Boulevard Brewing Co.
Missouri, United States

Alcohol by volume (ABV): 10.50%

Availability: Year-round

Notes / Commercial Description:
”Do you know what dwells in a glass?” asks Ole, in Hans Christian Andersen's The Watchman of the Tower. Better known for stories such as The Little Mermaid, Andersen wrote this short, cautionary tale for a somewhat older audience. Our quadrupel ale, also meant for the mature connoisseur, is a deep and mysterious libation, dark auburn and full-bodied, its sweetness deceptive. As Ole describes the glasses in turn, their contents become more ominous until, in the sixth glass...

L -- Pours a deep amber color, with subtle hints of ruby. Thick foamy off-white head with a ton of nucleation points. No lacing.

S -- Tons of Belgian yeast notes are very strong off the bat. Plum, raisin, brown sugar, molasses.

T -- Follows closely on the nose. Takes some warmth for the flavors to fully develop.

F -- Effervescent, medium body.

O -- A level below the best quads, but it certainly sits healthily at that 2, 2A level.

Pour is a deep red/brown with a nice golden head and good lacing. Smells of red wine, raisins, and molasses. Taste is comprised of brown sugar, wine, smokey earth like tones with an alcohol zing. Finish is clean with a light burst of some citrus in there, overall very easy to drink considering its almost 11 ABV. Very nice beer would recommend.

Almost clear dark amber color with beige head. Aroma has brown sugar, molasses and booze soaked dried fruits like raisins and plums. Taste starts sweet with brown sugar flavor, a bit of bitterness too, seems a bit like burnt sugar. There are also dark fruits and yeast notes. Finish is quite bitter and earthy. Medium to light bodied with medium carbonation. Overall it's a well made and complex tasting beer buy I think the flavors don't combine as well as expected.

12 oz bottle poured into a snifter. Moderate head with slight lacing throughout. Flavor intensifies slightly as it warms and this ends up being a solid representation for the style. World Class? Not quite. A tier below.

Enjoyed from a bottle poured into a tulip glass
Look - golden copper, hazy, large head 3" and lots of carbonation
Taste - Prunes, pie cherries, fruitcake, alcohol. A heavy beer you would expect from a Quad.
Feel - Almost bourbon, almost syrup mouthfeel, this beer linger on the tongue long after sipping.
Overall - Good Beer I am still more stout and ipa drinker thus I cannot rate this beer as accurate as some but this beer I would quaff on when looking for a heavy finishing beer. I like the pleasant flavors that linker on the tongue and mouth long after drinking. Dessert in a beer!

Never tried this brewery before, but this was the beer of theirs that the beer store guy suggested so I thought I’d give it a shot. This quad pours a coppery amber color with a substantial foamy yellowish head. The scent is malty with some perceptible fruit tones as well. The taste is strongly malty for a Belgian, even for a quad, which imparts a bready / caramel flavor. There are also flavors of date and fig like the bottle says, I maybe get a little apple too, but I’m not really getting much else. There’s a definite alcohol flavor, which is common to quads, but I tend to find more acceptable if there’s more going on with it than there is here. Not a bad beer by any means, but what I really look for in quads is a complex, dynamic flavor and I’m just not fully getting that here. I usually appreciate strong malts, but in this case I’m not sure it’s totally appropriate to the style and I feel like it may be covering up some of the other flavors. It is rated highly and others say it has a lot of little complexities, but maybe my palette just isn’t refined enough for this one.

look: 3.25 | smell: 4 | taste: 3.75 | feel: 4.25 | overall: 4

Poured from the 750ml bottle to several different kinds of glasses for our tasting.

Look: Pours a ruby-brown verging on tarnished copper. On the hazy end of clarity. Tall, lasting head in the color of beige verging on actual yellow. Scattered, low amounts of lacing.

Aroma: Jeez, where to start with this beast. Right up front it inundates you with rum, raisins, banana, and light clove and caramel... Then it gives you medicinal aromas, almost like treated wood or turpentine. It took a while to nail it down but my tasting group all agreed on this (think railroad ties or fresh cedar). I find some horse-blanket type phenol quality in here as well.

