I found both dark and light rye bread at the store but it was the factory-made kind. I definitely made mistakes with both batches including adding way too much bread to the light kvass.the bottles need a day to carbonate then we shall see how well they turned out. Not that I have any reference for the flavor.
I am from a place where kvass is made and drink it quite often. The difference between store bought and homemade stuff can be massive. Stuff that comes in cans tastes like bread flavoured soda or beer that was sweetened too much. The stuff restaurants make tends to be very sour, on the other hand.
