Mill the grains and add the pumpkin puree, then mix with 6.25 gallons (23.7 L) of 163 °F (73 °C) strike water to reach a mash temperature of 152 °F (67 °C). Hold this temperature for 60 minutes. Vorlauf until your runnings are clear, and lauter. Sparge the grains with 1.5 gallons (5.7 L) and top up as necessary to obtain 6 gallons (23 L) of wort. Boil for 60 minutes, adding hops according to the ingredient list and Irish moss if desired. After the boil, chill the wort to slightly below fermentation temperature, about 66 °F (19 °C). Aerate the wort with pure oxygen or filtered air and pitch yeast. Ferment at 67 °F (19 °C) until wort reaches 1.028 specific gravity, then free rise to 72 °F (22 °C) until the completion of primary fermentation. Once the beer completes fermentation, reduce temperature to 32 °F (0 °C) and hold for 10 days. Draw a sample, and add spice extracts to taste, starting with a ratio of approximately 3:1 for the cinnamon to other extracts. Once the exact ratio/intensity is determined, scale up and add to the fermenter. Then bottle or keg the beer and carbonate to approximately 2.25 volumes.

End Spice Notes: The common pumpkin pie spices are; Cinnamon, Nutmeg, Allspice, and Ginger. Add just one teaspoon of the spice blend to the boil in the last ten minutes. It is very easy to overpower a beer with these spices, and it is easier to add more than take some out. Fine-tune the spice level at bottling and enjoy!
