This weekend I brewed for the first time in months (still recovering from reconstructive surgery on my ankle) and it was only the second AG batch I have ever done.
I figured a pumpkin ale would be nice to age out for a few months, and a nice simple Ale with Pumpkin added would be hard to screw up so I was a bit more comfortable with my less-than-perfect AG system. The wort literally tasted like liquid pumpkin pie (I kinda drank the hydrometer test wort post-grav reading

) and had an incredible color to it.
Below is the recipe I used, pulled from the Nov/Dec 08 Zymurgy issue. Only modifications I made were 1) Safale 04 yeast x 2 and 2) an extra 1.5 pounds of canned pumpkin.
I also added a bit if cinnamon, brown sugar, crushed cloves and nutmeg to the pumpkin and roasted it for about 4 hours. The whole house still smells like pumpkin pie!
The original brewer (Mark Pasquinelli of PA) recommended slightly less carbonation, and suggested about 3.5 cups of priming sugar.
