Founders KBS Blueberry is a Double Coffee Stout by style. It’s time to celebrate two decades of barrel-aging imperial stouts with KBS Blueberry. In honor of the 20th anniversary of KBS, we’ve given this legendary beer a dose of Michigan blueberries. The alluring aroma of dessert brings you in, while layers of vanilla, coffee, chocolate, oak and bourbon barrel notes become more profound with every sip. A sweet and sophisticated tribute to a world-renowned beer. This beer is 11.2% ABV. In this beer review, we will looak at the color, smell, and taste.
