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...

Belgian style quad from Kansis City? Sign me up.

Pours a rust color w/ a small white bubbly head. Produces nice soapy lace on glass.

Yeasty aromas. Bubble gum. Small caramel & toffee notes as well. Raisin.

Big yeast flavor with some spiciness balanced by the sweet fruit & caramel presence.

Feels a bit warm & carbonated for my tastes. Alcohol is very present. Not a bad thing.

Kudos to Boulevard for brewing this. Glad to have tried & would gladly have again.

Perfect appearence. Deep ruby color with a full, long lasting head of a light tan. Fairly nice nose, with a lot of Belgian character. Plentiful dark fruits (cherries, dates, plums,) and a touch of alcohol. Flavor is loaded with tons of depth. Deep caramel and honey glaze, with dark fruits. It's a really nice beer and very Belgian. I think this series from Boulevard shows their brewing skill.

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

Into a duvel glass, this beer pours out a dark cloudy brown with a huge frothy head. Aroma is a bit faint, spicy & sweet. Very sweet tasting, almost too sweet for me. It has got a load of dark fruits and lots of appropriate and interesting phenols, but I find it close to cloying. Peppery alcohol apparent in the finish.

The first of the Boulevard Belgians that I haven't cared for.

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

Full yellow-tan head over a cloudy dark red-brown liquid. Smells toffee, brown malt, chocolate. Earthy, dark fruit is mild. Clean ethanol sting.

Tastes peppery, chocolate, clean alcohol sting, mild toffee. Cherry and streched thin raisiny. Mild belgiany phenolic character persists as an undertone. Strong carbonation with noticable alcohol to wipe most of the sweet of the palate. Leaves a dry residual chocolate in the aftertaste. Good drinkability now, I'll bet this one ages to become fantastic.

Thanks to hwwty for this one.

A: Pours a nice brownish orange hue with a nice bubbly head. the head dies to a nice lilly pad and some spotty lace is noted.

S: Big bold dark fruit aromas. Tons of raisins and figs. Touches of cinnamon and nutmeg really come thru along with some alcohol burn.

T: Taste matches aromas. The raisins really stand out. There is a nice blend of spice and a hint of bitter zest. The alcohol is very noticeable as is a touch of oak. Did this one spend any time on the barrel?

M: Medium in body, The carbonation was noted in appearence but not so much in mouthfeel.

D: I drank the entire bottle but is was not easy. As a pint I love this one, but 750ml it becomes a bit sweet and boozy. That being said it is a very good brew, from a brewer that is new to me.

Pours a dark amber brown with a huge tan head. Smells of alcohol and oak and a strong presence of sour cherries. Tastes of cinnamon, brown sugar, and a slight amount of earthyness. Not as dry as other Quad's but quite good. Mouthfeel is rich, with massive carbonation. Drinkability is quite good, especially for over 10 percent alcohol. An excellent American Quadrupel.

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

750 ml bottle with the obligatory devil caricature on the front label. The back label includes a batch number and glass recommendation.

Poured into and oversize wine glass. The head was quite thick, but it dissipates quickly. The residual foam sticks on the sides.
The smell is intense, nuts, oats, honey, and orange zest. The taste has hints of caramel and wild honey. The alcohol presence does its best to cut through the sweetness but not enough to balance the flavor.

The mouthfeel is thick and creamy and a finer point on this beer. It reminds me of Stewarts country orange and cream soda.

The drink ability is surprisingly good given the alcohol content, but the strong sweet flavors kept me from having more than two glasses at one setting.

I find quad's to be a widely varying style but one I am drawn back to quite often. So, that said how's the boulevard offering? I found it "quad subdued". What the heck does that mean? It's got sweet caramel candied fruit malt aspects, a solid belgian yeast aspect, the right color and a sticky lacing head. It's also boozy and the flavors while blended well are more subdued than I would prefer in my quad. Worth a try.

