Based on the number of search engine referrals I’m starting to get from people looking for pumpkin beer recipes, as well as the flurry of Twitter chatter on the topic, I’m guessing home brewers everywhere are getting ready for fall.
I brewed a pumpkin ale last year, and it turned out pretty well. As part of the recipe, I added about 30 ounces of pumpkin pie filling from a can directly into the boil at about the 30 minute mark. It definitely darkened up the beer, which I was OK with, and you could certainly taste it in the finished product (though it wasn’t as pumpkin pie-like as some might prefer).
But this year, I wanted to switch it up a little, more for the sake of experimentation than anything. Instead of using pumpkin pie filling from a can (which I’ve since learned may not really be pumpkin at all, but rather cheaper forms of squash), I wanted to make this year’s batch as authentic as I could.
So I drove around town Saturday morning, hitting up every grocery store and roadside vegetable stand I could find in search of the gourd. Unfortunately, my efforts proved fruitless (ha!). I realized I was probably a few weeks early before pumpkin becomes more readily available, as noone had it in stock. So, I reluctantly resigned myself once again to using pie filling (100% pumpkin…I checked), but this time in the mash instead of directly in the boil to see how it impacts flavor and aroma.
However, if you do procure a pumpkin and want to prep it for the mash, you can simply cube about 5 pounds worth, lay it out on a cookie sheet, and bake the pumpkin at 375 degrees for an hour to soften the meat. Add the slightly cooled pumpkin directly to the mash along with the grains. Not sure how much fermentable sugar might be added with this method, but I’d expect fairly negligible amounts.
For this year’s version, I also opted to switch up the grain bill just a bit…I backed off the 2-row by a few pounds compared to last year’s recipe, as I didn’t want the beer to be an ass kicker in the 7-9% ABV range (I also did away with the brown sugar for the same reason). Also, instead of using Carapils to add some mouthfeel and texture, I went with oatmeal, which I thought would add a bit more interest and complexity to the beer.
Here’s the recipe in its entirety:
Mash at 152 degrees for 60 minutes
Boil volume 6.5 gallons (batch volume 5 gallons)
Target OG: 1.056 FG: 1.014 (should get it to about 5.5% ABV)
7 lb 2-row pale malt
1.5 lb Vienna malt
1 lb Munich malt
1 lb flaked oats
0.5 lb Crystal 60L
.25 lb Chocolate malt
30 oz pumpkin pie filling (not spiced, just straight pumpkin…add to mash)
2 oz Willamette (add at 60 and 15 minutes)
Wyeast 1728 Scottish Ale (1000 ml starter)
Spices (add at 10 minutes)
1 tsp ground cinnamon
1 tsp nutmeg
1 tsp ginger
1 tsp whole cloves
2 cinnamon sticks

Very interesting, I’ve never tried making a pumpkin beer before. Canned pumpkin right in the mash, how did it lauter? Did you taste the wort or sweet wort? Very curious as this is new territory to me. Can’t wait to hear how it turns out.
September 8, 2009 at 7:58 pm
Derek, the lauter went just fine…the pureed pumpkin essentially liquifies in the mash, so no issues there. Didn’t taste it, but the wort smelled rather pumpkin-like, so I’m hoping it comes through in the finished product.

I envisioned a recipe very much along these lines and I’m excited to see someone try something along the same wavelength. Happy to have stumbled upon this page. I’m glad to see you added oats, and I’m surprised to see this absent from many pumpkin ale recipes. I think the creaminess of the oats will add nicely to the character. My only modification is using 3/4-1 cup of molasses and using Perle for bittering and Fuggles for finishing. Anyway, your recipe seems solid and inspired me to try it with my own twist, although here in Phoenix I suspect I’ll run into the same “lack of real pumpkins” problem…

Thanks BioBrewer, I had some extra Willamette laying around, so that’s the main reason I went with that hop instead of something else. It just finished out yesterday, a pretty quick fermentation, and it smells fantastic, lots of pumpkin and spice.
Let me know how your recipe turns out!

So, how’d it turn out?
October 11, 2009 at 9:17 pm
I just kegged it today…aroma is fantastic, tasted pretty solid after only a couple hours of carb. I’ll give it a week or two before I review it.

Really curious to hear how this turns out! Keep us updated!

Good deal, I like this receipe as I am going to make some tomorrow for me and my clients. Oatmeal I was looking for to add in, your receipe should work. I will let you know how it turns out, thanks Scott San Luis Obispo cleaning services

Any actual pumpkin flavor in the final product? I’ve heard both sides of the coin when it comes to using real pumpkin. Some say it isn’t pumpkin ale without it, others say it just clogs the mash and you can’t taste it at all anyway.
November 20, 2009 at 11:06 am
Yep, plenty of real pumpkin flavor. My mash went fine using the puree, but I was careful to spread it out closer to the top of the grain bed, as opposed to the bottom of the mash tun to minimize clogging. I’m planning to post a review of this soon, so more notes to come. It really did turn out great.

how was it?

It turned out really well, nice pumpkin flavor and spice. My family keeps pestering me to make more of it.

So adding canned pumpkin during the boiling process for the wort is ok? Then just add all of it to the fermenter and let sit for how long?

I am actually using a pumpkin pie brew kit (with extract). But i am shooting for a butter squash beer. So i took an old country juicer, which juices fruits and vegetables with steam. I chopped up about 3 lbs of butternut squash and steamed it. Got about 2 1/2 cups of butternut squash extract, which i plan to add during the boil. But also i would like to add pumpkin pie filling (30 oz can like you said) and when i bottle i will use regular amount of priming sugar and about a 1/2 cup of lactose sugar (which is unfermentable). Then I also plan to add 2-3 drops of butter extract to about a 6-pack of the bottles. Don’t wanna take the risk of ruining a good beer with artificial flavoring but i am willing to experiment with some of it. Have you ever tried to use an artificial flavoring in a beer?
April 16, 2010 at 4:07 pm
I’ve done it both ways…adding pumpkin puree during the boil, and a can of pumpkin pie filling during the mash. The differences were negligible as far as actual pumpkin flavor. As much as many homebrewers strive to get that “true pumpkin taste”, I think the trick with pumpkin beers is getting your spices right, because that’s what most people think of when they think “pumpkin”. Straight pumpkin really doesn’t taste great, when you think about it.
I have used artificial flavors in some beers, but you need to experiment to know how much is too much, because you can quickly overdo it.

Brewing this right now! Just as you wrote the recipe but using a different but similar yeast that I used for my last brew.

I’m planning on giving this a whirl this upcoming weekend. For clarification, the canned pumpkin is added for the entire mash, right?
Shorts Brewing makes a great Nicey Spicey pumpkin ale but after tasting Arbor Brewing Co.’s spiced pumpkin stout last year in Ann Arbor, Mi I was blown away. I would love to come close to it.

Correct, I added the pumpkin directly to the mash for the entire 60 minutes. However, I didn’t just dump it all in at once, I tried to disperse it relatively evenly to prevent everything from getting stuck or gummy.

did the oatmeal flavor appear in the final product?
September 7, 2011 at 11:53 am
Not so much the flavor, but it contributed to the mouthfeel.
