I put 2 cans pumpkin in boil. At flameout. Add 1/2 tsp each cinnamon, nutmeg, and all spice. Very lightly spiced allowing delicate pumpkin to shine through. This recipe is legit, i have made it every year for thanksgiving 4 years in a row now. Cheers.
Most people would say amber or brown or maybe a stout. I make a marzen pumpkin spice beer and roast coffee and add that after fermentation. Makes a nice Pumpkin Spiced Latte Oktoberfest that I named Basic Bitch lol.
Imo and based on stuff i have read, pumpkin has a very slight flavor. Haha dont want to say delicate for pumpkin, but yeah. For a porter, or coffee pumpkin, i think the pumpkin pie spices are more the associated flavors and i would be tempted to not even add pumpkin. Or would add it just to say i did. Brulosophy, i think it, was did a triangle test that hinted that the p spiced beer with or without pumpkin tasted the same. Just some food for thought i guess. I make mine so i can drink it all day and not get sick of it. Very lightly spiced.
