Batch size: 5 gallons (19 liters)
Brewhouse efficiency: 75%
OG: 1.052
FG: 1.011
IBUs: 35
ABV: 5.5%
MALT/GRAIN BILL
10 lb (4.5 kg) Gambrinus Pilsner Malt
HOPS SCHEDULE
4 oz (113 g) Citra [12% AA] at knockout
3 oz (85 g) Citra at dry hop
DIRECTIONS
Mash at 155°F (68°C) for 45 minutes. Boil for 90 minutes. Ferment at 55°F (13°C) with a diacetyl rest when fermentation is 70 percent complete (typically, at the end of the second day of fermentation).
To reduce DMS, collect only 4.5 gallons (17 l) in your kettle. Boil down to about 4 gallons (15 l) and then at knock out (with flame off), top up with 1 gallon (3.8 l) of chilled sterile water (a gallon jug of grocery-store water is best). This should bring your wort to 185°–195°F (85–90°C) and will get your wort out of the temperature danger zone where DMS precursors can redevelop.
YEAST
Fermentis Saflager 3470 (or similar yeast of Weihenstephaner origin)
BREWER’S NOTES
There are no bittering hops used in the recipe, as the large knock-out addition will provide enough bitterness. Target a mash pH of 5.3–5.4, with a wort pH of 5.15.
