About This Beer
The second run of Owen’s League Casa Cerveza, brewed three weeks after the first — the same League of Brewers International Amber Lager kit, brewed identically. A good amber lager is worth repeating, and back-to-back brews of the same recipe are a sound way to get reproducible results dialled in early on.
The grain bill is the same Bestmalz-heavy Continental build: Vienna leading at nearly half the grist, Pilsen and Munich behind it, and Bestmalz Red X plus a touch of dehusked Carafa Special II for the amber colour, with Gladfield Sour Grapes acid malt setting the mash pH. Pacifica and Saaz again split evenly between a 60-minute addition and an 85°C whirlpool for roughly 20 IBU of soft, malt-forward bitterness.
Brew Day
As before: mashed at 65°C for 60 minutes with a 16.19 L strike, mashed out at 77°C, and fly sparged 17.02 L at 76°C to a 28.5 L boil. Pacifica and Saaz at the start of the 60-minute boil, Whirlfloc and yeast nutrient at 15 minutes, and the whirlpool charge held at 85°C for 15 minutes.
Fermentation
Two packets of Mangrove Jack’s M54 California Lager, rehydrated (100 ml water at 20–25°C, stirred to a cream for 8–12 minutes) and pitched. Fermented at 15°C for about a week, a diacetyl rest at 18°C, then a cold crash to 2°C and at least a week of lagering before packaging to 2.7 volumes.
The figures shown — OG 1.047, FG 1.008, 5.12% ABV, ~20 IBU — are the kit’s estimates at 75% efficiency.
