They speak only Russian but that won't be a problem for you.
Very large selection of Georgian wines. Some Borzomi as well. But my favorite is Nabeglavi.
I would nearly kill to be able to buy it here. I was very addicted to drinking it while in Georgia. It is extremely yummy stuff.
I mean this stuff is very healthy and I believe the high intake of mineral water in Georgia is what gives them such long lifespans. And perhaps wine, and maybe all the walking too.
