You can brew a great lager faster than you think—but not too fast. For more on demystifying and streamlining lager brewing, see How to Stop Worrying & Lager.

Mill the grains and mash at 153°F (67°C) for 60 minutes. Raise the temperature to 168°F (76°C) for 10 minutes and mash out. Vorlauf until the runnings are clear, then run off into the kettle. Sparge the grains and top up as necessary to obtain 6 gallons (23 liters) of wort—or more, depending on your evaporation rate. Boil 90 minutes, following the hops schedule. After the boil, chill to 50°F (10°C); make sure the beer is at temperature before pitching the yeast. Ferment at 50°F (10°C) for 3 days; raise the temperature to 55°F (13°C) and ferment for 3 more days; raise the temperature to 60°F (16°C) and ferment 2 more days; raise the temperature to 65°F (18°C) and ferment 2 more days. Check the beer’s gravity and, if ready, proceed to packaging. If not, allow to sit 2 more days and check again.
Use low-mineral water—ensure at least 50ppm of calcium to convert the mash correctly. I prefer to add a little calcium chloride to add “fullness” to the beer. Keep the chloride above the sulfate. To achieve ultra-clarity, use gelatin (or another fining agent) to clarify before packaging.
