Notes

Double crush to fine. Start mash at 147º F for 45 minutes. Allow mash to settle 10 minutes and begin recirculation pump. Increase temp to 156º F and mash another 20 minutes while recirculating--then Mash out 10 minutes at 168º F. Lift and let drain, press bag.

Boil for 15 minutes then begin following hop schedule for 60 minutes.

Chill to 62ºF and pitch along with clearzyme. Ferment at temp until attenuation is ~75% completed, and then ramp temp to 72ºF by 5ºF/day and hold for 3-5 days to mature. Cold condition by reducing temp to ≤ 38 ºF slowly and add Silafine, Hold for 4-7days. Bottle to carbonate.
