Hi guys. Have you ever tried kvass? It is a traditional slavic drink known at least since 989 year. It is made of fermented roasted dry black/rye bread. It used to be very popular in almost all slavic regions - from Poland, through Belarus and Ukraine to Russia. Now it is popular only in three last and also in Lithuania (probably because of its history, Polish-Lithuanian Commonwealth, when Lithuania was a large country on slavic regions). In Poland this drink is almost forgotten, but it is not so hard to get it. Not so much time ago, even in pre-war era, many people had been making it on their own in their houses, because it is easy to made it. (Well, I've heard so, but myself-made kvass seemed more like bread wine, and is was awful :D maybe someday I'll try again)
Anyway, kvass is a good alternative to all carbonated drinks and - due to its low alcohol contain, about 0-1%- also to beer. It quenches thirst, is cooling and very tasty. My favourite.
And snuffing Brasil Feinst while drinking cooled kvass is one of the most amazing things in the world.
