Source Notes:
October 2019, Vol. 25, No. 6 page 58. This recipe is our attempt of brewing an American bock similar to that of Hartmann Brewing Co.'s 1904 version.
Notes:
Mix the grains and flaked corn with 5 gallons of water to give a mash temperature of 153 F and hold for one hour. Run off and sparge to collect 5.5-6 gallons of wort. Add the hops (and any salts, if needed, to give concentrations of 96 ppm Na+ and 148 ppm Cl-) and boil for 60 minutes. Cool to 52 F and pitch two packets of the yeast or an adequately-sized starter if using liquid yeast. Keep at 50-52 F for two weeks, by which time the gravity should be down to 1.010. Then raise the temperature to 60-65 F for two days for a diacetyl rest (not something Hartmann would have done). Then allow to cool gradually to 31 F for 20 days and put into the serving tank. Keg or bottle in the usual manner.