Taste: A lot of the same complexity found in the aroma. The rum and banana are strong. Some dried fruit (dates, fig, raisin). Caramel/toffee flavors. Spicy notes and medicinal notes. Very little or no hop flavors. Quite sweet. And BOOZY, god is it boozy.

Feel: Body is medium. There is a boozy harshness in the mouthfeel not unexpected from a 10+%abv monster.

Overall: I didn't care that much for it, but I'm a hard sell on most Belgian styles in general so I have to give them some leeway. Of the other two people in my tasting (kitchen table), one loved it and the other was moderately impressed. I appreciated the complexity of this quadrupel, but I couldn't get past the medicinal qualities enough to really enjoy it.

look: 4.5 | smell: 4 | taste: 3.5 | feel: 3 | overall: 3

Pours a beautiful burnt orange haziness with a 2 finger tan head.
Smells of rum, alcohol, dates, raisins, clove, banana, caramel, typical quad aromas.
Rather bitter actually, a lot of spice, and alcohol, why...
Mouthfeel is only moderately thick, and not as creamy as expected for this being a quad.
Overall, disappointing, maybe it's because other reviews have been of this after some bottle age, but I find the flavor not sweet at all, very bitter and with a lot of burn, and the mouthfeel was a letdown, it's quite a shame really, I wanted to like this brew.

Really nice solid quad. This is not my fave style so take my notes with a grain of salt. I liked this one and it matches the profile for the style very well. Lots of dark fruits and good mouthfeel.

Best by date: December of 2016 so there's some bottle age here.

The beer pours out into a Duvel glass a hazy dark copper brown color (similar to a used penny) with a 1 1/2" light tan head that recedes slowly leaving scattered patches and legs of lacing on the sides of the glass. Sipping leaves only a few scattered small patches of lacing and cleans the side of the glass. Even midway through the beer there's still a ring of foam and a 1/8" inch layer of foam on the surface and large patches of lacing on the sides of the glass.

The aromas include brown sugar, some dark orchard fruits and just a hint of yeast.

The flavors are much as expected from the nose with the brown sugar sweetness and dark orchard fruits prominent (raisin, date, fig) but also supplemented with some toffee notes, a bit of spicyness (the yeast?), and just a hint of bitterness way in the background. Though out there is absolutely no alcohol burn.

The mouthfeel is medium bodied and smooth with the moderate carbonation. The finish is where the complexity shows most with this beer. The sweetness from the brown sugar and toffee fade to let the fruit flavors emerge briefly. Then as they fade that touch of bitterness pops in briefly then goes away as everything recedes to a nice dryness.

This is a well made American version of a Quad and one which I think can give the Belgian Quads a run for their money. I don't know that it would beat out any of the classic ones in a blind test, but it would certainly give them a run for the money. I'd expect where it might come up short is that the sweetness may be just a bit too prominent here. Anyway, I'll be happy to have this one again and wish I'd been able to include it in the blind Quad tasting some of us conducted a few years ago.

Pours a hazy, turbid golden copper with a foamy, khaki head. Wonderful look and head retention. A bit of lacing is left behind. Dark fruits and yeast form a wonderfully Belgium styled aroma. Dark fruits, malts, and a zing of yeast at the end all work together to form the flavor profile of a beer that could be crafted by Belgium's. Very classic taste. Mouth feel is a tad bit harsh, but otherwise bold, filling, and mouth coating. Overall, a phenomenal brew that delivers classic Belgium style beer from a state-side brewery. Even though this is my hometown brewery, I've never had it, which is disappointing because this is tasty.

Served in a 12oz snifter.

11 oz. bottle, best before date of 08/16 (4 months from now).

Pours a murky reddish-brown with a solid two fingers of frothy tan head. Chocolate covered raisins and figs on the nose, and the taste largely follows. Typical quad notes. Some alcohol heat, but not too much for 10.5% ABV.

