I bought an Arrogant Bastard yesterday, and damn, that is a good beer. I thought I should try to make some of this myself. I was planning on brewing today anyway, so I looked around for recipes and found about a dozen. They all seemed to differ on the grain, so I just went with my own grain bill, mostly based on what I had on hand and aiming for the proper color and ABV. All the recipes I found did pretty much agree on the hops, nothing but Chinook. The Chinook I used are the ones I grew myself in the garden last summer.
10 gallon batch
27 lbs 2-row
2 lbs Crystal 60
1 lb Wheat
0.5 lbs Chocolate malt
Mash at 153F, collect 12 gallons in boil kettle. 60 minute boil.
2 oz Chinook, FWH
1 oz Chinook, 60 minutes
1 oz Chinook, 30 minutes
2 oz Chinook, 10 minutes
Wyeast 1272 (most recipes say to use 1056, but 1272 is a superior yeast)
OG: 1.082, actual 1.082
IBU: 87 (just a guess, it seems Chinook ranges from 11 - 13% AA, and qbrew defaults to 11.5%, so I went with that)
I'm not sure what exactly happened, I hit exactly 12 gallons in the BK with two batch sparges. I ended up with exactly 10 gallons in the fermenter, and I nailed the OG. Nice! I hope it comes out good in the end.
