kvass

Kvass is a traditional Eastern European fermented beverage made primarily from bread, usually rye. It has a mildly tangy, slightly sweet flavor with a hint of malt and a low alcohol content, typically around 0.5%. The fermentation process involves natural yeast and bacteria converting sugars into alcohol and carbonation, giving kvass its fizzy quality. It is often enjoyed as a refreshing drink, rich in probiotics, which can support digestive health. Kvass is popular in countries like Russia, Ukraine, and Belarus and can be found in bottles or on tap in local markets.
