Needed a cork screw for this one since the beer is close to dead flat but thats seriously not a problem. The beer is super intense with big notes of cocoa and licorice on the nose. Subtle nuances of smoke and leather. The mouthfeel is super full and super silky with an incredible amount of layers. Sweets, savory, richness, but manages to stay clean the entire time. Smooth rounded finish that lasts and lasts and leaves the mouth watering. Simply and incredible beer.

Bottle purchased at Nathaniel Square Corner Store.

Pours a deep, dark inky black, with a small half-inch head, and a not much lacing.

Smells like chocolate, coffee, hazelnut, roasted malt, and a small amount of booze.

This has just a wonderful chocolate flavor to it, like rich melted Belgian chocolate, with hazelnut, nutty roasted coffee, roasted malt, raisin and other dark fruit flavors, and a small amount of bitter booze, which is ok- this one's 11%.

This one has an insanely creamy mouthfeel, almost milk-shake like, with an appropriately low amount of carbonation (I've heard it could be too high in the past). It's fairly thick bodied, and very drinkable.

This is a great little brewery from Brazil, and I will be on the lookout for more beers from them in the future.

What an incredible display of stout flavor. Nestled in the deep South American landscape, the artistry and culinary art in ale is certainly not lost on the Wäls brewery- its English "Russian" character is alive and well while its viscosity and intensity is much more suggestive of massive modern stout.

And like petroleum, the beer's dirty motor oil appearance is an understatement. Opaque and onyx-like, the ominously black beer patiently sheds a froth that's the stuff of mocha meringue. Fresh roasted coffee, dark chocolate and grilled fruit fill the nose with a cognac-like alcohol tinge. But with the first taste being equally robust and savory, the burnt sugars of black-strap molasses, brown sugar, toffee and maple line the tongue with absolute saturation.

And a whole host of roasted flavor opens up on the tongue when the roasted, creamy and savory malts splash the senses to completion- Those wonderfully burnt sweetnesses latch onto every tastebud and is slow to release. Delivering the scorched earth character of espresso, bitter baker's chocolate, charred walnut and a light woodsy campfire aura giving a nod to turkish coffee. Its lasting taste is one of grilled currant, red grape, blueberry, blackberry and cherry- all seeming bathed in fortified cognac.

Ridiculously full and lavish, the beer's silky pattern is broken only buy its enormous strength. Spicy cognac offers a boozy dryness, vinous and peppery character to balance the sweet and to add complexity to the roast. Still, the beer's warming sensations march deeply in aftertaste with cocoa and coffee.

This is petroleum. Or maybe old engine oil. Anyway, very dark liqueurish beer, with a dark brown head that easily dissipates. Distinct cocoa notes, hence dark chocolate (of course, it's maturated with belgian cocoa), and a few sweet yiest notes that balance the whole. Despite the fact that it's a 70 IBU Stout, this beer doesn't show a huge bitter mouthfeel effect, which is counterbalanced by the forementioned sweet notes. It's a full-bodied beer, as one would expect, which confirms its molasses appearance, and it has some toffee toasted notes, a gift-cliché from Stout style beers. Lingering finish with astringent qualities. Look forward to tasting another Wäls beer.

Beer of beautiful appearance, of a deep and dark black color and a browny foam.
Smell is really good, and very strong, full of roasted malts, chocolate and coffe notes.
Taste is similar, but not as pleasure as the smell.
ABV and IBU are really high, but hidden in the full body of this beer.
Yeah, really good.

Under-rated beer in my opinion. Viscous chocolatey coffee flavors in this beer. Some molasses notes as well. Never gets boring; flavors just keep coming strong.

This beer is the result of a collaboration between a group of Homebrewers (Dum cervejaria) that developed the recipe and the Wals Brewery from Belo Horizonte, Brasil that finally brewed and released it on a large scale.

It's an Imperial Stout with a huge roasted grain bill, oats and belgian chocolate. Along with Colorado Ithaca and Bodebrown Milk Stout it is one of the first and few big stouts produced in the country.

It pours a very opaque dark color with a faint reddish brown cap that recedes very quickly leaving no lacing whatsoever.

Aroma is of roasted dark malts, bitter chocolate, coffee/espresso and mollasses. Faint vanilla notes are also there.

Taste begins with a huge roasted punch followed by lots of mollasses and candy sugar sweetness. Notes of dark chocolate, coffee and a little smoked malt are also perceptible. Finish is astringent and fairly bitter from its roasted grain character as well as hops.

Body is huge, thick and syrupy with moderate to high carbonation. Warming alcohol feel after each sip. Aftertaste lingers for a long while with roasted and dark chocolate notes.

