"Not For Summer" Russian Imperial Stout

Brew #2 today was going to be the fourth iteration of the Rye Porter that I'm trying to perfect. Unfortunately I keep forgetting to borrow someone's barley crusher, so that one wasn't happening today. Further down my list of beers to brew was a Russian Imperial Stout. It felt very ironic to brew a beer like this on an 85 degree day, but this should be tasting good by Winter time. This is the biggest beer I've ever done on my system, so it was interesting to see how much of an efficiency hit I took. I planned the recipe for 60% (I usually get 72%) and ended up at 57%, only missing my target by a few points. Definitely acceptable in my book!

Mash: 151F for 90 mins
14lb Rahr 2-row (60.9%)
5lb Pils (21.7%) - used this because I ran out of 2-row
1.5lb Roasted Barley (6.5%)
1lb Crystal 120L (4.3%)
.5lb Caramunich (2.2%)
.5lb Pale Chocolate (2.2%)
.5lb Chocolate Malt (2.2%)

2.5oz Nugget @ 75min (88.6 IBU)
2oz Fuggles @ 10min (8.5 IBU)

SafAle US-05

OG: 1.093
FG: 1.023
IBU: 97
SRM: 67
ABV: 9%
