I'm starting my holiday brew, trying for a moderately intense and not too sweet chocolate stout. The base recipe is a partial mash oatmeal stout, and I'm racking onto a small package of cacao nibs (maybe 2 oz? Not the big package). Lactose would be 4 oz.
I want to include some cocoa powder in my boil, but don't know how much or when to add it. I've seen everything from 2oz to a half pound and up. It's a 5 or 5.5 gallon batch - the recipe hasn't been finalized yet. And does dutch-process matter, or just Hershey's regular?
Any help will be appreciated.
