We went to a local traditional Lithuanian restaurant, Etno Dvaras, where we shared many tasty dishes. (I’ll try to look it all up later..)
And then of course I asked what is the national drink of Lithuania and both Simona and the server replied in unison “kvass!”. So I had one, of course.
Kvass is the word in Russian. They might have said gira which is the word in Lithuanian. Either way it was the same beverage, the slightly fizzy, slightly fermented, result of soaking old bread in water and sugar, with maybe some fruit, and waiting a few days.
I am very glad to have tried it and probably won’t order it again.
