How to make Kombucha
Kombucha is a tea based fermented drink that has become very popular in recent years for its supposed health benefits.
Kombucha is made by fermenting tea using a "symbiotic culture of bacteria and yeast" (SCOBY). The yeast component typically contains saccharomyces cerevisiae (instrumental in beer, wine, and bread making) as well as other species. The bacterial component almost always includes Gluconacetobacter xylinus to oxidize yeast-produced alcohols to acetic and other acids. After water, acetic acid is the main component of vinegar and gives vinegar its distinctive flavour.
