Kvass is yummy. It's either not hopped or not hopped very much. I get some every time I go to the closest big international market. I keep meaning to make some. The recipe is basically put bread in water, add sugar, wait, it's ready in two or three days.

Yeah. In the summer Russians have big tanker trucks of kvass on the streets, similar to what we use to transport gasoline in here in the states, and you bring like an empty two liter and give em a coin and they fill it up for you.

It's closer to mexican crema, but little sourer, like you mixed in a little sour cream.
