I have attempted to make Cherry Stout before. I did the first fermentation then racked off in to a new container with Cherry concentrate(from cocktails) when it came round to drinking it didnt have any cherry flavour at all. more marmite. I love marmite so it was acctually really good. and i tried again with letting it sit on fresh cherrys again, again marmite. Is it that the secondary ferment is killing the taste?
