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.

Delicious. Goes down way too easy for a 12% imperial on a Sunday night.

Pours dark brown with creamy tan head. Smell is primaily roasted coffee, bourbon, with hints of chocolate, & caramel. Taste is primarily bourbon, followed by espresso/coffee with hints of chocolate & brown sugar, & finishes with bourbon again. Excellent!

All I can say is wow! What a great beer! This barrel aged imperial brown ale was barrel aged in a cave below Grand Rapids MI. Bold and with a big coffee punch it is great for a cold fall night!

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.

#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.
