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...

4.43/5  rDev +6.7%

Many thanks to wagenvolks for the trade! 750mL corked and caged bottle into a Duvel tulip pours a nice murky dark orange with a very nice frothy khaki head that lasts and leaves beautiful lacing on the glass. Aroma is a nice blend of dried fruits and spices with just a hint of alcohol. The taste is a very nice blend of sweet, dried fruits, figs and sweet burnt caramel, quite complex and very tasty! The beer is somewhat heavy bodied, but smooth carbonation does a good job of masking the 10.5% alcohol making this one a very nice sipper. I've enjoyed every beer I've had from this series, and this one is no exception!

A:Pours a nice reddish color with a fingers worth of head that last pretty good, nice
lacing is left down the glass

S:Nose picks up some sour notes that are mixed in with the Belgium funk as well. Very interesting. Also dark fruits,figs, are picked up as well

T:Up front you pick up some fruits and a little tartness followed up by a funk of yeast
that leaves the taste of banana clove lingering around on the palate. Very unique and

M:Mouthfell is good with adequate carbonation, alcohol is pretty well hidden but leaves
the palate a little dry.

D:This seems to be a very well crafted American quad that is easy to drink and has some
interesting flavors in the mix as well. Alcohol is well hidden for the most part, Boulevard
smokestack is no joke and this is no exception.

4.43/5  rDev +6.7%

A. Pours a murky copper with a finger of eggshell white head. Good retention and solid lacing.

S. Brown sugar, dark fruit, vanilla, bread crust. Excellent.

T. Follows the nose with pie crust, dark fruit, especially cherry and dates. Some brown sugar, caramel, and hints of raisin. Truly delicious.

M. Maybe just a little too aggressively carbonated cuts down on the drinkability a touch. Balance, however, is quite good, with a nice evolution of flavors. Creamy finish, mild booze.

O. One of the best quads I have had, and easily in the Top 3 American-produced. A must-try. This would be a staple in my fridge if I lived in KC.

4.41/5  rDev +6.3%

This is my first attempt at a Quad, so I can't really compare it, just note my appreciaition. This one pours a cloudy reddish brown with a tall, large bubbled head. The head stuck around for the majority of the time it took to enjoy this fine brew.

The smell is rich and strong with a slightly sweet scent of dark fruit (dates, prunes, raisons) and a slight herbal undertone.

The taste is also very rich, with the alcohol hidden at first, but getting stronger as the liquid warms. There is a slight bitterness that tempers the malty, sweet nature perfectly.

As noted, the alcohol bites as this warms, otherwise its a pleasant sipper.

Oveall, I am very impressed as I have been with most Boulevard beers that I have encountered.

From the corked, caged 750 ml. bottle marked Batch no. 613081-2-03-2015. Sampled on April 29, 2014 at about 50 degrees.

It is certainly a highly attractive beer to look at with its mahogany amber pour and short-loved off-white head. Good clarity and just a lovely color.

The roasted malts are evident on the nose before anything else. But they are quickly followed up by a cherry-tart fruity character and a surround-sound yeast element. A little boozy but not offensive.

Medium to full syrupy body. Some acidity. It grates the tongue a little.

Like the aroma the roasted malts kick things off with a return play by the cherry-based defensive receiver. There is this definite pungent tart bite that makes me wince briefly but I get used to it. Some dry afterbite for certain. A little booze but that's to be expected at 10.5%. I wonder how it would be at this time next year with proper cellaring

S - deffinitely picking up alcohol plums candy smells a nutmeg spice aswell

T - plums a sweet honeysuckle alcohol taste.

M - medium body with creamy bubbly finish

O - very very complex every nose is different and taste dark fruits exploding on the palate.

Pours deep ruby with tremendous off white head, more like Boulevard's stellar saison - an exceptional beer in it's own right.

Taste is rich, raisins, molasses figs and just the right amount of sweetness with alcohol finish. Really great quad. Smokestack series doesn't disappoint.

Will definitely buy again.

