Founders Brewing Co. (Grand Rapids, Michigan) has officially announced that Underground Mountain Brown will be back for an encore release in the brewery’s Barrel-Aged Series in early September 2020.

First introduced last year as a part of Founders Brewing Co.’s 2019 Barrel-Aged Series lineup, Underground Mountain Brown is a “barrel-aged version of the brewery’s since-retired Imperial Brown Ale, Sumatra Mountain Brown.” Clocking in at slow-sipping 11.9% ABV, Underground Mountain Brown allows its team of malts [to] complement the bold Sumatra coffee perfectly while time spent immersed in oak creates layers of depth and complexity.”

“Underground Mountain Brown is a fantastic example of our use of coffee in beer-making,” said 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.”

The 2020 batch of Underground Mountain Brown will hit Founders Brewing Co.’s Grand Rapids and Detroit taprooms on September 2 and distribution is scheduled to begin later that month. You can expect to find this Limited Release available in 4-packs of 12 oz. bottles and on draft at select craft beer-friendly establishments located in Alabama, Florida, Michigan and throughout the rest of the brewery’s nationwide distribution network (except Mississippi). Prost!
