Source Notes:
September 2019, Vol. 25, No. 4 page 103. A beautifully toasty dark lager with just enough malt to make you feel enveloped...but not overwhelmed. It's the ideal showcase for great Munich malt. Some folks say it's an old man's beer and you should be enjoying a helles or Pils, but I'll take a dunkel any day thank you very much.
Notes:
This is a single infusion mash. Heat 16.7 qts of water, add 1 tsp. of calcium chloride. Mash grains for 60 minutes at 152 F. Sparge with enough water to collect 6.5 gallons of wort in the kettle. Bring wort to a boil and boil for 60 minutes, adding hops as indicated. Add a kettle coagulant of your choice if you so desire. After the boil is complete, give the wort a long stir to create a whirlpool and let settle for 10 minutes, then begin to chill. Bring down to yeast-pitching temperature, aerate the wort, and pitch the yeast. Fermentation temperature can vary depending on your fermentation control. You can ferment from about 55-65 F. Ferment for 1-2 weeks at this temperature. Transfer to a secondary and lager for 1-4 weeks at 33-35 F. Bottle or force carbonate per normal.
