Lazy Lagoon Lager

Boil water then cool to mash-in temp of 155°F (68°C). Add crushed Campden tablets and mash in for a 1-hour rest until conversion is complete as indicated by the iodine test. Sparge with 170°F (77°C) water. Cooled with counterflow chiller to collect 5.5 gal. (20.8 L) wort at 60°F (15°C). Pitch a 2 qt. yeast starter, aerate well with O2 and ferment in primary for 10 days at 50°F (10°C). At SG 1.020 (5°P), rack to secondary for 7 days. At SG 1.018 (4.5°P), rack again for a 5-day diacetyl rest at 70°F (21°C), then at SG 1.016 (4°P) rack onto gelatin finings and lower to 34°F (1°C) to crash yeast. After 1 week, transfer to a 5-gallon keg and carbonate to 2.4 vol. (4.8 g/L) of CO2. After 3 days, filter to 1 micron while transferring to another keg. Counter-pressure bottle if desired.
