In case anyone is wondering about the name, it's a Slavic fermented bread drink that's much less alcoholic than beer (and commercially canned versions are near zero alcohol). It's one of my favorite chilled summer drinks, and you should be able to find it in Slavic stores in the US as well.

There is a cold cucumber soup that uses kvass as its base. I would recommend giving that a try as well.

Okroshka? Yeah I love that stuff. I'm vegetarian, replacing the sausage with a vegetarian one (or leaving it out) works well. I followed this recipe:

The Life of Boris also has a great video on making Kvass:

though I haven't gotten around to trying it, I've only had commercial bottled and canned ones. I imagine if you make it yourself you'll have a slightly more alcoholic outcome.
