Borș is a traditional fermented product hailing from Romania. It is made by fermenting wheat bran, sometimes together with cornmeal and bread slices. Borș can be enjoyed plain, but it is often used to make traditional soups (ciorbă).
It is mostly available as a homemade beverage produced by local farmers who sell it at traditional markets, though commercial versions are also available. Borș is packed with nutrients and probiotics and is often promoted as a healthy and nutritious drink, as well as a great hangover cure.
