Notes: Barrel-Aged Sumatra Mountain Brown

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.

In my goblet glass, the beer looked dark brown in color at a normal viewing angle and displayed ruby highlights when held against the light. The head was under one finger thick immediately upon pour and dissipated as I typed these first two sentences. The aroma clearly showed that coffee was used during brewing. The barrels of bourbon used in aging seemed to evoke smells of vanilla, and coconut, while the malts smelled quite a bit like toffee and chocolate. The taste was pretty much a what I was smelling, but chocolate and vanilla were more prominent, and the coffee not as much. There was a pleasant alcohol warmth at the end of each sip. The mouthfeel was rich and a little oily. This beer and the Mas Agave before it has sold me big time on the Founders Barrel Aged Series. I am looking forward to the CBS next, hoping it will be available.

From tasting notes 10/20/17
Had on-tap at Founders in Grand Rapids, MI

Appearance - Served in an oversized snifter, near black with cola brown edging. Mostly barren surface with an island of suds in the center and a thin ring around the edge if the glass. Fair lacing consists of broken lines and slotting.

Smell - As with the OG, the BA has an enticing aroma. Roasted coffee, chocolate, caramel, vanilla, oak and underlying bourbon booziness.

Taste - Follows the nose. Coffee, chocolate, caramel and some bourbon qualities upfront. Bourbon holds firm throughout, adding vanilla and oak before a hint of heat bites in the chocolatey finish.

Mouthfeel - Medium-bodied with light tingly carbonation. Creamy upfront before turning a dry, slightly boozy finish.

Overall - Equally as impressive as the OG Sumatra. The BA process just adds another layer of goodness. Highly recommended if you're ever by the brewery. Hopefully they decide to add it to their Barrel Project series at some point.

Bottled 7/29/2019. Pours dark mahogany with thin tan head. Smells like milk chocolate with hints of vanilla and a faint wood character as the beer warms. Taste of sweet milk chocolate up front but quickly balanced by a nice roastiness from the coffee as well as notes of bourbon, vanilla, and wood. Since this is brown ale, mouthfeel is a bit lighter than an imperial stout, but not too light to make it thin. Overall, very enjoyable.

Pours a cloudy, deep, dark mahogany coloration with an amber hue when held up to the light and a medium, fluffy head. Smells absolutely intoxicating of roasted, slightly caramelly malt, dark, roasted coffee, milk chocolate, vanilla bourbon and oak. Taste follows the nose, with an excellent balance of of strong notes of roasted malt, coffee and bourbon, as well as some toffee, milk chocolate and lighter notes of vanilla, with just a hint of licorice and oak. Finishes with a medium bitterness and some coffee, chocolate and bourbon lingering in the aftertaste. Full mouthfeel with a medium/rich body and medium carbonation.

This is quite heavy on the roasted, bitter notes, which I quite enjoy, but also has a bit of a sharp boozy edge to it, which I enjoy a lot less but really isn't too bad. All in all a well-balanced and quite enjoyable brew that I had perhaps slightly higher expectations of though. While the interplay of roasted, bitter malt, coffee and slightly sweet toffee and chocolate notes works out quite well and there is quite a nice, perhaps slightly overdone, barrel-presence here, it's just a tad lacking in depth and richness in my personal opinion. An excellent example of the style, but not quite amazing and soesn't quite compare to Firestone Walker's Bravo.

Mahogany brown body; clear; thick and sculpted head; sticky rings and sheets of foam inside the glass. Prominent coffee waft crosses the nostrils; roasted and charred grain notes with a touch of roasted nuts. Coffee, mocha, and toffee sum up the flavor; gently sweet with a bold bitterness; chocolate. Medium-heavy body; smooth with a gentle abrasiveness; generous residual sugar presence with a noticeable dryness at the finish.

This beer brings on an incredible and thoroughly enjoyable brown ale and coffee experience. You'll experience some excellent depth and complexity here, a fine blend of sugary and sweet malts, rich and bold coffee flavors, with a thick and creamy body. Damn fine...

Always very happy to find a Founders beer on the shelf that I've never had before, and even happier of it's a barrel-aged
offering. After years of sampling beers from this Michigan brewer, I'm convinced they are the new world barrel aging masters. A little sharper than a b/a stout, a little smoother than a whiskey b/a, this one is very balanced and smooth, not to mention delicious. Thank you yet once again Founders.

I used to love brown ales in the 1990's, but the style seems to have been forgotten. I'm so glad to have found a tasty, enjoyable, engaging version of the style. The beer is a dark brown, yielding some amber hues only when held to the light. There is a slim off-white head. The aroma has lots of malt, caramel, and some nut notes. The taste is medium-dry with some bitterness and malt notes. Full in body and very rewarding. I loved this one.

Poured from bottle into a snifter
Appearance – Appropriately the beer pours a coffee colored dark brown with a head of tan colored foam. The head has a great level of retention, very slowly fading over time to leave a ton of thick foamy lace on the sides of the glass.
Smell – The aroma is big, sweet, and woody. There is a huge caramel and molasses smell that is matched by a roasted malt and a big showing of coffee. Along with these aromas comes some oak aromas and a decent showing of a ice boozy bourbon smell. The beer smells like a sweet mild brew of coffee with a couple shots of bourbon mixed within. Delicious!!
Taste – huge malty tastes of roasted malt and coffee great the tongue along with some sweeter flavors of caramel and molasses balancing them out, and producing a nice base flavor for the beer. While light upfront, the bourbon flavor really begins to amp up as the taste moves forward on the tongue, getting quite delightfully boozy more toward the finish of the taste. At the same time some oak and char along with an earthy hop also comes to the taste accentuating the bourbon flavors quite well. While so, more caramel and a bit of an almost creamy like taste come to the tongue and leave one with a robust boozy roasted coffee flavor to linger on the tongue.
Mouthfeel – The body of the brew is somewhat chewy with a carbonation level that is lower. The lower carbonation accentuates the chewy and thicker feel and really allows the big boozy and sweet coffee flavors to be savored.
Overall – This is one big and robust sipper for sure. Dark, sweet and very robust. A very nice nightcap on a cool fall day!!
