Kvass is a traditional Russian fermented beverage that has been enjoyed in St. Petersburg for centuries. It is made from rye bread, water, and yeast, resulting in a slightly tangy and mildly sweet flavor. Kvass is often served chilled and is a popular choice during the summer months. It is not only refreshing but also believed to have health benefits. You can find kvass in various flavors, including classic, cranberry, and cherry, at local markets and street vendors in St. Petersburg.
