Kvass is a traditional, fermented, non-alcoholic beverage in Russia, made from bread or grains, such as rye. It has a slightly sour, slightly sweet, and tangy flavor and is often flavored with fruits and spices like raisins, mint, or ginger. Kvass is considered to be a healthy drink, high in antioxidants and probiotics, and is widely consumed in Russia, especially during the hot summer months. The beverage is usually served cold and is often accompanied by light meals, such as bread or pickles, as a refreshing thirst-quencher.
