Homemade kvass made from rye crackers will quench your thirst in the summer heat. This version of the drink, prepared by yourself, is much healthier compared to the factory version, because it does not contain dyes and various additives. At home, a Russian drink is prepared by fermenting malt and crackers. You can dry a loaf of Borodinsky for kvass. It will add tartness to the drink. This kvass can not only be drunk, but also used as a dressing for okroshka.
