Kombucha: The Best and Worst Brands

The kombucha craze is sweeping across the world and new brands are popping up left and right.

It’s comparable to what has happened with the craft beer industry. More and more people are taking their stab at brewing kombucha and starting their own brands with unique flavors and formulations.

But, how do you choose the healthiest brand?

This article will tell you what to look for and compares 22 popular brands.

What is Kombucha?

In case you’re new to the drink or have tried it but are unsure of what it is exactly, kombucha is simply a fermented tea beverage.

Water, tea leaves, sugar, and a substance called SCOBY (Symbiotic Colony of Bacteria and Yeast) are what’s needed to make kombucha. The final product has a tea and slightly vinegary flavor that is also a tad fizzy.

Some brands try to minimize the vinegar flavor by adding sweetness and other ingredients like fruit juices and flavorings. Other brands don’t mask it with a lot of sugar and prefer to keep their kombucha more natural.

Number One Benefit: Probiotics

What makes kombucha so good for you is the probiotic benefit it provides. When you drink kombucha, you are consuming billions of healthy gut microbes that help your digestive system keep working as it should.1

I’ve read all kinds of health claims on the websites of kombucha brands and some are a bit of a stretch. But, modern research has shown us time and time again that good microbes are responsible for so many aspects of our good health.2

When comparing kombucha brands this is our number one consideration. Some brands are pasteurized which kills the live cultures (which defeats the purpose of drinking kombucha for better health). Brands do this to stop alcohol formation which I’ll cover at the end of the article.

If you see “pasteurized” on a kombucha label, pick a different brand.

Here’s How Some Popular Brands Compare

For comparison sake, I’ve looked at just one flavor from each brand and tried to choose “original”, when possible. Other flavors may have slightly more or less calories, sugar, and caffeine.

Kevita Master Brew Kombucha

kevita masterbrew

Note: Kevita is currently being sued for false advertisement. Although they advertise live cultures, it has come to light that Kevita actually uses a pasteurization technique to keep their kombucha from further fermenting on the store shelves. It is unclear what their unique method does to the active cultures but traditionally pasteurization kills many of the beneficial probiotic organisms in kombucha.

  • 4 billion CFU’s of live probiotics
  • 66.5 calories per bottle
  • 15.2 grams of sugar
  • 76 mg of caffeine
  • Sweetness enhanced with stevia
  • 100% organic
  • No artificial ingredients or preservatives.

Verdict: This is a solid brand health-wise but may have too much caffeine for some. They increase the natural caffeine with green coffee bean extract. They also make a line of probiotic soda’s but these aren’t classified as kombucha.

Alcohol Content?

All 100% raw kombucha or fermented tea products will contain alcohol. Most are under .5% to avoid being classified as an alcoholic beverage. There has been some government scrutiny in certain States because, although they leave the factory at under.5% alcohol, under the right conditions fermented tea products can continue to ferment and produce more alcohol.

The only brands that would just contain zero or trace amounts of alcohol are the pasteurized ones and these aren’t true kombucha and offer little, if any, health benefits.
simple truth

Caffeine Levels

Because most kombucha is made with traditional tea leaves, it will contain some caffeine. More if you make it yourself, less if it’s store bought. Generally, the caffeine is 15 mg or less per bottle since most are diluted to meet the below 5% alcohol standard. Brands that add coffee flavor or yerba mate will have more caffeine.

Make Your Own?

Brewing kombucha isn’t rocket science and you can pretty easily make your own.

Amazon.com sells kits with everything you need and once you have SCOBY, you can keep using it over and over again.

This allows you to experiment with different flavors and ingredients and will save you a lot of money. However, with fermentation, there is always a slight risk of contamination from undesirable microbes that could ruin the taste or even make you sick.

If you decide to make your own kombucha, follow the instructions and know what signs to look for that reveal a contaminated batch.

    Beware of the sugar numbers. Bottle sizes vary making the sugar level not comparable. It would not have required much work to present sugar as a % instead of a raw number per bottle.

    I thought this article would show tested results as opposed to what is published by manufacturers etc. However, I read it and wanted to share. I was alerted that GTS uses a synthetic scoby. Not a natural or organic product so not sure how it claims to be organic? Would really like to see tested products.

      How can scoby be synthetic? It’s made from living organisms. Where did you read this? Also, bacterial/yeast cultures are by definition natural and organic.

    Also, when reviewing test results, keep in mind that many kombucha companies add lab-grown probiotics at bottling. Doesn’t convey the benefits of fermentation (which increase greatly with the longer fermentation only possible by small-batch), but definitely better than nothing!

    Hey, great article! Did you know that a “CFU” test (colony forming units) only costs about 15 bucks at a food science lab and will tell you exactly how many live organisms are in your kombucha? The results might surprise you. For anyone interested in a high-probiotic kombucha, please check out SOMA Kombucha from Portland, which has tested much higher in probiotics than any other brand we’ve tried (we don’t have some of the brands above here in Portland, so I hope they all have tons of probiotics!). It was also voted “Best Kombucha” in our recent “Best of Portland” reader survey, so we’re pretty proud of that. Thanks and keep spreading the kombucha message!

    Great post … Thanks for sharing so much great knowledge about all the different kombucha options! Humm was started in our kitchen – my mom taught me how to make kombucha 25 years ago. All Humm flavors are certified organic (since 2014) and every batch now is verified Non-Alcoholic … we never dilute, manipulate or pasteurize. https://prn.to/2OPo2wj

    I’m not trying to say anything bad about raw Kombucha. I know it’s a local market that support each other. But in Thailand, ridiculous, somebody who produce and selling raw Kombucha, talked bad about Kombucha pasteurized. Said pasteurized no benefits left.. Really not true! Only that they’re not able to produce pasteurized process. Because needs high technology and very machine, need Analysis test to control good acid. So, homemade for me.. I don’t like. I hate the test of raw. They even over grown bacteria in my stomach, make it crumbs. No raw for me. Not save at all. If you drink Kombucha with good taste. I’m sure you found the pasteurized one but still live bacteria for sure.

    I don’t understand American people who drink Kombucha. Why they think that probiotic can stay in Kombucha? I think they put it later in the last process. In my lab, no probiotic left much in Kombucha raw, and after you drink, they’re no longer in stomach. The best of kombucha is the acid that can help liver, for detox process in body and support probiotic function. Kombucha is prebiotic. So, Kombucha pasteurized, means more safe, more taste, no alcohol. If you want probiotic, find some Kombucha tablet and put in your ass. Those probiotic will stay better. Or Kombucha capsules that can terminate directly in stomach. For best results of getting probiotic. … And you know, after you drink Kombucha pasteurized , many good bacteria will produce probiotic themself in your body. Because it called Prebiotic.
