Spiced Pumpkin Ale
My friend Michael has come back to brew another batch of beer with me. His interest in brewing has really grown, and while in the process of buying equipment with his friend Christian, he's getting the feel for it in the meantime. For this one, he wanted a more malty sweet brew, and after reading an article in Zymurgy (Nov.-Dec. 08) about brewing pumpkin ales, he wanted to go with the all-grain recipe published there.
I ordered all the malts, and stuck with the recipe for the most part. Since he already had Hallertau hops, he simply substituted them for the Fuggle. I put him in charge of roasting the pumpkin with a sugar glaze. With freshly grated ginger and spices, and a super rich malt base, this beer should turn out super smooth with a fresh pumpkin pie spiciness that should warm the soul during the coldest time of year.
Two things will be firsts for me brewing this beer. First, I've never used White Labs yeast before, but the scents from it's starter were very much like Wyeast British Ale, and it has super dense flocculation (the ability for yeast to settle out in a soft to hard layer after fermentation). Second, I've never used a vegetable as a key ingredient before. In fact, I was telling Michael how much I looked forward to brewing this, especially because I've wanted to make a true pumpkin ale for three years now. This looks like a solid recipe, and I can't wait to taste the results.
Just like the article suggests, it was a real pain straining through the funnel filter screen. Pour after pour, topping off the funnel, we had to take turns stirring, scraping and squeezing the pumpkin mush at the screen, preventing hand cramps. We literally had to do this for the whole batch.
During the beginning of an all-grain full wort boil, there is a lot of foam that builds up. It's generally good to let it boil for 10-20min before adding the bittering hops. Some worts foam up more than others. This pumpkin wort had the most foam I've ever seen, and it took a while before it subsided. I have a feeling it's due to starches in the pumpkin. It became a mess at times, but it smelled fantastic...sweet pumpkin and rich malts...Mmmm!
In the end, the wort smelled very good...sweet with a soft pumpkin pie spice. We added a couple more spices to the mix, but at a level that isn't overbearing.
