I brewed a double chocolate stout which at first was going to be just a chocolate stout but i had some cocoa sitting around so i decided to throw it in with about 15 minutes left in the boil. I weighed it out and it was about 4 oz worth give or take a little. When i took the gravity I couldn't really taste any chocolate flavor in the beer. I've decided that i want this beer to have a noticeable chocolate flavor and I was thinking of adding more cocoa to the or unsweetened chocolate powder before i bottled. Just wanted some ideas from everyone. If it doesn't come out the way i want i'll just have to drink it and brew more beer. Either way win win. Thanks in advance.
