It's probably a little late to make your batch of "Guinness" for St. Patrick's day but here is a recipe for making Guinness at home. The original recipe is for an all-grain brewer, but I have listed the substitutions for the extract brewer,
Ingredients:
- 7 pounds, Crushed pale malt
2 pounds, Flaked barley
1 pound, crushed roast barley
1 ounce, bullion hops
3 ounces, northern brewer hops
1 tsp. CaCO3 (if you are in a soft water area)
yeast starter made from a bottle of Guinness
OG: 1045-1053
Extract brewers: Substitute 2 cans of a light extract for the 7 pounds of pale malt. Also, if you don't want to make a yeast starter use Whitelabs Irish Ale yeast or Wyeast Irish Ale yeast.
I generally boil at 60 minutes, 30 minutes and 15 minutes and add my hops in at those intervals. At the 15 minute mark, I also use Irish moss to help settle the solids.
