Background
Kombucha is made by fermenting tea (black, green, red, or white) with sugar and other ingredients with specific types of bacteria and fungi.
Kombucha contains alcohol, vinegar, B vitamins, caffeine, sugar, and other substances. The cultures used to make kombucha are called SCOBY (Symbiotic Culture of Bacteria and Yeasts). They commonly contain Acetobacter xylinum, Gluconobacter, and Saccharomyces cerevisiae.
People use kombucha for aging, diabetes, memory, obesity, and many other conditions, but there is no good scientific evidence to support these uses.
