Lol @ put employees in your beer.
I racked a porter onto 6 oz of nibs. Looking forward to the results.
If I were to do it again I would grind/crush the nibs a bit more, soak the nibs in some unflavored vodka, starting on brew day then strain the vodka-nibs, put a sanitized straw in the bottle, then put it in the freezer. This causes the cocoa butter and water to freeze it's way up the straw, eliminating some of the cocoa fat which reduces the head of the beer and causes it to be slick. I might do this twice actually.
and add at bottling. Basically this way you're making a chocolate extract and adding it with the priming sugar.
Read about that freezing technique on here somewhere, and looks like a great idea.
Nibs are pretty expensive though in comparison to cocoa powder, but if you can find some unsweetened cocoa powder WITH NO COCOA BUTTER added, then try that with the vodka and the freezing technique. Should give a pretty similar result to the nibs as long as you can find some quality powder without any additives!
