Mash 2-row, corn, and wheat at 146° F (63° C) for 50 minutes. Raise to 155° F (68° C) and hold for 15 minutes. Mash out at 168° F (75° C). Collect wort.
Boil for 70 minutes. Cool to 67° F (19° C) and pitch starter (Boulevard uses a proprietary house Belgian yeast; the suggested strains are purportedly closest in character). Ferment at 70° F (21° C) until high krausen.
One day later, boil 1 lb corn sugar (or 1.5 lb if kegging) with enough water to dissolve, then cool and add to primary. Ferment until terminal gravity of 1.009 is reached. Rack on to dry hops and hold 3 days. If bottling, prime with 1 cup (207 g) of corn sugar at packaging for approximately 3.3 volumes of CO2. If kegging, carbonate to 3.3 volumes.
