KOMBUCHA
Kombucha, also called tea kvass, is a sour-tasting fermented beverage of Russian origin made by fermenting sweetened tea with a SCOBY.
SCOBY is an acronym that stands for Symbiotic Colony of Yeast and Bacteria. The probiotic bacteria and yeast ferment the sugar and tea, and carbon dioxide is a by-product of the fermentation process.
Kombucha can improve digestion and strengthen the immune system and is a good substitute for soda.
