2 lbs. (0.91 kg) Munich malt
14 oz. (0.40 kg) crystal malt (60 °L)
7 oz. (0.20 kg) chocolate malt
4 oz. (0.11 kg) black malt (500 °L)
4 oz. (0.11 kg) roasted barley (500 °L)
3 oz. (85 g) ground coffee (dark roast)
6 AAU Northern Brewer hops (60 mins) (0.67 oz./19 g of 9% alpha acids)

0.5 oz. (14 g) First Gold hops (0 mins)
Wyeast 1968 (London ESB) or White Labs WLP002 (English Ale) yeast (1.5 qts./1.4 L yeast starter)
¾ cup corn sugar (if priming)

Step by Step
Mash at 154 °F (68 °C) for 60 minutes in 16 qts. (15 L) of water. Boil wort for 90 minutes, adding hops at times indicated. Ferment at 68 °F (20 °C). When you are ready to bottle or keg, coarsely grind 3.0 oz. (85 g) of dark roast coffee beans. Place in French press and add 200 °F (93 °C) water. Let grounds steep for 8 minutes, then pour coffee into keg or bottling bucket. Rack the beer into the coffee.

Extract with grains option:
Replace pale ale malt with 3.3 lbs. (1.5 kg) of light liquid malt extract, and 1.5 lbs. (0.68 kg) light dried malt extract. Place crushed grains in a large steeping bag and steep, in your brewpot, at 154 °F (68 °C) for 45 minutes. The volume of the steeping water should be 5.25 qts. (5.0 L).  After steep, rinse grains with 2.0 qts (~2 L) of 170 F (77 C) water. Add water to make 3.0 gallons (11 L) of wort, add dried malt extract and boil for 60 minutes, adding hops at times indicated. Cool wort, transfer to fermenter and top up to 5.0 gallons (19 L). Aerate and pitch yeast. Ferment at 68 °F (20 °C). When you are ready to bottle or keg, see instructions in all-grain recipe for how to add coffee.
