jclash4686, I would add more LME/DME instead of brown sugar. If you're impatient, you can run over to Arbor's, since they're also in W. Islip. Getting an 8% brew ready by Christmas doesn't look very promising. Maybe M.L. King day... How about a wheat beer?
I made a chile beer last year with smoked serranos and panca peppers. I added the peppers, in a small hop bag, about halfway through the three week primary. I can't help you with the chocolate. I'm experimenting with a double chocolate stout right now. If you do some digging you'll find a wealth of info on here. Cheers, pete
