Secondary: 21 days @ 8.8° C
Notes
After infusion, make sure the temp stabilizes at 111* rest there for 20 minâs to bring mash pH down and increase clovey character of finished beer. Heat if necessary to maintain temp. Heat slowly to 150* and hold until iodine tests negative (40-60 minâs). Slowly (10 minâs) bring up to 170* and hold for 5 minâs. Do not let the sparge water get over 170* and do not let lauter runoff drop below 1.008 to avoid tannin extraction.
Boil:
Boil for 5 minutes to allow for protein coagulation to start and then boil for 1 hour with bittering hops and then with 15 mins remaining (at the 45 minute mark) add aroma hops. Do not add Irish moss or any other clarifying agents. Cool to 54*. Rack into open fermentation bucket and aerate significantly.
Ferment/Kegging.
At 54*, pitch yeast from an activator pack, or a small yeast starter and allow to rise to 63* (not above) and hold for primary fermentation. Primary should be complete 72 hours after initial fermentation begins (If healthy vigorous fermentation occurs) Let stand for 7-10 days in primary and then rack into keg/bottle. If kegging, cool to 48* and add forced CO₂ at 30psi@48*. Store at 48* for 3 weeks before drinking. Serve at 48* as well. For optimum flavor, let condition for 3-4 weeks. You can drink young, but flavor matures slowly.