Dark murky brown with plenty of reddish tones, great carbonation at the bottom of the glass. The head is light tan, bubbly and thick but not creamy. Very light lacing.
Phenolic aromas are strong, spices and dark fruits are well represented in the aroma but not overpowering. Mild apple and oranges zest also come through.
The hits thing you taste is the slight smoked dark fruits-yep you read that right smoked dark fruits, followed by the overall sweetness and then a mild bitterness as you swallow. I do taste some apricot and mild peaches around the center of my mouth. Prunes and a mild brown sugar flavor come out as it warms up.
This is a medium to full bodied ale and it really coats your mouth with a wonderful feeling and flavor.
This is what I would expect from a quad and this quad is one of the many great quads out there. You must try this one.

4.4/5  rDev +6%

A: pours a brownish red, it's cloudy without yeast particles. Foam is one finger high, beige and leaves no lacings on the glass.

S: raisins, figs, dates, loads of banana, alcohol and belgian yeast.

T: banana, honey, malt sweetness, dark fruits, rum and condensed milk. The aftertaste is metallic and the alcohol is there, for sure, but it isn't aggressive.

M: it's very light, small bubbles, carbonation is medium high.

O: it's a great beer. Could have been more taste, but it's complex, the flavors are all there, as is the belgian feel. I enjoyed it very much, but it didn't quite live up to my expectations. Will have again for sure though.

Drank from a goblet.

4.4/5  rDev +6%

A: Pours a thick hazy amber color with a good off-white head that keeps its form. Good carbonation. Great lacing.

S: Malt, hops, biscuit, banana, citrus, floral, slight caramel, slight vanilla.

T: Malt, hops fading to the back, banana, slight biscuit, citrus notes, caramel notes, faint coffee.

M: Good dryness. Very smooth with a great balance of flavors. Deep and mellow.

O: Very tasty and smooth quadrupel with deep, balanced flavors. Almost like a heavier version of a Duvel. Nice dryness that's not overwhelming. Bottle indicates aromas of date and fig, which I didn't pick up (and I'm not sure I'd recognize them anyway). Quite drinkable even with the high ABV.

Amazingly delicious easy sipping dark fruit concoction

This is a nice after dinner brew in a snifter or tulip.

Cloudy pour with a soft foamy head on top

Sweet and rich, some noticeable alcohol but not overly so. Caramel, toasty rum-raisin bread with brown sugar and , cinnamon, plums, figs

Smooth in the mouth and disappears in the glass too quickly...

Another winner from Kansas City. How can you not like a quad that is packed with fruit, isn't overly fizzy or belchy, doesn't overpower with yeasty booze, has a subtle taste of almonds AND goes down well with an obscene fistful of Nestle chocolate chips? The alcohol is well hidden and doesn't make it impossible to sight-read Schubert song transcriptions at the piano. Well worth the cost.

Deep glowing fog of burgandy with a ruby tint to its body when up to a strong light. Emensely thick and tall head of yellowy tanned foam bursts to top it and sits well for a while before fading to an always present amount. Big droppily patched and broken sheets of lace stick across the goblet.

Big and booming aroma of berries and dark sweet fruits flow out of the bottle right during the pour. Very pleasing to the nostrils...Once settled in the glass this has a very nice nose of dark berry and rum soaked fruit bread. Date, fig, raisin, candied sugars that are all very rounded and sugary sweet. Quite nice!

Taste nearly mirrors what the smell delivers with an even better display within its reflection as a whole load of dark, sweet, chewy, sugary, robustly full flavor takes place with a nice perk and ease of girthy smooth breadyness and carbonated chewyness. Only slightly heated after the swallow this has alot to offer in a well toned and flavorful array of dark sugary fruity stuff that sticks and chews with dates and figs, flirts with raisin, dark orange, berries, and cherry. Dances with sugary spices that tantalize and dance away a fine lasting deep seeded taste across the finish.

Full bodied and chewy with a smoothly dark setting of rich carbonation. Finishes with a bit of fever and warmth and a whole bunch of pitch within its taste and balance.

Wow, a surprisingly solid and well mannered Quad that looked, smelled, felt, and tasted like something right out of the Belgian realm from which it is to emulate. Great job by Boulevard on this one!

Chilled 750 ml C&C bottle poured into a Troegs stemmed tulip. Bottling date is misprinted and rather hard to read, but it appears to indicate July 7, 2011.

