It’s very easy to make kvass – you only need hard, old bread which may be roasted and then submerged in water. 100-200g bread/Liter water. The next day filter the bread over a cloth and collect the water. Lactic acid bacteria which is normally present an bread and grains starts the fermentation. You may add yeast and a tablespoon of sugar to make sure that it will ferment. 2-5 days later you can drink your Kvass and it should taste like sour beer. Adding more sugar, fruit juice or fruits may increase the alcohol content significantly.
