Seattle Pale Ale

Stone Pale Ale Yield: 5 Gallons (about 54 12-ounce bottles or 30 22-ounce bottles)

10 pounds plus 7 ounces crushed North American two-row pale malt
1 pound plus 4.2 ounces crushed 60L crystal malt
4.8 ounces crushed 75L crystal malt
About 9 gallons water
0.44 ounce Columbus hops (12.9% alpha acid)
½ tsp Irish moss
0.77 ounce Ahtanum hops (6.0% alpha acid)
1.19 ounces Ahtanum hops (6.0% alpha acid)
1 (35ml) package White Labs WLP007 Dry English Ale Yeast or WLP002 English Ale Yeast
1 cup plus 3 Tbsp light dried malt extract
Clean and sanitize all of your equipment.

Mashing In a 10-gallon insulated cooler, combine the crushed malts with 3 gallons plus 12 cups of 172°F water. The water should cool slightly when mixed with the grain. Hold the mash at 156°F for 20 minutes. Add 2 gallons plus 2 cups of 184°F water. The mixture should come up to 165°F.

Lautering & Sparging Lauter the mash. Once the liquid is lower than the level of the grain, begin to slowly sprinkle 3 gallons plus 1 cup of 168°F water over the grains to start the sparge. Continue sparging.

The Boil Set the brew kettle of wort on top of a propane burner and add water to bring the wort level up to about 6 gallons plus 12 cups, if needed. Bring the wort to a rapid, rolling boil. As it begins to come to a boil, a layer of foam and scum may develop at the surface. Skim it off and discard. Once the wort is at a full boil, put a hops bag containing the Columbus hops in the kettle and set a timer for 90 minutes. Stir the wort frequently during the boil and be watchful to avoid boil-overs. At 15 minutes before the end of the boil, stir in the Irish moss. At 10 minutes before the end of the boil, put a hops bag containing the 0.77 ounce of Ahtanum hops in the kettle. When the boiling time is over, turn off the heat and put a hops bag containing the remaining Ahtanum hops in the kettle. Cover the kettle and immediately begin cooling the wort as quickly as possible.

Pitching Yeast & Fermentation Once the wort has cooled to 72°F, discard the spent hops and check the specific gravity of the wort with a hydrometer. The target starting gravity is 1.057 (14 Plato). Transfer the wort to the primary fermentation bucket. Pitch the yeast (or prepare a yeast starter). Allow the wort to ferment through primary and secondary fermentation at 72°F until it reaches a specific gravity of 1.014 (3.5 Plato).
