Looks like this
thread ran dry. Well, I've made bread kvass a bunch of times since posting here last, and actually have a batch brewing on the counter now as I type this. It's really hard to mess up, honestly.
Here's what you need to make around 2 gallons:
- Loaf of bread. Traditional way is to use a rye loaf, but really you could use any type. You're going to toast it, so get a sliced loaf if you're doing it in the toaster.
- Raisins, golden or dark.
- Sugar, 3-4 cups.
- Active, dry yeast, 3/4 oz. They sell it at any grocery store in a 3-pack, you'll use all 3 packs.
So, the process:
Boil water in a big soup pot. While it's boiling, you could toast your bread. The darker you toast it, the darker the brew, you could play around with it, but you definitely want to at least toast it so it's very dry. I prefer unsliced bread, I tear it up into big chunks and toast it on my grill outside. Big chunks are easier to fish out of the water later, but either way you'll be fine.
So your water boiled and your bread is toast. Turn off the heat, toss a healthy handful of raisins into the pot, toss in your bread, cover, and let it sit just like that for 10 hours or so.
After that, you're going to fish out the bread. Like I said, big chunks are easier to fish out, and also to squeeze after getting them out, so that you don't lose too much water from the pot.
So the bread is out, the raisins are still in, and now you toss in your yeast and sugar. I find 3 cups of sugar is just right for me. Stir it up a little, and let it sit on the counter for another 10 hrs or so, covered with a lid, occasionally giving it a quick stir.
After that, strain through a cheese cloth, pour into water jugs with a screw-on cap, stick in the fridge. You need to be careful for the next few days, unscrewing the caps every few hours to release the gas, else boom!!! all over your fridge.
The kvass will be fairly sweet when freshly made, will lose sweetness as the yeast eats up the sugar. I like it best on the 3rd or 4th day. Enjoy!
