Ferment @50°F until 1.016. Then slowly ramp to 60 °F. Then move to ambient to finish. Cold crash for 2 days. Transfer to keg with clear beer draft system and campden tablet (apply 15 psi after transfer). Lager for ~4 weeks. Transfer to serving keg with clear beer draft system and campden tablet.
9/2: mash temps of 131 °F / 148 °F / 153 °F / 163 °F. 1.051, 5.5 gal. Added 6 oz of DME to boost to 1.054.
9/3: pitched yeast with clarity ferm and 90 s pure O2 at 0.5 L/min. 52.5 °F.
9/4: CO2 activity started in am.
9/8: 1.026. Plenty of activity.
9/11: 1.016. increased temp to 53 °F in AM. Up to 54 °F in PM.
9/12: 55 °F in AM. 56 °F in PM.
9/14: 58 °F in AM. 60 °F in PM.
9/15: 62 °F.
9/16: 63 °F.
9/17: started crashing.
9/20: reached 39.6 °F.
9/24: 1.012. keg with gelatin, campden tablet, clear beer draft system, and quick carb lid.
9/30: pretty solid! Water is slightly off. Mildly acidic finish that accentuates bitterness a bit too much. Malt character is great though and beautiful color.
11/13: has become really great as it sits and lagers. Beautiful color and nice toasty malt character without any caramel. Possibly a bit too much Noble hop bitterness. Likely resolves with a higher OG.This Recipe Has Not Been Rated
