Brewed this recipe today! First time doing a partial mash, think it went pretty well. Ended up with an OG of 1.073 ish. I eyeballed the last pound of LME, so I may have added a little more. I probably didn't have the most consistent mash temp, so if it ends up with less fermentables and a slightly higher FG, I am fine.
Used 8oz of cocoa powder. Couldn't find any non-fat in time, though. Oh well!
Also, I used the Northern Brewer's NeoBritania Wyeast instead. Should be some good stuff, thanks!
