Swamp Stacks is a mashup of our Shades and Great Notion’s Stacks series. This Imperial stout is brewed with brown sugar and an array of specialty roasted malts, creating a warm, decadent final product. With post-fermentation additions of maple, marshmallows, graham crackers, and toasted coconut flakes, Swamp Stacks exudes waves of maple coconut chocolate squares and boozy brown butter blondies.⁣
