Delicious stuff, but the word Kvass (Russian word for leaven?) seems more like a sound of exasperation than a delectible treat. I highly recommend it, not least of all because the ingredients are just so darn simple. Rye, sugar, water. Either some Ukranians have found a way to make real food for real people, or they are being incredibly modest about the ingredients (perhaps to hide corporate secrets about the true chemical makeup required to mix tasty beverages). Best tasting soda I’ve had in ages. Taste some yourself and see…
