Goose Island Bourbon County Brand Reserve Stout is a limited-edition barrel-aged imperial stout from Goose Island Beer Co., brewed in Chicago, Illinois. This premium release is aged for two years in Parker's Heritage Collection bourbon casks, developing concentrated layers of cocoa, dried fruit, spice, and toasted oak. The deep, complex flavor profile features rich notes of dark chocolate, toffee, caramel, vanilla, and bourbon, culminating in a smooth, full-bodied beer with a warming finish.

This Costco exclusive pack includes 12 bottles at 16.9 oz (500 mL) each, with a 14.5% ABV. Due to the highly limited nature of this release, purchases are restricted to one pack per Costco membership. Bourbon County Brand Stout is widely regarded as one of the pioneering American barrel-aged stouts and remains a highly sought-after annual release among craft beer enthusiasts.
