Recipe: Opus 12, The Dubliners Stout

Posted: November 21, 2012 in Recipes

It’s Thanksgiving Break, so I have time to brew! Since this one will finish up right after the holidays, I wanted something that would be great in the dead of winter. So why not try my first Stout? This dry stout should be Guinness-like, and comes from this recipe on A traditional Irish stout for the masses named after a traditional Irish band for the masses! I had to make a few substitutions because my LHBS didn’t have everything I needed, but I think it will turn out pretty well. I also lowered the boil time to 40 minutes because of the AA of the Golding hops.

I used the same BiaB method as on my first all-grain attempt, with a few alterations. I used 3 gallons of water for the mash, heating to 158. It was 156 when I put it in the pre-warmed oven for the mash.

I also used 1 gallon of water heated to 170 for a sparge in a separate pot instead of a mash out. I sparged for 10 minutes, then combined the water for the boil. This was a lot easier than trying to mash out in the same pot, since it gives me room to stir the grain.

After this, I followed the normal routine: boil and ice bath to cool. Once cooled, I put the wort in the LBK, and placed that in the beer fridge. I checked it 1 hour later or so, and pitched the rehydrated yeast at 64 degrees.

My efficiency is hard to say. According to tastybrew, it’s about 49%. But, according to Brewer’s Friend, it’s closer to 80%! Guess I’ll need to figure out how to do that later. Seems lower with the sparge, so maybe the mashout is the way to go!
