Founders Underground Mountain Brown will be the 4th release in the brewery’s Barrel-Aged Series this August.
Brewery fans know this beer under a different name, Barrel-Aged Sumatra Mountain Brown. Founder takes an imperial brown ale, adds Sumatra coffee, and ages it in bourbon barrels in their caves for nearly a year. This release follows new margarita-inspired Mas Agave, presumably on shelves now.
A team of malts complements the bold Sumatra coffee perfectly, while time spent immersed in oak creates layers of depth and complexity. A celebration of the barrel, the bean and everything in between.
Founders Underground Mountain Brown will be available in 12- ounce and 750-milliliter bottles, as well as draft, starting in mid-August.
11.9% ABV, 30 IBUs
