ahhh whoa old thread -
The beer came out pretty good. The wheat added a nice smooth and bready flavor to the beer which went very well with the pumpkin flavors. I would change a few things however - Up the IBUs to mid 20's and eliminate the 30 minute hop addition.
As far as the grain bill goes, I would recommend adding some kind of crystal/amber malts to the mix (cutting back on the carapils) to add a bit more complexity and sweetness. If I recall, this beer finished around 1.011-1.012... a little lower than expected.
The spices were very prominent in this beer. I would cut them by about half. Also, I would just mix all of them up, throw 2/3 of them in the boil at FO. Then, when it's time to keg or bottle throw the remaining 1/3 spice mix. I recently just did this spicing technique with a rye pumpkin ale and it produced outstanding results.
Also, be sure to use RICE HULLS. With all the pumpkin and wheat use at least half a pound.
