A seasonal American ale — typically fall-released — brewed with pumpkin (or other squash) and/or “pumpkin pie” spices: cinnamon, nutmeg, allspice, clove, ginger. Typically 5.5–8% ABV, amber to copper. The base beer is usually a moderate amber ale, brown ale, or spiced autumn ale. Pumpkin flesh contributes subtle earthy-vegetal sweetness; the warming spice bill is typically the more prominent flavor driver.

Origin
Pumpkin beer is an American original, born in the colonial era when settlers turned to a plentiful New World crop to stretch scarce barley. Pumpkin is rich in starches and sugars, and early colonists pressed it into service as a fermentable. The oldest known recipe for “pompion ale,” published anonymously in 1771, calls for nothing but boiled and skimmed pumpkin juice, hopped, cooled, and fermented like malt beer — closer to a pumpkin wine than to anything brewed today. Later recipes folded in malt, moving the drink toward the modern version. The contemporary revival is usually credited to Buffalo Bill’s Brewery of Hayward, California, which brewed its first batch in 1985 — initially sold as Punkin Ale and renamed Pumpkin Ale the following year — and is widely regarded as the first modern commercial pumpkin beer. Dogfish Head’s Punkin Ale, first entered into a Delaware pumpkin festival’s baking contest in 1994 and released commercially the next year, helped carry the style to a national audience. Pumpkin beer expanded enormously as a fall seasonal through the 2000s and 2010s before cooling somewhat late in that period, though it remains a fixture of the autumn shelf.
Notes
In practice the spice bill — cinnamon, nutmeg, allspice, clove, and sometimes ginger or vanilla, the same warming blend associated with pumpkin pie — usually drives the flavor more than the squash itself, which contributes a subtle earthy sweetness. The strong association between pumpkin and the holiday pie has shaped how the style tastes, and the best examples integrate the spices rather than letting cinnamon or clove run away with the beer. Approaches vary: some brewers add actual pumpkin to the mash or kettle, others rely on the spice blend alone. Imperial pumpkin ales such as Southern Tier’s Pumking push the style into high-gravity territory near 8.6% ABV. Most arrive in late summer, an annual harbinger of the coming autumn.
