Notes

Quickly chill wort to 60°F.
Transfer cooled wort to a sanitized fermenter, leaving behind trub and hop matter.
Oxygenate wort and pitch the yeast.

Ferment at 60°F for 2 weeks.
Lower fermentation temperature to 32°F to cold crash and begin the lagering stage.

Allow beer to lager for at least 1 week.

Package beer and carbonate to 2.5 volumes of CO2
If kegging, allow beer to condition for 1 to 2 weeks in the keg.
If bottling, after 2 weeks of bottle refermentation. Condition carbonated bottles at 32-40°F for 2 to 3 weeks.
