According to the FDA, any beverage containing more than 0.5 percent alcohol is considered an alcoholic beverage. In a bottle of Kombucha, unless otherwise labeled or regulated as 21+, you'd find trace amounts of alcohol, but not enough to be labeled alcoholic. I've written before about how I don't drink, however I wasn't going to rule out Kombucha just because it contains trace amounts of alcohol, when in fact naturally occurring low-levels of alcohol have been shown to increase feelings of happiness and well-being and decrease stress.
