Another recipe from Main Street Homebrew. This is patterned after Deschutes Brewing’s Black Butte Porter.

West Coast Porter
7lbs Amber malt extract
12oz Chocolate malt
8oz 80l Crystal malt
4oz Carafa Black malt
Irish Ale Yeast
1 1/2 oz Cascade hops @ 60 min
1 oz Cascade hops @ 15 min
1 oz Cascade hops @ 5 min
1/2 tsp yeast nutrient @ 5 min
1 tsp Irish Moss @ 45 min

The original recipe only called for about half as many hops - but I had some extra cascade hops in the fridge and I decided to take it up a step.
