Notes

Mash at 147º F for 40 minutes, allow mash to settle for 10 minutes and begin recirculation pump slowly. Increase temp to 155º F for another 20 minutes while recirculating. Lift bag and let drain for 5-10 minutes, gently squeeze remaining water.

Boil for 60 minutes following hop schedule. Begin chill to ~175-180º F and stop chilling. Whirlpool 15 minutes with final hop addition. Looking for only a whisper of hop aroma in the the finish.

Continue completion of chill and pitch at 66ºF, adding clearzyme at pitch. Hold temp until attenuation is 70-75% completed, and then allow temp to ramp temp to 76ºF by 5ºF/day and hold for 2-5 days to mature. Cold condition by reducing temp to ≤ 50ºF for 1+ week but no more than 2 , then bottle to carbonate.
