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. When formulating an extract version of the all-grain recipe Old Timer's Bock, we had to make some sacrifices due to the large percent of flaked corn in that recipe. As such, this recipe will end up different (the reason for it getting a different name), but still very tasty.
Notes:
Dissolve the malt extracts in warm water to give a final volume of 5.5 gallons and then bring to a boil. Once a boil is reached, add the hops (and any salts, if needed, to give concentrations of 96 ppm Na+ and 148 ppm Cl-) and then boil for 1 hour. 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.
