Then I strained out the solids and had a nice clear brown liquid with a very slight fizz and a taste that took some getting used to. Turpentine came to mind at first. But I'm warming to it, and I'll keep on experimenting.

I read that kvass is traditionally brewed with sugar added, but I thought: surely in medieval Russia they would not have had that, so I wanted to try it with no sweetener, not even honey. Again, I'm getting to like the taste.
It has only a very slight fizz (a bit less than kefir), and it won't keep long. But it is refreshing, and leaves a good feeling in the belly.
