Boulevard Bourbon Barrel Aged Quad 4Pk is a four-pack of 12 oz bottles featuring an 11.8% ABV Belgian-style quadrupel aged in bourbon barrels from Kansas City's Boulevard Brewing Company. Earning a 94 score on BeerAdvocate across nearly 2,900 ratings, this barrel-aged quad ranks among the most consistently praised American interpretations of the Belgian abbey tradition. Quick Facts: ABV: 11.8% | Origin: Kansas City, Missouri | Style: Barrel-Aged Quadrupel | Brewery: Boulevard Brewing Company Production & Heritage Boulevard Brewing Company, founded in 1989 in Kansas City, Missouri, built its reputation on approachable ales before expanding into the ambitious Smokestack Series, which includes this bourbon barrel-aged quadrupel. The base beer draws from Boulevard's abbey-style quad recipe, then spends extended time—sometimes up to three years—in oak bourbon barrels sourced exclusively from Holladay Distillery, also based in the Kansas City area. During barrel aging, cherries are added to compensate for the liquid lost to evaporation (the "angel's share"), and individual barrels are then carefully blended for optimum flavor balance before packaging. Tasting Notes Aroma: Rich caramel and toffee dominate the nose, followed by pronounced bourbon and vanilla oak. Dark fruit emerges underneath—fig, plum, and a subtle thread of cherry-tinged pipe tobacco. Taste: The entry is sweet and bread-forward, with brown sugar and caramel coating the palate immediately. Mid-palate introduces bourbon warmth alongside dark fruit notes—cherry, plum, and dried berries interweave with vanilla-infused oak. The sweetness stays controlled despite the intensity, never tipping into cloying territory. Finish: Long and warming, with lingering bourbon spice and oak-driven richness. Toffee and dark fruit fade slowly, leaving a dry, subtly tannic close. How to Drink Boulevard Barrel Aged Quad Serve at cellar temperature (50–55°F) in a tulip glass or snifter to concentrate the complex aromatics; a short rest in the glass after pouring allows the bourbon barrel character to open up fully. For a Boilermaker, pair a small pour of straight bourbon alongside the quad—the shared barrel DNA creates a seamless bridge between beer and whiskey. A dessert-style Beer Float with high-quality vanilla bean ice cream plays beautifully off the toffee and vanilla oak notes. It also works in a traditional Flip, shaken with a whole egg and a touch of demerara sugar for a rich, frothy after-dinner drink.

Why Boulevard Barrel Aged Quad? Few American breweries have committed to barrel-aging a Belgian quadrupel with the consistency Boulevard has maintained here. The exclusive use of Holladay Distillery bourbon barrels—sourced from a fellow Kansas City producer—gives this beer a regional identity that generic barrel programs lack. The addition of cherries during aging to compensate for the angel's share, the extended barrel rest of up to three years, and careful blending of individual barrels result in a layered, warming ale that stands apart in a crowded barrel-aged market. A 94 on BeerAdvocate from thousands of independent drinkers confirms what the glass already reveals: this is one of the benchmark bourbon barrel quads in American craft brewing.
