Sierra Nevada Trip in the Woods Rum Barrel-Aged QuadThis classic Quad in rum barrels is a nod to the great Trappist brewers of Belgium. Deep ruby brown in color, the beer is rich and full bodied with the style's familiar dark fruit flavors, while the yeast creates a hint of spice. Rum barrels impart delicate sweetness and complexity to this beer that can be enjoyed today or cellared for years to come.