Look- Cloudy medium amber with a bit of sediment, despite my best efforts. Big (four+ fingers), craggy, sticky, foamy buttermilk-colored head. Actually, it looks quite a bit like whipped pancake batter. Clings to the sides, leaving a craggy bowl-like meniscus. No lacing once it finally settles, which is expected at this ABV.

Smell- Big fruits- strawberry, grape, apple cider, ripe banana, and bubblegum. Reminds me of gewürztraminer wine, in fact. Spicy/flowery yeast, some booze and strong toffee/caramel malt round it out. Alcohol/flowery character builds as the beer warms and the head falls, making it more boozy and perfume-like, but never too much so. Exceptional!

Taste- Bold flavor, mellow feel. Starts out with strong candied pears, treacle, and summer melon. Toffee, graham cracker, rye whiskey, and sassafras push through before transitioning to lemon zest, fresh crusty bread, and a bit of peppery alcohol. Aftertaste is akin to decent peach schnapps with the faintest hint of bitterness. There are more than a few subtle flavors here that I can't really pin down, but it's delicious and beautifully put together.

Mouthfeel- Full body, mild to moderate carb. Creamy feeling, silky smooth,. Mildly astringent towards the finish, alcohol is definitely present throughout but not offensive. Significant warming, surprisingly clean finish. Drinks like a dessert wine or liqueur.

Overall- Extraordinarily well balanced- not "too" anything, and goes down deceptively easily. There are plenty of big beers around, but it is rare to see one that showcases so many elements so well without seeming chaotic, and man, is it good! I'm planning on going out tomorrow to grab a bottle (or six) for uncorking down the road.

outstanding beer, as all the smokestack series have been. i got a 120z. bottle of this for less than 3 bucks, what a deal! pours into a thick stemmed chalice a deep mahogany color with brown and red forces combining in stunning beauty. a thick tan head comprised of very large bubbles rests casually on top. smells very rich, caramel, toffee, belgian yeast, brown sugar, and raisins are all involved in a very complex aromatic experience. flavor is amazing too, for awhile i was thinking fruits like figs or dates as the label suggests. it really does have that dried sweet middle eastern fruits kind of flavor going on, but it also tastes very similar to those bit-o-honey candies you still see around sometimes. very very intriguing and delicious. intoxicating as hell at 10.5% and so yummy, be careful, this is a sipper despite its down easy feel. carbonation is medium but takes on a very laid back characteristic. medium body is perfect. its sweet in the finish, and warm from the alcohol, but not unpleasant in either sense. this is one of the best american quads i've ever had. really.

Poured at room temp (sorry) in Harpoon tasting glass.

A: clear, dark red-orange; strong head but large bubbles that disappear quickly; modest carb
S: yeast leaps off the cap; malty
T: very full, complex quad with all the gravity and yeast one expects in the genre; malt is slightly on the roasted side (a nice touch I think); long lingering flavor of hops, yeast, and booze

wonderfully warming; would make an excellent winter beer

750 ml bottle (Batch #68100) poured into a Three Philosopher's chalice.

My fourth of four in the so-far solid Smokestack Series, The Sixth Glass pours a beautiful russet copper & ruby red hue, with a towering two-inches of effervescent, khaki foam. The head retains well, thanks to an active carbonation level that sends streams of bubbles careening toward the veil up top. A rich caramel nuttiness and lots of apple fruit esters dominate the aroma, while hints of black licorice and ethanol dance in the background.

Wow...this is an impressive Quad. Complex, inviting caramel and Belgian malt layers balance perfectly with floral, semi-bitter hops and subtle, fruity yeast notes. I'm immediately taken aback by how well-hidden the 10.2% ABV seems to be; the only hint of booze is a warming finish. Mouthfeel is creamy, softly carbonated, medium-thick, and finishes beautifully. All in all, this is an excellent Quadrupel that lives up to the Smokestack name. Not only that, but I'd guarantee that this beer ages well. I'll be picking up some more for just that purpose soon.

750 ml bottle, corked and caged. Batch number: 68044.

A loud pop and a hissing pour reveal a hazy, glowing amber with ruby edges. Big, rocky, towering, light khaki head that sticks to the sides of the glass nicely. Nose shows off sweet candy sugar, dark tropical fruits, raisins, a hint of bubble gum, and some yeasty sweet bread.

