Source Notes:
December 2019, Vol. 25, No. 8 page 65. A tribute to Bob Werkowitch, former Master Brewer of Kansas City's George Muehlebach Brewing Company and graduate of the U.S. Brewer's Academy class of 1947. Bob's '47 is Boulevard's take on a traditional German-style Marzen/Oktoberfest.
Notes:
Start with 1.5 gallons of water in the brew kettle; heat to 158F. Steep the crushed malts in a mesh bag for 45 minutes, then remove. Add 5 gallons more of water, rinsing the grain bag during addition; heat to 180F. Turn off the heat. Add the malt extract, and stir thoroughly to dissolve completely. Turn the heat back on and bring to a boil. Boil the wort for 60 minutes, adding hops at the times indicated in the recipe. Adjust OG post-boil with RO water as required. Chill the wort to 50-54F, pitch the yeast, and ferment until complete. Lager at fermentation temperature (50-54F) for 2 weeks, then cool to 32-34F and cold condition for four days. If you have a spunding valve, transfer beer from primary to keg when gravity is about 1.020, close keg, pressurize to ~5 psig to seal lid, attach spunding valve, and hold at fermentation temperature (50-54F) for 3 weeks. Cool to 32-34F and cold condition for four days before serving.
