Ingredients Overview

The essential ingredients include fresh pumpkin or pumpkin puree, malted barley, hops, ale yeast, and clean water, with optional spices like cinnamon, nutmeg, and brown sugar. Your base malt does the heavy lifting. You’ll want to utilize 6 to 8 pounds of pale malt or amber malt, which forms the foundation of your beer, bringing those bready, toasty notes that support all the other flavors. You don’t really want any hop flavor or aroma in your pumpkin beer, so choose a clean hop like Magnum. 

For balance, use 1 to 2 ounces of Cascade or Centennial hops. You only need a bittering dose, not quite 20 IBUs’ worth, to keep the malt sweetness in check. Select a good quality ale yeast, such as American Ale Yeast like Safale US-05 or Wyeast 1056. For spices, add 1 to 2 teaspoons of cinnamon, nutmeg, or allspice to enhance the pumpkin flavor. 

Optional additions include 0.5 to 1 pound of brown sugar for added sweetness and richness, 1 tablespoon of vanilla extract during fermentation, or oak chips soaked in bourbon for unique depth.

Choosing a Base Style

The beauty of pumpkin beer brewing lies in its flexibility—you’re not locked into a single style. A pumpkin beer recipe can start with multiple base beer styles, and each foundation brings something different to the party. Think of the base style as the canvas you’re painting your autumn masterpiece on.

Traditionalists will add pumpkin to a pale-colored, lightly-hopped ale comprised primarily of American-grown 6-row malt. This classic approach lets the pumpkin and spices shine without competing flavors. Honey and maple syrup may also be used, as they were popular fermentable substitutes used to replace inaccessible grains during colonial times, adding historical authenticity to your brew.

Want to go darker? Darker, roastier styles like stouts, porters, and browns lend themselves well to the spices that accompany pumpkins in pie or other dessert dishes. The higher Lovibond specialty malts that create the robust flavors and dark hue make for a heftier malt backbone that can stand up to more aggressive spice additions. The roastiness of porter or stout makes an excellent complement to the spice regimen.

Looking for something unexpected? There are even Belgian styles, in which the esters from the yeast meld with the pumpkin to create a unique, yet delicious experience. Yeast that creates clove and ginger qualities can be artfully used to mimic cooking spice additions that complement the pumpkin.

The grain bill should have a strong malt backbone to support the pumpkin and spices and let the orange color shine through. Whatever style you brew, the goal should be balance—showcase the pumpkin and spices without overpowering the base style, but ensure the flavors are present.

Choosing the Right Pumpkin

If fresh pumpkin isn’t available, canned pumpkin is a perfectly suitable substitute. However, avoid products that list any ingredients other than pumpkin, like preservatives, and don’t use products referred to as pumpkin pie mix or filling, which usually include spices, sugars, and very small amounts of actual pumpkin. Libby’s 100% Pure Pumpkin is pure pumpkin with nothing added—it’s all-natural, gluten-free, with no GMO ingredients.

For fresh pumpkin, selection matters. Traditional Halloween jack-o’-lantern pumpkins aren’t the best choice as they provide minimal flavor and fermentables. Use pie pumpkins or sugar pumpkins for the best flavor and texture.

Tips for choosing fresh pumpkins:

• Look for small pumpkins weighing 2-3 pounds and measuring 7-8 inches in diameter
• Consider crookneck pumpkin, also known as neck pumpkin, which has a deeper flavor
• Select pumpkins with dense, sweet flesh rather than watery varieties
• Slice pumpkins in half, remove seeds, sprinkle with brown sugar (8 ounces per 5 pounds), and bake at 400°F for about an hour until soft
• Save all juices produced during baking to add to the boil

