Take the first gallon off the mash and put into pot on the stove. Then add 1 can of Libby Pumpkin mix to the pot and raise the temperature to 150 degrees, stirring constantly - remove from heat and put on a piece of wood or in the oven for 45 minutes, then after 45 minutes of keeping the pot temperature at 150 degrees, bring it to a boil on the stove and add it to your boil kettle with the rest of the wort. Wort will likely reach boil before pumpkin mixture so turn off burner and wait for pumpkin mixture, returning back to boiling after pumpkin addition. After boil, start hop additions and watch for hot break.
Add 1 teaspoon of pumpkin spice to the boil with 15 minutes left.
Chill to 70 degrees after last hop addition and transfer into fermenter after adding yeast. Swirl to kick off fermentation.
Add 1/3 teaspoon of pumpkin spice to the keg during transfer from the fermenter.
