I kegged my breakfast stout Friday. Its a big beer, 12.5% and I really had to work hard to make the coffee shine (peppers and chocolate were used) so I did 2 oz of decently ground beens at flameout, steeped for 15 minutes, then a hit press at bottling. Boiled some water, added it to the press, let it sit while I cleaned the keg, got ready, then I added the steep (also made ground chocolate in it.)
I just lowered the hop addition and IBUs at the start to counteract the increased bitterness from the coffee. I'll update tomorrow with my first sample.
