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.
Pain de campagne Pain de campagne ("country bread" in French), also called "French sourdough," is typically a large round loaf ("miche") made from either natural leavening or baker's yeast. Most traditional versions of this bread are made with a combination of white flour with whole wheat flour and/or rye flour, water, leavening and salt. For centuries, French villages had communal ovens where the townsfolk would bring their dough to be baked, and the miches weighed from four to as much as twelve pounds. Such large loaves would feed a family for days or weeks, until the next baking day.
