I batch sparge and with this much grain I get pretty crappy efficiency, only 60% in this case. This isnít all that bad of a thing. Low efficiency can end up making your beer taste much fresher and maltier than a beer with a similar OG and FG and high effeciency. In this case, it really worked and this comes across as balanced despite the ridiculous hop onslaught.
I just did a simple infusion mash at around 152 F. My method is to simply heat water to around 190 F and just add it untill I hit my temp. This is the same temp as my sparge water. I would hesitate to go any higher as it might lead to a cloying beer but you can go lower if you like your beer drier.
Iím not sure what changes I will make next time I brew this. Itís freakiní awesome if I say so myself. I think I might leave out the aromatic and buiscuit entirely and sub in three or four pounds of munich. I would also back off on the IBUís if I brewed this sucker with pellets (but I never will).
