Recipe Notes
Mash grains at 152¡ F and hold for 60 minutes. Mash out at 170¡ F and sparge with 170¡ F water. Collect enough run off to end up with 5 gallons after a 50-minute boil (approximately 6 gallons). Bring to a boil and add the first hops. Boil for 35 minutes before adding the second hops and the Irish moss. After the 50-minute boil, chill to 63¡ F, and transfer to a fermenter. Take a gravity reading, then pitch the yeast and aerate well. Ferment at 63¡ F for one week to 10 days. Rack to secondary and let sit for a day at 65¡ to 68¡ F for a diacetyl rest. Lower the temperature back to 60 to 63¡ F and for one week. Keg or bottle afterwards.