Brewing Process Step-by-Step

1. Before starting, clean all equipment thoroughly to prevent contamination. You’ll need your homebrew kettle, fermenter, and wort chiller. Once the pumpkin is cooked, mash or puree it to incorporate into the wort.
2. Bring about 2.5 gallons of water to a boil, add malted barley, stirring gently, and maintain a boil for 60 minutes. If adding pumpkin to the mash, use 3-5 pounds per 5-gallon batch. Be aware that putting pumpkin in the mash will result in a long brew day, and pumpkin can cause a stuck mash. Adding rice hulls helps prevent flow issues.
3. After 45 minutes of boiling, add hops for flavor and bitterness. Stir the pumpkin puree into the boiling wort, allowing it to integrate for the remaining 15 minutes. For fresh pumpkin, add the pumpkins and extra juices at 30 minutes before the end of the boil, preferably in a mesh bag to keep the pumpkin contained and prevent clogging valves.
4. After boiling, cool the wort quickly using an immersion chiller or an ice bath for efficient cooling, then transfer to your fermentation vessel, leaving sediment behind and ensuring you have some headspace. Sprinkle ale yeast on top of the wort and seal the fermenter.
5. The initial gravity should be around 1.047, and you should let the temperature free-rise to 67°F as fermentation starts, holding at 67°F for 5-7 days until primary fermentation is complete, then letting the temperature free-rise up to 72°F to finish fermentation. Fermenting at 72°F to 74°F seems to give a better flavor profile, perhaps from increased ester production.
6. Once fermentation slows, siphon the beer into clean bottles, add priming sugar to carbonate your beer, and cap the bottles securely. Allow bottles to condition at room temperature for about 2 weeks, then move them to a cooler place for a few days before chilling and serving. Pumpkin ale takes about a month of conditioning to hit its peak.

Spices & Flavoring

Spices are as important, if not more so, than the pumpkin itself, and in many instances, recipes rely on spices used in pies to create the sensation of drinking pumpkin pie. They make the pumpkin ale come alive, taking the place of traditional flavor and aroma hops.

Vanilla, allspice, ginger, cinnamon, nutmeg, and cloves can all be used. For a 5-gallon batch, add 3.5 teaspoons of cinnamon, 3/4 teaspoon of nutmeg, and 3/4 teaspoon of ginger. Don’t be afraid to get a little aggressive with the spices, as the right dose does wonders for this style, though being too conservative could leave you with a somewhat bland beer.

Timing matters significantly. Spices are typically added at the end of the boil and/or before bottling to help preserve the flavors and aromatics. Adding spices with 30 or fewer minutes left in the boil preserves flavor and aroma, as adding before this will boil them away.

If adding before bottling or kegging, it’s recommended to make a spice extract with a neutral, high-gravity spirit as a sanitary measure, then add small increments of the extract to taste. You can always add more spice, but it’s much harder to take it out.

Quality matters. The good stuff—gourmet cinnamon, freshly ground nutmeg, and ginger—costs a mere pittance more, but the flavor blows away the cheap stuff. Saigon cinnamon is preferred for its strong, rich, and sweet flavor, and imitation vanilla is vile and can’t compare to pure vanilla extract.

Common Mistakes to Avoid

• Over-spicing: Cloves in particular contain an oil that numbs the taste buds, and nutmeg contains the same oil while being potent and sweet, so both should be used sparingly. Cloves always seem to be the spice that throws things out of balance. If you’re squeamish about the amounts, add the spices gradually—tasting along the way—until you achieve the flavor you want.
• Poor temperature control: Fermentation temperature impacts flavor, so neglecting temperature control is a major mistake. Maintain a steady temperature of around 68°F to 72°F during fermentation for optimal results.
• Stuck mash: Pumpkin creates the perfect storm for a stuck sparge. Add rice hulls to improve flow, and consider performing a protein rest at 120°F for the first ten minutes of the mash.
• Rushing fermentation: Even though primary fermentation will be complete in a few days, wait at least a week before racking to a secondary fermenter, and the secondary phase lasts another week or two.
• Improper pumpkin amounts: Balance is critical—use approximately 1 pound of pumpkin per gallon of beer to avoid an overly dense or underwhelming result.
• Using low-quality spices: Some brewers commit hours of work to brewing and then ruin their masterpieces by adding dollar-store quality spices.

Serving & Pairing Ideas

When beers are served slightly warmer, they tend to have more pronounced aromas and flavors, which are ideal when serving pumpkin or late harvest beers. Following the traditional rule of serving darker beers slightly warmer (around 45-50°F) and lighter beers colder (38-45°F) can dramatically impact how flavors develop on your palate. The pumpkin beer style pairs well with fall food flavors like roasted turkey and coffee ice cream, and Camembert cheese is another decadent beer pairing. Pumpkin beers pair well with dishes like chicken pot pie, roasted root vegetables with wild rice, spicy curry, mac and cheese, or pork tenderloin. A mild, not too sweet pumpkin beer is the best choice for pumpkin pie.
