Batch 137, Magnum Opus Stout

I've been meaning to do a stout for my nitro tap. It's too late for St. Paddy day, but that's okay, it'll still be beer. "Magnum Opus" because the hops are all Magnum. Hurr.

10 gallon batch.

OG: 1.059
FG: 1.015
IBU: 38
SRM: 31

18 lbs 2-row
1.5 lbs chocolate malt
1.0 lbs crystal 120
1. 0 lbs flaked oats (Quaker)
1.0 lbs roasted barley
1.0 lbs wheat

Had a heck of a time getting the mash to the right temp. The thermometer said 160F, and I was aiming for 150, so I added a couple of quarts of cold water. Still at 160. Add more cold water, stirred, now at 140. Crap. Pulled some wort off into another pot (I knew I kept that old blue with white speckled emamel canning pot for something) and brought it to boil, added back, repeat, took about 45 minutes to get the temperature right. I think the thermometer got stuck, and stirring giggled (hahahaha! *jiggled*) it enough to get it to move.

60 minute boil

2 oz Magnum, 60 minutes

Wyeast London Ale III, pitched using my new 3 bucket method. I got busy with doing a second batch (back to back, good fun!) and forgot to pitch the yeast today. Remembered it by seeing the yeast packet sitting on the kitchen counter. Pitched it on March 10 in the small bucket, pitched the small bucket into the large buckets on March 12.


  1. Mar 18, 2013, gravity is at 1.016, going to let this sit a few more days to see if it will finish a little lower.

  2. "let this sit a few more days" my ass. I moved. The fermenters set in the garage at Lisa's place until May 4th, when I finally got around to putting this in kegs. Got the nitro tap set up also. I had taken the little disk out and was using it with regular CO2. I went ahead and put one of the kegs on the nitro.

    1. Oh, and I didn't bother to take another gravity reading, so I have no idea if this finished a little lower or not.
