Notes
Metts Potter of Morrow, OH, a member of the Bloatarian Brewing League homebrew club, won a gold medal in Category 2: Pale European Beer in the 2023 National Homebrew Competition Final Round in San Diego. Potter’s Kölsch earned gold out of 131 entries.
Bulk treat 10 gal. (37.85 L) RO water with 2 g each pickling lime, gypsum, and calcium chloride.
Follow low-oxygen brewing practices to the extent possible with your system. Techniques employed were pre-boiling and chilling strike water, purging tubing and grain bed with CO2, underletting mash, using a mash cap, and conducting a full-volume mash to avoid need for sparging.
Dough in at 144°F (62°C), then step mash at 148°F (64°C), 153°F (67°C), 163°F (73°C), and 170°F (77°C) for 45, 10, 45, and 15 min., respectively.
Boil gently with kettle partially covered for 60 min. Adjust pH to 5.1 with 15 min. remaining in boil. Add Whirlfloc with 5 min. left in boil.
Chill rapidly and transfer clear wort to fermenter, minimizing carryover of trub and hop matter as much as possible. Oxygenate to 16–18 ppm. Pitch yeast at 62°F (17°C) and allow to free-rise to 66°F (19°C) at about 60% of expected attenuation.
Closed-transfer to CO2-purged keg with 3-4 remaining gravity points and spund to 2.8 vol. (5.6 g/L) CO2. Lager until clear.
