Kvass

Kvass is a probiotic beverage made from rye bread. It’s a traditional Slavic and Baltic drink known as ‘black bread’, and popular in many Eastern European countries.Kvass can be flavored with birch sap, fruits such as strawberries and raisins, or with herbs such as mint. Kvass is usually served unfiltered containing its yeast, which adds to its unique flavor. It’s also an excellent source of vitamin B, lactic acid and simple sugars.Like kombucha, the fermenting process of kvass allows for beneficial bacteria that may improve digestion in the same way as other lacto-fermented foods.
