Brewed an "improved" version of the Russian Imperial Stout yesterday. Dropped the Special B (too much raisin/prune), upped the oats to 2lbs (from 1lb), put the mash at a regular 152 or so, and didn't boil for almost 5 hrs.

My efficiency was really bad and so I ended up using 5.5lbs of molasses instead of 2lbs that I planned on. Ended up with 11.5G of 1.107 wort, which is what I wanted. I think next time better batch sparge calulations would help with efficiency - too much water, 2nd sparge was 8G first 5-6G etc. I spilled a lot on the ground so I would have had even more volume. Bump up grain bill for the lower efficiency.

Recipe was:
27 lbs Golden Promise
6 lbs Munich
5.5 lbs Molasses
3 lbs Roasted Barley
2lbs Oats (Quaker not instant)
1.5 lbs Chocolate malt
1 lb Wheat Malt
1 lb Black Wheat Malt
1 lb Debittered Black Malt
1 lb Crystal 60

3 oz Centennial 90 mins
1 oz Mt. Hood 90 mins
1 oz Fuggle 90 mins
2 oz Centennial 20 mins
1 oz Centennial 5 mins

Irish Moss

It's in plastic now, still lagging 'cause it's cold in the basement (59-60) 12 hrs later. It'll ferment out in plastic and then I'll rack it to glass for a few months and then rack it again onto oak cubes + Maker's Mark.
