Underground Mountain Brown

Imperial Brown Ale Brewed with Coffee and Aged in Bourbon Barrels

2019 ABV:
RateBeer Rating:

Underground Mountain Brown is the harmonious drinking experience only achieved when our imperial brown ale, earthy Sumatra coffee and a year aging in caves below Grand Rapids come together. A team of malts complement 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.

“It’s up to us to really diversify, we can’t just be limited to stouts… we have to push that envelope. You put the right beer in the right barrel and you’re going to create some pretty interesting flavors…” – Jeremy Kosmicki, Brewmaster
