Kvass is a traditional fermented Slavic and Baltic beverage commonly made from rye bread, which is known in many Central and Eastern European and Asian countries as "black bread". The colour of the bread used contributes to the colour of the resulting drink. Kvass's alcohol content from fermentation is typically low.

Can kvass get you drunk?

Usually, kvass contains not more than 1.5% of alcohol by volume, but if it stands for longer time, the concentration can become 2.5% or higher. Unlike beer, the kvass is generally considered to be a nonalcoholic beverage and is drunk by children of all ages without any limit.

What does kvass taste like?

It is non-alcoholic but many people say that it tastes somewhat like beer. Some others compare it to kombucha. Kvass is made with dried rye bread which is soaked in water and yeast is added. Some like to add other items such as raisins, honey, mint.
