* Bread Kvass is an Eastern European fermented beverage typically made with black or other rye bread and is imbibed as a thirst quencher in the summer or as a health elixir. It is also used as a cooking ingredient for soups like Russian botvinia and some versions of okroshka (some recipes call for buttermilk in place of the kvas as a souring agent), and Polish żurek.
* Beet kwas is used in Polish Christmas Eve Beet Soup.
Although it is fermented, this slightly sweet beverage is considered nonalcoholic (0.05% to 1%). It can be made with the addition of fruits like strawberries and raisins or herbs like mint. A distinction is made between bread kvas and beet kvas. Not only is kvas popular in Russia, Ukraine and Poland, it is enjoyed in Belarus (kvas), Latvia (kvass), Lithuania (gira), former Soviet states like Georgia, Kazakhstan and Armenia, and is even known in China (géwǎsī/kèwǎsī).<br>
