Hey, I brewed a cranberry ale, "Bogged Down Blondie" five and a half weeks ago. I have tried a few bottles, very good, very dry, almost like a dry wine.
I used 4 lbs of crushed cranberries, threw them in after the wort had chilled to 170, and kept them in there until secondary. I am excited that it is mellowing out as much as it is, even more exited that yours came out so well!!!
