What is the name of this traditional Slavic and Baltic fermented beverage that is used for a flavor in Fruktime and commonly made from rye bread whose colour contributes to the resulting colour of the drink?
Kvass Kvass is a traditional Slavic and Baltic fermented beverage commonly made from rye bread, known in many Eastern European countries and especially in Russia as black bread. The colour of the bread used contributes to the colour of the resulting drink. It is classified as a non-alcoholic drink by Russian standards, as the alcohol content from fermentation is typically low (0.5–1.0%). It may be flavoured with fruits such as strawberries and raisins, or with herbs such as mint.
Berliner Weisse Berliner Weisse (German: Berliner Weiße) is a cloudy, sour beer of around 3% alcohol by volume. It is a regional variation on the white beer style from Northern Germany, dating back to at least the 16th century. It can be made from combinations of malted barley and wheat, with the stipulation that the malts are kilned at very low temperatures to minimise colour formation. The fermentation takes place with a mixture of yeast and lactic acid bacteria, a prerequisite that creates the lactic acid taste, a distinguishing feature of Berlin Weissbier.
