Partial Mash Porter

Category : General

Yield: 54 Servings

Ingredients (Help):
3 lb 2-row pale lager malt
10 oz Black patent malt
6 oz Crystal malt
4 lb Australian dark extract
11 AAUs
Doric yeast
1/2 c Corn sugar (priming)
Northern Brewer hops

Mash-in (6 quarts water) at 131-122 degrees, stir 3 minutes. Adjust pH to
5.0-5.5 (using calcium carbonate or gypsum). Protein rest 131-120
degrees for 30 minutes. Starch conversion 155 degrees for 60 minutes.
Mash out at 168 degrees for 5 minutes. Sparge with 2 gallons of 168-160
degree water. Bring liquid to boil and add extract and hops. Boil 60
minutes. The result is sweet, but very tasty. My next batch of porter will
be somewhat drier, tending toward stout. Changes will include a less sweet
extract (Scottish light), dropping the crystal malt altogether, bumping
the bittering hops up a point, adding an ounce of Fuggles 10 minutes
before the end of the boil for finish, and going to Edme yeast, which I
believe to be more attenuative. I'm also toying with the idea of adding 8
ounces of wheat malt to improve the head, which is the only real
defect this beer seems to have.
