I just brewed my first attempt of a chocolate porter that had 6 ounces of cacao powder in the boil at 15 minutes. And 4 ounces of cocoa nibs is the secondary for two weeks. I noticed a large amount of the powder settled out in the primary. The porter came out good but doesn't really have much of a chocolate flavor. Has anyone done this and had better luck getting a chocolate flavor? Like I said a large amount of cocoa powder settled out into the trub, is that normal?
