Founders Brewing Co. (Grand Rapids, Michigan) recently sent out a teaser to inform their fans that Underground Mountain Brown will officially launch in August as the fourth release in this year’s Barrel-Aged Series.

Previously introduced as the taproom-exclusive known as Barrel-Aged Sumatra Mountain Brown, Underground Mountain is an Imperial Brown Ale that has been brewed with Sumatra coffee – roasted in Grand Rapids by Ferris Coffee & Nut – and then aged for a year in Bourbon barrels in the “caves below Grand Rapids.” Crafted to be a true “celebration of the barrel, the bean and everything in between”, Underground Mountain Brown finds harmony as the malts of the Brown Ale base “complement the bold Sumatra coffee perfectly, while time spent immersed in oak creates layers of depth and complexity.”

“We first released this beer in the taproom as Barrel-Aged Sumatra Mountain Brown and it was an immediate hit,” said Co-Founder and President, Dave Engbers. “Over the past few years, our fans have been very vocal about asking us to bottle and distribute it and we’re so happy to make it happen. The Barrel-Aged Series is a great chance for us to bring out some of these taproom fan-favorites to a larger audience and we can’t wait to hear what everyone thinks.”

Underground Mountain is scheduled to debut in Founders Brewing Co.’s Grand Rapids and Detroit taprooms on August 16 and distribution will follow later that month.  You can expect to find this Limited Release offering available in 4-packs of 12 oz. bottles, 750ml bottles and on draft at select craft beer-focused establishments located in Alabama, Florida, Michigan and throughout the rest of Founders Brewing Co.’s expansive distribution area. More info to come. Stay tuned! Prost!
