A long time ago a small brewery here in Pittsburgh (East End Brewing) made a Kvass. I loved it. When I talked to the owner/head brewer he said just using bread resulted in too low OG to bother so they adjusted the recipe. Both places referenced in the article used bread yeast. Comments, suggestions, and critiques appreciated.
Here is a link to an article about the beer. http://www.themadfermentationist.com/2010/10/brewing-kvass-at-east-end.html
So I want to make something similar to this. here is what I came up with.
3 lbs Briess Pilsen Light DME
2 lbs Briess Rye LME
.75 oz LD Carlson Lemmondrop Hop pellets @ 30 min
6g Caraway @ 30 min
OG 1.042
IBU 9.81
PA 3.94
