it, simply toss the brew, just like you would a moldy piece of bread, cheese, or fruit. Otherwise, if you have a quality culture and strong starter liquid, and you follow the proper procedures, success is virtually guaranteed.
Kombucha Is a Cure-All
Let’s get this straight once and for all: Kombucha is not a panacea. In fact, it doesn’t cure anything! Kombucha gradually detoxifies the body so that the immune system can function properly. Think of it as a filter cleaner, where the filter is your liver. Kombucha is an adaptogen. Adaptogens are plants or compounds that satisfy three important criteria — they are nontoxic, they are nonspecific (they work on the whole body, rather than a particular part or system), and they help the body maintain homeostasis. This means that if you need to lose weight, kombucha may help you to do so, and if you need to gain weight, kombucha may help with that also.
Have any of these kombucha myths cost you money or kept you from trying it for yourself before? If so, now you know the facts straight from Hannah Crum, the Kombucha Mamma herself!

Would you speak to the alcohol content of store bought brands?
If I make a home brew what’s to guarantee that I won’t make it alcoholic?
I do not consume alcoholic beverages.
I have never made kombucha.
Mainly I am intimidated by it. I did see a demo on how to make it once.

I have thought of trying kombucha but am using water kiefer and milk kiefer which is more work?
Juanita
I make all three and I would say one is more work than the other. They are all rather simple to maintain if you set aside a little time to supply them with fresh food on a regular basis.
Cheryl
I have made and enjoyed kombucha in the past. However after reading the linked scientific research where over 100 samples were tested and analyzed I have stopped. They found that the sugar and caffiene are NOT eaten away and it does not contain as many healthy things in it as most believe. I wonder if the authors of this book used any scientific data? If you want to stop all sugar please be aware. phoenixhelix.com/2013/03/25/kombucha-myths-vs-truths/

Really ? . I just finish my own Scoby,. now I don’t know

I tried kombucha for the first time a few weeks ago. It was delicious, but after a day or two of drinking a glass, my tongue started to hurt and feel dry. I suspected it was from the kombucha, as it was the only thing I was doing differently. Sure enough a few days after I stopped drinking it, my tongue problem disappeared. Could this be from the acid, or maybe the specific type? It was a green tea kombucha with hibiscus.
Margaret
The second myth is absolutely not true. I have heard this often on FB Kombucha sites that it is dangerous to refrigerate SCOBY’s. I have been making 6 + gallons of K for probably 12 years now. I keep my hotel in the refrigerator because i do not need to feed it. I have NEVER had mold. And yet I hear all the time of those who do not keep it in the ref. constantly fighting it! I don’t understand.

Sarah, you wrote a post a while back about fluoride in tea that gets into kombucha…do you want to direct people to that, since it seems to make a big difference what kind of tea you use and how you brew? I’ve tried kombucha a number of times but just can’t get into the taste. I love my water kefir and drink it more sour than anyone else can stand (some batches could be mistaken for vinegar….), but somehow just can’t get into the kombucha.
Sarah
Good idea … here’s the article. https://www.thehealthyhomeeconomist.com/fluoride-in-kombucha-should-you-be-concerned/
I have seen some research that these bottled kombuchas on the market are VERY high in fluoride (some of them not all!). And so be careful as I am concerned these companies are either brewing the tea far too long and/or using old tea leaves (which are much higher in fluoride than young tea leaves such as white tea) or else they are using fluoridated water.

What about kombucha eroding tooth enamel–especially in kids? Is that a myth? That’s the one I have heard before and it always makes me leery of giving my kids to much.
Sarah
Too much could be a problem, but sensible amounts are not a problem. My children have been drinking kombucha for many years without a problem as have I (and my husband).
Kenny
Thank you for all the information about Kombucha Sarah. Very interesting indeed.
Can you please comment on how much kombucha is safe to drink on a daily basis (for adults and children)? And in regards to glucuronic acid (a beneficial byproduct sometimes found in the brew and one that the body also produces), could it be the case that consuming kombucha could cause the body to produce less or stop glucuronic acid production altogether?
Sarah Pope
There are no hard and fast rules on how much kombucha is ok for adults and kids that I’ve seen. I limit myself to about 12 oz per day and would never go over 16 oz. Some days I don’t drink any. My kids were allowed only a few ounces until they were tweens and older and now they can have a small glass (no more than 8 oz) in a day. It’s really up to you … be wise and don’t overdo as too much of anything is not a good idea in most cases even when that “thing” is healthy. One lady emailed me recently that she drank 2-3 bottles of GT Kombucha every day and asked if that was too much. I said that yes, I thought it was especially if the bottles are the flavored kind with a lot of sugar. Use your common sense and don’t make something that is healthy an addictive experience like is so common in our culture.
With regard to the glucuronic acid, I wouldn’t be concerned about that as there isn’t any evidence that it shuts anything down biologically. Eating raw food full of enzymes doesn’t shut down the enzyme making process of the body, right?
Josella
Thanks for another great post. I love and follow your posts and videos. Also, you look so healthy and young in the picture accompanying this Kombucha post. Your health info since you yourself follows it must lead to health and beauty, and this outward healthy look confirms that it is the way to vitality.
Sarah
Thank you … that is very kind of you to say 🙂
Melissa
How long does a mason jar of brewed kombucha (without the scoby) last in the fridge? I have some cranberry kombucha purchased from miller organic farm a few months ago and we just never drank it.
Sarah
I’m sure it’s fine … possibly too strong to drink though. You might need to dilute it with water a bit.
