Weldwerks Brewing’s Weld Pilsner clone
Weld Pilsner is calculated to be 46 IBUs. This is a Czech premium pale lager, which the Beer Judge Certification Program (BJCP) style guidelines state is between 30–45 IBUs. Being hop heads, of course Weldwerks went over the style guidelines, even if it is only by 1 IBU.
Weld Pilsner clone, All-Grain
(5 gallons/19 L, all-grain)
OG = 1.051 FG = 1.009
IBU = 46 SRM = 3 ABV = 5.5%
Ingredients
10.3 lbs. (4.7 kg) Gambrinus Pilsner malt
7.1 AAU Hallertau Magnum hops (first wort hop) (0.5 oz./14 g at 14.3% alpha acids)
1.9 AAU Saaz hops (30 min.) (0.5 oz./14 g at 3.75% alpha acids)
7.5 AAU Saaz hops (15 min.) (2 oz./56 g at 3.75% alpha acids)

¾ corn sugar (if priming)
Step by step
This recipe uses reverse osmosis (RO) water. Adjust all brewing water to a pH of 5.5 using phosphoric acid. Add 1 tsp. calcium chloride to the mash.
Mash the Pilsner malt in 3.25 gallons (13.3 L) of water at 148 °F (64 °C) for one hour and then mash out at 168 °F (76 °C). Vorlauf until the wort is clear and then run off into the kettle. Sparge grains with enough water at 168 °F (76 °C) to collect 6 gallons (23 L) in the kettle. Add the first wort hop addition to the kettle as wort is being collected. Boil wort one hour, adding remaining hops at times indicated and Whirlfloc with 15 minutes remaining. The target boil pH is 5.1–5.2 for hot break production. If needed, add lactic acid to adjust pH mid-boil.
Cool wort to 55 °F (13 °C) and leave at that temperature for three weeks in primary fermenter. Then raise temperature to 58 °F (14 °C) for three days. Transfer to a secondary lagering vessel (or remove the trub if able with your equipment) and lager at as close to freezing as possible for three weeks.
Bottle condition or keg and force carbonate as usual.
