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.
You may have to make the bread yourself. There are also other types of kvass that use beets or fruit but are made in a similar fashion. This video does a decent job outlining the three main types. but there is almost infinite variety with this drink. I have seen some recipes that add herbs link hops to make it taste of beer or mint and berries.
I'm mostly interested in the original flavors. I remember drinking some as a child in Poland and so does my partner when she was a child in China.
