Notes

Original Recipe by Charlie Papazian, Zymurgy Spring 1988
"Possum Porter"
OG: 1.062 to 1.066
FG: 1.020 to 1.024
8.8 lbs. Premium Extra Pale hopped barley malt and corn extract
1 lb. Black malt
1 lb. Crystal malt
3/4 oz. Chinook hops for bittering (7 HBU)
3/4 oz. Hallertauer hops for flavor
1 oz. Tettnanger hops for finishing
1/2 oz. Cascade hops for finishing
1 to 2 packets of yeast
3/4 cup corn sugar for bottling
--------------------------------------------------------------
My goal was to update the recipe to use more commonly available malt extract, ie. bulk LME unhopped. Crystal malt was probably a mid-range 40-60L; took a few liberties--the C45 will actually be Mecca Grade Estate's Opal 44 which is a hybrid caramel malt that still have about 30% DP, but I think it's unique flavor profile will add depth to the beer. Flaked corn is to try to get abit of the sweet corn character that must have come from the barely/corn extract and the multiple dark & crystal malts have the goal of adding depth/complexity to the overall flavor profile.
