After some discussion with family, I'm looking to make a chocolate/cherry brew. I'm going to use my red ale recipe (which is quite malty) for the backbone. For economic and laziness reasons, I purchased a 16 oz bottle of "cherry concentrate." The bottle says ~12 1/2# cherries are used to produce. Is this too much to chuck into a 5 gallon batch? I'm assuming it would go into the secondary, as if I were using whole berries. Any idea how much cocoa powder I should use to balance with the cherries? How about adding lactose, and how much to this menagerie? Any input would be greatly appreciated.
