Definition & Meaning of "kvass"

What is "kvass"?

Kvass is a traditional fermented drink that originated in Russia and is also popular in other Eastern European countries. It is made from fermented bread, water, and sometimes fruit or herbs. The bread is typically made from rye flour and is left to ferment with water and sugar for several days to produce a tangy and slightly sour liquid. The resulting liquid is then strained and flavored with fruit or herbs, such as mint or berries. Kvass has a low alcohol content and is often consumed as a non-alcoholic alternative to beer in Russia. It is believed to have a range of health benefits, including aiding digestion and boosting the immune system. Kvass is often consumed during the summer months and is sometimes used as a base for cocktails or other mixed drinks.
