Founders KBS Blueberry 4Pk is a bourbon barrel-aged imperial pastry stout brewed with Michigan blueberries, coffee, and chocolate at 11.2% ABV. Released to mark the 20th anniversary of the original KBS — the first beer Founders ever barrel-aged — this variant scored 91 on BeerAdvocate, earning widespread recognition among barrel-aged stout enthusiasts.Quick Facts: ABV: 11.2% | Origin: Grand Rapids, Michigan | Style: Bourbon Barrel-Aged Imperial Pastry Stout | Brewery: Founders Brewing CompanyProduction & HeritageFounders Brewing Company, based in Grand Rapids, Michigan, built its national reputation in large part on KBS — Kentucky Breakfast Stout — which debuted as the brewery's very first foray into barrel aging. The base imperial stout is brewed with coffee and chocolate, then aged in bourbon barrels where it picks up layers of vanilla, oak, and bourbon character. For this anniversary variant, the brewers introduced a dose of Michigan-grown blueberries into the barrel-aged stout, adding a fruit dimension that distinguishes it from other expressions in the KBS lineup.Tasting NotesAroma: Rich bourbon barrel character leads, layered with roasted coffee, dark chocolate, and a subtle undercurrent of fresh blueberry. Vanilla and brown sugar emerge as the beer warms in the glass.Taste: The entry is full-bodied and sweet, with milk chocolate, toffee, and a concentrated blueberry tang that develops at mid-palate. Coffee bitterness stays restrained, letting bourbon-soaked oak and currant-like fruit flavors share the stage. The interplay between blueberry sweetness and roasted malt deepens with each sip.Finish: Long and viscous with a smooth, oily texture. Lingering notes of vanilla, dark fruit, and barrel char fade slowly, leaving a warming bourbon impression.How to Drink KBS BlueberryPour into a snifter or tulip glass at cellar temperature (50–55°F) to fully open the barrel and fruit character; avoid serving ice-cold, which mutes the complexity. This stout is best enjoyed on its own as a sipping beer, but it also shines in beer-forward mixed drinks: a Bourbon Barrel Float using a scoop of vanilla bean ice cream accentuates the chocolate and blueberry notes; a Stout Flip (whole egg, simple syrup, nutmeg) highlights the creamy body; and a Black Velvet riff topped with a small measure of dry sparkling wine adds effervescence that cuts through the richness.Best For Gifting a craft beer collector who hunts limited barrel-aged releases Capping off a multi-course dinner as a dessert beer alongside chocolate or berry tarts Vertical tastings comparing KBS Blueberry against the original KBS and other KBS variants Celebratory occasions that call for a high-ABV sipper with presence and complexity Frequently Asked QuestionsWhat does KBS Blueberry taste like?
