Chill as low as possible, then let sit x 60 min before transferring to FV.

Chill to 48F, oxygenate, clarity firm, and then pitch yeast slurry

Ferment at 48F x 7-9 days until near end of fermentation, then raise 2F/ day to 64F.

Total in primary ~18-20 days

Check pH at end of fermentation, target 4.3

Then cold crash x 7 days, no gelatin. Keg without biofine. Pressurize to close lid then lager x 4 weeks.

After 4 weeks, pull 1/2 pint of sediment and add 5 mL biofine. Pull 1/2 pint of sediment after 7 days then carbonate.
