I am about to get together the ingredients for making a cherry stout. I am going to add the cherries at flameout, but I have no clue how much to add. I want there to be a solid cherry taste in the stout. I also don't want to misjudge the amount of sugar the fruit will add, since I don't want my stout to end up too strong (ABV wise).
How much cherries should I add?
