In Russia kvass (russ.: квас) has been one of the most popular beverages for centuries, and with good reason. Kvass improves digestion and boosts metabolism. It helps prevent infections and keep the heart and circulatory system healthy. Kvass simply makes one feel better as it contains lots of vitamins, free amino acids, micro elements and lactic acid.

In the past almost everyone in Russia used to make their own kvass. Monks, farmers, doctors, noblemen and even solders left us plenty of recipes. At that time every sour drink was called kvass. It was brewed of fruit, berries or honey with herbs and spices, and also of bread. When people hear the word "kvass" today they usually think of a bread drink that has a pleasant sour taste and bread flavour. In Russia you can buy bottled kvass in many supermarkets. But homemade kvass tastes completely different. Just try and find out!
