The term "kombucha" generally refers to a fermented beverage produced from a mixture of steeped tea and sugar, combined with a culture of yeast strains and bacteria. Some kombucha products also have fruit juice or other flavors added during production. The combination of sugar and yeast triggers fermentation, which may produce a kombucha with an alcohol content of 0.5% or more alcohol by volume.
Does TTB Regulate Kombucha?
Under federal law, if the alcohol content of kombucha is 0.5% or more alcohol by volume, at any time during production, when bottled, or at any time after bottling, the kombucha is an alcohol beverage and is subject to TTB regulations.
Kombucha is AT OR ABOVE 0.5% alcohol by volume at any time
