Guinness Draught clone
(5 gallons/19 L, all-grain)
OG = 1.038 FG = 1.006
IBU = 45 SRM = 40 ABV = 4.2%

Ingredients
5.0 lbs. (2.3 kg) English 2-row pale ale malt
2.5 lbs. (1.1 kg) flaked barley
1.0 lb. (0.45 kg) roasted barley (500 °L)
12 AAU East Kent Goldings hops (60 min) (2.4 oz./68 g of 5% alpha acids)
Wyeast 1084 (Irish Ale) or White Labs WLP004 (Irish Ale) yeast (2 qt./2 L yeast starter)
0.75 cups corn sugar (for priming)

Step by Step
Heat 2.66 gallons (10 L) of water to 161 °F (72 °C) and stir in crushed grains and flaked barley. Mash at 150 °F (66 °C) for 60 minutes. Stir boiling water into grain bed until temperature reaches 168 °F (76 °C) and rest for 5 minutes. Recirculate until wort is clear, then begin running wort off to kettle. Sparge with 170 °F (77 °C) water. Boil wort for 90 minutes, adding hops with 60 minutes left in boil. Cool wort and transfer to fermenter. Aerate wort and pitch yeast. Ferment at 72 °F (22 °C). Rack to secondary when fermentation is complete. Bottle a few days later, when beer falls clear. If beer is kegged, consider pushing with a nitrogen blend (see the Jan-Feb 2005 issue for more information on this).

To get that "Guinness tang," try this. After pitching the yeast to your stout, siphon 19 oz. of pitched wort to a sanitized 22 oz. bottle. Pitch bottle with a small amount of Brettanomyces and Lactobacillus. Cover bottle with aluminum foil and let ferment. When beer in bottle is done fermenting, pour it in a saucepan and heat to 160 °F (71 °C) for 15 minutes. Cool the beer and pour and pour it back in the bottle. Cap bottle and refrigerate. Add to stout when bottling or kegging.
