Next year, plan on brewing your pumpkin ale in June/July. A pumpkin ale may be drinkable 31 days after brew day, but from my experience, all of my pumpkin ales don't PEAK until about 3-4 months conditioning.
I made mine this year on June 23 and served it at a festival last weekend, and it tasted like a commercial beer.