Toasted malts and singed banana bread up front. Sweet tropical fruits and bananas follow. Layers of plums, pears, and raisins come in, with hints of toffee, and coconut rum. Yeasty, with lingering ripe banana and toffee in the finish. Warming. Full-bodied, with a thick, smooth feel. Delicious and very well done!

Purchased at the BSF-GBBF 09 and coming in a 750ml green bottle, corked and caged, this bottle bears Batch No. 58312 instead of freshness info.; served faintly chilled in Gulden Draak's tulip-shaped bowl sniffer.

A: pours a brilliantly clear, dark reddish-brown colour even with purple-ish glows, coming with a 1.5cm-thick dark beige frothy head supported by healthy streams of microscopic bubbles in action - looking just gorgeous...
S: the nose is nice and complex, reminiscent of a Belgian Quadruple but minus candy sugar, but a bit like a cross b/w Old Ale and US hop-focused barley wine as well; featuring lots of tea-smoked prunes, raisins, overripe apples+pineapples, brown sugar, burned sugar cane, brown malts, aromatic grapes, sweet herbs, and sour-sweet notes of well-aged sherry.
T: a creamy swallow of dark fruits plus brown malts is seamlessly ensued by a caressing blanket of aromatic black sugar, high quality black prunes, roast nuts, and bitter toffee, while the hop influence soon catches up like an undercurrent full of bitter-sweet root herbs, leading towards a "dry"-ish finishing palate more like a mature Oloroso Sherry actually... The slightly chewy and herbal side of hoppiness as well as the lingering aromatic malts also stay deep down the tongue, rendering a truly inviting effect more in the fashion of complex but well-hopped old ale than an estery Quadruple.
M&D: the mouthfeel remains as creamy-smooth and healthily-carbonated as any quality bottled-conditioned beer must dream to achieve... The body never goes too heavy - in fact extremely balanced and approachable against its alc. strength. Also, the hoppiness balanced with the fruity-maltiness in the aftertaste prolongs the depth and complexity altogether. All in all, this Quadruple-style ale is slightly too expensive, but I've made my efforts to fully enjoy and memorise every single drop from this bottle~~ This is perhaps the best bottled beer I've tried for many months now, even outperforming Westvleteren 12 as far as my last bottle last month is concerned.

Boulevard has been moving up my ranks as an incredible brewer for a while. Their 2013 sampler with the RyePA and Mid-Coast IPA, along with their 80-acre, is astounding.

This "The Sixth Glass" Quadrupel was a part of a create your own "4-pack" - Extremely happy with my choice

A- Beautiful hazelnut orange color with a tall, tan head

S- Bread, citrus, and nuts

T- Caramel/Toffee flavor with a citrusy (apricot) flavoring. Nice toasty quadrupel - the ethanol is present

MF- Velvety, carbonated goodness

I would refer this to everyone of my KC and non-KC friends alike. Great ale. Thank you, Boulevard.

4.38/5  rDev +5.5%

A bit light for a quad, but it's still an attractive beer. Kind of a ruby/amber mix in terms of color. The head is thick and offwhite, has good retention as the inner part of the head starts to fall first leaving a thick perimeter of lace around the edges.

It actually smells sweet. Dark ripe fruits and candy, grapes and raisin fill the nose.

Really, really good taste...I'm considering a 5 for it. Everything from the nose eventually hits the tongue providing a fruity, yet very beer-like taste. Carbonation, a tinge of hops and a slight taste of alcohol in the finish.

Layers of complexity. It's full-bodied and sweet, but not too much so...just the right amount for this beer. Some spices provide another layer, followed by a little bit of bitter. The finish is both sweet and dry, with lots of carbonation, and a tingle of warmth from the alcohol.

An exceptional beer. I'd have guessed this to be a true Belgian had I not know where it was brewed. Absolutely nothing wrong with this beer, nothing to even nitpick about.

Huge thanks to csmiley for splitting the 750.

