KABOOMQuaff Bros. KABOOM! is an Oatmeal Stout that has been soaked and saturated in Bourbon barrels with the addition of cinnamon to give an almost candied red hot flavor component that lingers on for days. These aren’t just any Bourbon barrels that KABOOM! was aged in, they once held a very special and un-mistakenly famous 23 year old Bourbon distilled by Buffalo Trace (use your imagination). KABOOM! is a near perfect mesh of savory nuances. You will find the robustness similar to a cup of fresh “joe”, along with smoky and gamey flavors all intertwined together with notes of caramel, molasses and vanilla that dial out to a long spicy and boozy finale.
