Underground Mountain Brown

Brown Ale - Imperial / Double

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 comes 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.

Amazing stuff, Sumatra is one of my favorite coffees, marry that with aging in oak & this stuff is the bomb. Coffee on the nose & on the tongue. Super smooth silky follow through & finish. I am in love. No give away that it's almost 12% ABV.

Супер. Это настоящий имерец с годичной выдержкой в бочках из под бурбона! Сварен с кофе. Последнее почти не чувствуется , но добавляет богатство оттенков во вкусе. В ароматике явно копчёность.

Man. Arguably my favorite Founder’s next to the backwoods. Tested negative for COVID so why not have a beer?

#30,round 10. Only reason this was around so late is because it was a clone. Aged in bourbon barrels & a double imperial Brown with HIGH ABV. Charred malt, Sumatra coffee beans, and Derek, it doesn't taste boozy. Thanks Shawn. My beer draft 6 favorite

So I yelled, "Hey Brian Sever, I'm not going to put up with your jingoistic approach to social dadaism In a Kafkaesque patriarchy in our 21st century geodome." And that's the thing about a Gloucester bar. As soon as I said it everyone had my back.

Still holding up nearly 16 months after bottling. Bitter coffee with a nutty, roasty, and chocolately brown undertone. Tons of caramel and vanilla from the bourbon lingers well after the finish.

A perfect brown ale, and a style that is greatly under produced. Reminds me of a fudge brownie with caramel drizzle and a hint of bourbon spices!

Wonderful rich bourbon and coffee with deep roasted raisin brandy and caramel boozyness. Smooth oak barrel tannins and cocoa dryness that cuts the sweetness nicely and avoids any syrupyness
