After mashing the pumpkin in last year's pumpkin ale, and getting a super sticky mess of a sparge, I decided to only boil pumpkin this year. I used 3 lbs of baked, canned pumpkin in the full boil, spices added over the last ten mins. The whole boil smelled of wonderful pumpkin and once the spices went in, the aromas were delicious pumpkin pie. The wort sample tasted like a very very sweet pumpkin pie. Plenty of pumpkin and
pie spice flavor and aroma.
From what I gathered by boiling a pound of canned pumpkin in a gallon of water was that the pumpkin contributed ~4-6 gravity points. I also took readings on brew day, one from the runnings before the pumpkin went in, one right after adding and stirring in the pumpkin. 3 lbs added ~4 points to ~6.5 gal of wort. YMMV
I'll be taking the first final gravity reading this weekend, I'll try to post my results back here, but you can follow this thread
to see how it comes out.
