Founders Brewing Co. announced today that Underground Mountain Brown will return to the brewery’s 2020 Barrel-Aged Series lineup.
First launched in 2019, Underground Mountain Brown is a barrel-aged version of the brewery’s since-retired imperial brown ale, Sumatra Mountain Brown.
Underground Mountain Brown contains an array of malts that complement the Sumatra coffee, the brewery says, while time spent in oak creates depth and complexity. The Sumatra coffee is roasted in Grand Rapids by Ferris Coffee & Nut.
“Underground Mountain Brown is a fantastic example of our use of coffee in beer-making,” says Brewmaster Jeremy Kosmicki. “Using an imperial brown ale as a base for the earthy and rich Sumatra coffee allows the coffee flavor to shine while adding the perfect complement of sweetness. Add in the extra layer of depth from barrel aging and you get an extremely complex yet approachable beer.”
Underground Mountain Brown (11.9%) will be available in both the Grand Rapids and Detroit taprooms beginning on Sept. 2, and will start shipping later that month across the distribution network, except for MS. The suggested retail price is $15 per 4-pack. The beer will also be available on draft, and in 4-packs of 12-oz. bottles. Pricing varies by market.
Underground Mountain Brown is preceded by Más Agave, Más Agave Grapefruit, KBS Espresso, KBS and Backwoods Bastard in the brewery’s 2020 Barrel-Aged Series. There is one more release in the 2020 series that’s yet to be announced.