Overall a great example of the reinvented Russian Imperial Stout style popularized by US craft breweries. This is a top notch beer, certainly one of if not the best stout currently being produced in Brasil, so be sure to track it down if you are ever down here.

look: 3.75 | smell: 4 | taste: 4 | feel: 4.75 | overall: 4

Black as petroleum with dark chocolate highlights and no head. The viscosity almost produces legs on a PBGC Imperial Glass. More light makes it appear more black, like a reflective black mirror. A thin horizon is reddish brown.

Malt aromas are aggressive up front, very much like wort in the kettle. Some roasted chocolate and coffee is lightly discernible, while alcohol fumes lift pine tar and hop aromas.

The flavor is rich chocolate and black coffee. It is quite sweet with light sourness. Warmth brings out pumpernickel bread and roasted, almost burnt, qualities. The finish is moderately long and dominated by malt.

A dense body with a silky smooth texture. Faint carbonation with alcohol being short of hot. Syrupy residue is left on the lips.

This is a deeply contemplative beer within which one can almost get lost.

It poured the deepest black color possible with no head whatsoever.
Aroma of dark chocolate, caramels, coffee, vanilla, nuts, overripe plums and mint. Not super complex, but pleasant with an assertive nutty cocoa.
Bold flavor predominating cocoa powder following by notes of coffee, mint, mild tangy citrusy, herbal hops, molasses, oat, mild lactic acid, wood, some spices and licorice. Very dry aftertaste with a lingering roasted and chocolate note. Definitely it doesn’t fell like the announced 70 IBUs.
Full body, almost liquorish and very smooth with low carbonation. Alcohol of 12% abv has proven to be dangerously hidden.
A chocolaty RIS, tasty and not aggressive. Sure worth trying. Interesting that the first time I had it, it felt to me like a heavy condimented RIS, this one felt like a much easier to drink brew. And it still has a couple of years to expiration date. It would not bother me to have more spices and hops.

375ml bottle served in a pint glass.

A: Pours a black oiled color forming minimum head. Low retention and no lacings left

S: Roasted malts. Caramel malts. Toffee. Dark chocolate

T: Slightly sweet upfront. Roasted malts. Toffee. Dark chocolate. A little bit sour. I guesd that the high temperature screwed it.

M: Heavy and very creamy body. Low carbonation. Roasted aftertaste

O: Good drinkability. Authentic Imperial Stout made in Brazil

Wäls takes their operation to another level. Not happy with brewing an outstanding quadrupel and tripel, they have borrowed a double stout recipe from DUM and have added Petroleum to their portfolio. This is batch #3 (more on that later), and it comes bottled in a 360 ml size already corked and caged. Many thanks go out to Sergio for this one! On to the beer:

Black as you could imagine, but the story is the color of the head. I have seen heads that are well tanned, but this must be one of the darkest heads that I've come across. It drops away, evenually exposing the beer to the air above. That nose is incredibly delectable. An aphrodisiac even. The aroma is full of melted Mexican chocolate. Soft yeast aromas mix into the chocolate.

As this was the "infamous" Batch #3, I anticipated a beer that would be very powerful with the carbonation. That is the one downside to an otherwise glorious beer. The antithesis to Lost Abbey, a very overcarbonated stout, one that gives the beer a very spicy kick. Time diminshes the intenisty of the bubbles, fortunately. In regards for taste, there are loads upon loads of cocoa and chocolate. But it also has a Belgian accent to it, bringing it Belgian yeast and prunes. It's seems to be 50% imperial stout, and 50% Belgian dark. It's possible that Wäls is using their own house yeast in this homebrew recreation. It's full bodied, and the alcohol is masked very well considering it's already at 12% ABV.

A very good showing from Wäls, and the scary part is this beer can only get better.

More liked than the perfume flavor, besides licorosa appearance. The effect of alcohol comes after, not during. In my mouth the bitterness overpowered the other elements, not being my favorite.

thanks to Jeremiah(froggyfrog)for sharing this at our stout tasting, enjoyed chilled in a glass from the bottle.
The color is very dark almost black like used motor oil with thin light tan head. The smell is roasty with coffee, woody and slightly molasses-like in aroma. The feel is thick as it looks with viscous roasty with medium carbonation and mild alcohol heat.

The taste has strong toffee with cocoa-like roast and taste of coffee is there with a dark cocoa type bitterness and low sweetness with a molasses element with mild alcohol in the finish. Overall I think this is a good imperial stout, cocoa is notieceable but it doesn't overpower the other flavors

From a 375 mL bottle, thanks DoubleJ,

A: Pours black with a tall deep brown head, one of the darkest heads out there, like Chocolate Yeti.

S: Belgian cocoa with a hint of dark fruit, dark chocolate.

T: Dominated by dark chocolate especially on the finish, that flavour is clear. Lighter notes of molasses and roasted malt.

M: Much too carbonated, of this I am sure. Full-bodied, but too much coaxing to get the beer down to drinking level.

O: An interesting Imperial Stout, fix the carbonation problems and you could have a winner because the flavour is there.
