HERE’S THE RECIPE FOR CZECH PILSNER WITH AN AMERICAN TWIST (ALL-GRAIN RECIPE FOR 5 GALLONS):

Note: This recipe is highly dependent on soft water, so if yours is high in minerals I strongly recommend diluting or substituting with distilled water. Portland’s water is very soft, so I add either a few ounces of acidulated malt or 15 mL lactic acid to the mash.

Grain:
9# German Pils malt
0.5# Munich malt
0.5# Caramel Pils malt
0.75# Carapils malt

Hops:
Crystal Whole Flower (or other noble variety), 4%AA, 1 oz, added first wort
Saaz Pellets, 3.9%AA, 1 oz, boil 60 min
Saaz Pellets, 3.9%AA, 1 oz, boil 20 min
Saaz Pellets, 3.9%AA, 1 oz, boil 5 min
Summit Pellets, 18.5%AA, 0.5 oz, boil 5 min
Saaz Pellets, 3.9%AA, 1 oz, boil 1 min
Summit Pellets, 18.5%AA, 0.5 oz, boil 1 min
Saaz Pellets, 0.5 oz, dry hop in secondary (lagering) vessel
Summit Pellets, 0.5 oz, dry hop in secondary (lagering) vessel

Yeast:
WYeast 2278 Czech Pils – I strongly recommend making a very large starter for this beer (as for all lagers). I typically make 1.5 gallons of starter well in advance, then decant the beer before adding the slurry to the wort.

Other ingredients:
1 Whirlfloc tablet, boil 15 min
1 tsp WYeast yeast nutrient, boil 15 minutes

Procedure (single decoction mash):
Mash in with 3.2 gal of 138F degree water for a protein rest of 122F. After 15 min infuse 2.2 gal 212F water for saccharification rest at 154F. After 20 min pull 1.5 gal of the mash, heat to boil while stirring almost continuously, boil 30 min then add to back to main mash for mashout at 165 F. Vorlauf, then lauter to get 8.75 gal in kettle (predicted gravity with 83% efficiency, 1.037). Boil 90 minutes, adding hops. Chill as quickly as possible to 52F.
Note: you will likely have to adjust times and temperatures to account for your system.

Ferment at 52F until fermentation appears to be slowing dramatically, then raise temperature to 60F for two days. If this is your first lager, don’t be alarmed by disgusting smells coming from the fermenter – this is normal and the beer will end up ok. Rack to secondary with dry hops (I use Cornelius kegs, because I can keep pressure on them and not worry about an airlock during cooling), then drop the temperature about 2F per day until you reach 35F. Lager for at least 3 weeks (5 is ideal), then keg or bottle. Prost!