Batch #67283

Appearance: It's very hazy and a darker caramel brown color. Due to some light getting through, there are a some scarlet highlights. Carbonation is very active and yields a large two and a half finger head that's a nice looking tan color. There's a few light chunks of sediment floating around. Due to continuous carbonation buzz, it stuck around a long time. A sticky coat of lace clung to the glass.

Smell: The nose initially smells like brown sugar and is very sweet. It is a little spicy and features some pepper and other spice aromas. I can't quite identify the others. There's a distinct tobacco smell to it and perhaps even a little leather. Some light dark fruit aromas are present (raisin and plum). Alcohol is lightly noticeable on the nose, but it's not overpowering. Very impressive for a 10.5% abv beer. The ever impressive Belgian yeast aroma emerges toward the end, adding a stamp of authenticity.

Taste: It is moderately spicy up front. Pepper and some other spice flavors are noted. There's a nice berry fruit flavor that adds some character. Some earthy flavors follow it up. It's mostly tobacco, but there is something that resembles leather. Dark fruit flavors are present and are much more prevalent here. It is raisin and plum. They take an active role and add quite a bit of flavor. Very impressive. Alcohol is noted on the tail. But, it's well balanced for a 10.5% beer. You wouldn't really guess that it's that high. It finishes sweet and a little spicy.

Mouthfeel/Drinkability: The mouthfeel is pretty thick and it's very creamy. This is one is very lush and appeasing. Carbonation is very active, but it in no way detracts from the ultra-smooth feel. Drinkability is astonishingly high for such a strong beer. At 10.5%, it's too strong for a lot of drinking. But, it's very easy drinking. I'm really enjoying this beer. I'd have no trouble tackling a 750 by me onesie.

This is my first experience with Boulevard and it's been very impressive. The Sixth Glass can easily compete with some of the top Quads out there. Given that it's brewed here in America only makes it that much more impressive. I can't really identify any material flaws here. This is a very good beer that's worth seeking out.

Deep crimson orange, frothy creamy foam, visible micro bubbles. Soft fruity notes, nutty, with an earthy, bready, cookie sweetness. Dried fig, apricot, dried cherries, rich and cakey with some delicate almond in the background. Full bodied feel, mellow, dries out quicky, leaving a rich aftertaste. Slow sipper, but not heavy, cloying, or alcoholic at all.

Shared this one with family for the holidays...

A curl of smoke exited the bottle once the cork popped. The body was a rusty orange-brown, with transparent clarity. Good amount of foam, it's color had a rust tinge to it as well.

Nutty aroma of almond, maybe dates also. Subdued and not overly sweet like some Belgian Quads. Malty flavors with strong estery notes from the yeast. More dried fruits and nuts, with a slowly dissipating warmth following the finish. It was sturdy, but not heavy or syrupy. Light enough to want to finish the whole bottle easily. Great choice for a winter night, with good cellar potential.

A: This is a very nice cloudy ruby red color with a thin white head that quickly fades.

S: This has your typical quad smell and a strong amount of sweetness. There is a lot of fruit on the nose too and even a tiny bit of alcohol.

T: There is a nice bit of malt and fruitiness. I am bad about describing the quad taste, but it has a great quad flavor. I just love the taste and it is by far the best part of this beer.

M: There is a tiny bit of carbonation and hardly any crispness on the back of the throat. The beer drinks like water and close to the easiest drinking quads on the market.

O: I am a sucker for quads and this beer hits the spot. It has so many flavors that just explode on the palate and all the other aspects of the beer come together to make this great. I am glad I can get this anytime because it never gets old.

104th review on BA
Bottle to Tulip

12 oz bottle.

Again, thanks JeepCop for the extra.

App- Such a weird brown color with a mix of browns ranging from dark, mahogany to some lighter brown hightlights. It was capped by a 1 finger head that was very bubbly. Suprisingly, this quad was quite lively in the glass.

Smell- This was a bit boozy in a subtle way with a bit of figs and dark fruits. A rich malty essence.

Taste- Its a big drinking 12oz bottle. Not as much booziness on the taste as the nose which I thought was pretty damn good. Im suprised by how good this is. I think its personally better than BBQ.

Mouth- A big full bodied beer with a medium carbonation to it. Has a very superb spicy after taste.

Drink- I could do another one even at the 10.5% These 12oz bottles could do some damage in a 4 pack.
