Kvass is a fermented beverage made from black or regular rye bread. The colour of the bread used helps to make the colour of the drink. It is a non-alcoholic drink by Russian standards. This is because the alcohol content from fermentation is less than 1.2%. Overall, the alcohol content is low (0.05% - 1.0%). It is often flavoured with fruits or herbs such as strawberries, raisins or mint. Kvass is also used for preparing a cold summertime soup called "okroshka".
