Notes
Mash in at 67c for 90 minutes. Mash out at 72c.
At flameout, immediately whirlpool and chill wort. Aerate and pitch rehydrated dry yeast.
Ferment at 15c for approximately 4 days then increase to 18C until finished. FG should ideally be 1:008 or less for Kolsch to ensure dryness. Chill to 2c. Add gelatin, leave for further 2 days. Transfer to keg via filter and force carbonate at 2.5 vol. Lager at 5C for 3-4 weeks.