Not quite as good as my favorite Belgians but a solid representation of the style. Mouthfeel could be a little softier/creamier. 8.5/10 quad in my opinion.

Wash a gusher when I opened it, dark tan color with medium head / retention. Aroma has Belgian yeast spice, medium british malt (toffee / caramel) and spice. Taste leans heavily on spicey phenols and less so on the malt (which comes through more on the backend with sweet caramel malt). There is some dry hop flavor as well, just faintly bitter but gives it a nice bunch. It tastes more like a Christmas ale or dark strong than a quad, but still a good beer.

12 FLUID OUNCE bottle
Served in a Boulevard Smokestack tulip glass
2013 vintage

This beer pours tea colored and is topped with several inches of tan head that leaves. some lacing.

The aroma is spiced fig and dates. There is also a sweet bread smell with some spiciness from the yeast.

I taste fig and dates with a slight bitterness. It has a very dry finish.

It has a highly effervescent mouthfeel.

This is a very dry quad. It is good, and the alcohol is well hidden.

My first pour after being chilled in the fridge ended up a carbonation disaster but my second bottle was nothing of the sort.

Darkish red/brown color going on with a substantial head. Smells of malt and cherries and tastes of grapes, malt and drinks heavy, yet leaves just the right amount of sweetness on the tongue. Not usually a Quad guy, but this one hits it out of the ballpark. Boulevard has struck home with me many times.

Reminds me of the winey Trappist beers that got me in craft beer.

First had poured from 12-oz. bottle, stamped best by "03/05/17," into Chimay goblet. The creepy literary reference is well-taken, as a bottle of The Sixth Glass may very well lead to another, and so on, and then on to adventures best left unmentioned.

"Man and the devil mixed with blood - that is the sixth glass". A little literature mixed with libation - Boulevard has found a well-chosen literary nod to give with the naming of their latest Belgian. The brewery never fails to impress - though some of their other styles are lackluster, they've got quite a solid bead on the Belgian style.

Had as a 12oz bottle poured into a snifter-shaped wine glass. Pours a deep, hazy gold, with a profuse khaki head. Nose is crisp, but sweet and yeasty - plenty of Belgian spice on the nose. The palate follows in classic Boulevard style - this feels like the big brother of their Tank 7 farmhouse: bready, yeasty, with prolific wheat, but not in the heavy, savory style of a Westy; rather, this beer blends that classic trappist breadiness with a sweeter, more North American take on the quad - there's a certain light sweetness here reminiscent of Unibroue or Ommegang. The mouthfeel is spot on, medium-bodied with the perfect blend of creamy texture and subdued carbonation (less than the head would lead one to believe). Ultimately, this beer straddles the Atlantic, blending the distinct Belgian and North American take on the style, without falling into the trap of overly sweet, overly light quads that so many American breweries seem to churn out. Overall, an outstanding entry in the style.

Hazy amber pour, large old-newspaper-colored head
Smells of cherry, malt, fig, raisin
Tastes of cocoa, clove, cherry, raisin, toasted malt, ester, brown sugar
Heavyish feel, abrasive carbonation
I guess if I was a fisherman or like whoever is the sort of person that calls things a "doozy" I'd use that here. Huge dessert beer. Doesn't hit one note out of tune. Complex almost to the point of exhausting. Seems like the sort of thing you drink to celebrate finishing a 2000 page russian novel

Pour is a cloudy brown amber, small off white head. Aroma has a bit of banana and dark fruit notes upfront, slowly mellows out to some caramel malt, yeast and dark fruit as it warms up. Taste is similar to aroma with some dark fruit and yeast that become more prevalent as it warms up, some herbal hops as well. A full body with good carbonation on the palate. Finish is sweet caramel malt, yeast, dark fruit plums and figs, brown sugar and mild bitter herbal hops for balance with a bit of sweet brown sugar and alcohol on the end. Finish is long and slightly dry. A noteworthy full flavored brew, very nice.
