The name Underground Mountain Brown hearkens back to the year it spent aging in bourbon barrels in the caves below Grand Rapids. The malts used in the brown ale really let you experience the earthy flavors and nuances of the Sumatra coffee. If you've been missing Sumatra Mountain Brown this beer should fill that void in your heart.
