Kombucha: The Best and Worst Brands
Kombucha was once a niche drink, that then surged in popularity during 2015-2020. Many manufacturers entered the market, but since then, many are missing-in-action, as the market become too crowded.
How do you choose the healthiest brand?
What is Kombucha?
If you’re new to the drink and are unsure what it is, 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 slightly 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, preferring to keep their kombucha more natural.
Is Kombucha healthy?
Kombucha provides probiotic benefits. When you drink kombucha, you consume billions of healthy gut microbes that help your digestive system keep working as it should.
I’ve read all kinds of health claims on the websites of kombucha brands, and some are a bit of a stretch.
When comparing kombucha brands, this is our number one consideration. Some brands are pasteurized, which kills the live cultures (and 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.
The best and worst Kombucha brands
For comparison, I’ve looked at one flavor from each brand and tried to choose “original” when possible. Other flavors may have slightly more or less calories, sugar, and caffeine.

Verdict: Unity Vibration is a 100% raw kombucha classified as an alcoholic beverage because it contains more alcohol than the .5% limit. It’s one of the highest in sugar and only for those at least 21 years of age.
Does kombucha contain alcohol?
All 100% raw kombucha or fermented tea products contain alcohol.
Most are under 0.5% to avoid being classified as an alcoholic beverage. Under certain conditions, fermented tea products can continue to ferment after leaving the factory, increasing alcoholic content.
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.
Does kombucha contain caffeine, and how much?
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. Brands that add coffee flavor or yerba mate will have more caffeine.
How to make kombucha
Brewing kombucha isn’t rocket science, and you can fairly easily make your own.
Amazon sells kits with everything you need, and once you have SCOBY, you can keep using it repeatedly.
This allows you to experiment with different flavors and ingredients and will save you a lot of money. However, fermentation always has 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.
