I got about 2 lbs of cranberries leftover from Thanskgiving sitting in the freezer. I was thinking of adding them to 5 gallons of American Brown Porter (American here means more alcoholic and Cascade flavor hops, clone of Flossmoor Station's Pullman Brown). I'm planning to add a 1 lb to the secondary, tasting it after a couple of days, and possibly adding more cranberries depending on the taste.
Questions: Is it possible that 1 lb of cranberries would be too much as an initial addition? Should I run the cranberries through a blender in addition to the freezing?
Thanks