This is the last of the Smokestack Series for me, and I can't imagine I would be any less impressed with this one than the previous three, but I better make sure. Pours a dark copper with some almost indiscernible streaks of red into a snifter. Has a huge foamy tan head that recedes in a dilatory fashion leaving little lacing behind. Has a robust and complex smell of raisins, figs and other dark fruits with some alcohol right behind mixed in with some big malts, caramel and toffee. Tastes is just as complex as the smell with some big malty creaminess, light chocolates, caramel, sweet bread, some grains, dark fruits, hops and some big alcohol heat bringing up the rear. Mouth-feel is medium bodied and smooth, but the big alcohol heat might be a turn off for some, although is welcomed to me. There is plenty of brisk carbonation to keep things exciting. All I can say is hell yeah!

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

Dark burgady ruby red blend. Big airy beige head is erected with the pour. It fizzles out fairly quickly, but a nice little frothy head has some staying power at the end. Decent nose, but overall, too sweet smelling. Blackberry Brandy comes to mind as does cherry juice and sweet rock candy. I think this is appropriate to an extent, but my nose tells me it's a little overdone. Let's proceed. First impressions on the palate are spicy, sweet, yeasty and alcoholic. This is not a bad take here on an extraordinary style. Brandy soaked figs with some plum and raisin. A little of that "spiked punch" feel to it. The alcohol is all over this, but never really off putting. Rum soaked fruits make their presence, like apple and melon. Light-medium bodied with a moderate level of carbonation. My only recommendation here is maybe a little less heat and a little less sweet. Overall though, this is a good beer.

I had this one sitting in my fridge for about 6 months.

A - Poured out rich burgandy color. It was semi-opaque with a small, long lasting, tan head that left behind soapy trails of lace.

S - It smelled of dried fruit, like raisin or plums. There were spicy aroma and notes of malt, too.

T - Dried fruit and spice dominated the first few sips. The smooth malt and caramel tastes emerged more as it warmed up.

M - It was soft and had a warm alcohol presence. A medium to heavy-bodied beer.

D - This is a very good Quad. I was really impressed with Boulevard's take on a big Belgian style.

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

Pours a murky brown color with some reddish hues. Big cream colored head with great retention and lots of lacing left behind. Aroma is alcohol, dark fruits, and spice. Taste is a bit boozy. Some funky yeast. Pretty spicy. A bit fruity with some pears and raisins. Mouthfeel is very thin in my opinion for a quad and it doesnt lend to the drinkability because of the high and noticeable alcohol. Not bad but certainly doesnt stack up to the trappists i've had.

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

Apperance: Pours a clearish, mahogany-hued body sporting a ring of tiny, white bubbles.

Smell: Malty aroma crammed with dark caramel overlayed with alcohol-soaked plums and cherries and wrapped in a light, delicate yeastiness.

Taste: Full maltiness and a strong Juicy Fruit bubblegum taste and a little pinch of acidity. Some spiced bananas, a pinch of crushed rock candy. Slight yeast character. Hint of toast. Warming finish with a lasting taste of fruit-flavored bubblegum.

Mouthfeel: Medium-bodied. Moderate carbonation.

Drinkability: A decent quad and pleasure to have tried it, but one is enough for me, thanks.

Pours dark red and orange with a strong 1/4 inch head. Average lacing. Nicely carbonated with a super sweet Belgium hoppy flowery citrus smell. The light hops balance well with the malts and Belgium yeast. It finishes with a lovely sweetness with just a hint bitterness. This is not a disappointment. Recommended!

750ml bottle: Batch 68018: This one opened with a loud "pop". It poured with a large tan head on it, and was quite fizzy. The color was a hazy mahogany. The head dropped off rather quickly. The nose is good, but not as strong as I would have expected. Mainly bready and spicy, with traces of caramel and fruits. A bit of effervescence on the tongue. Not quite full bodied. It took a couple of sips to appreciate the taste. Subtle hints of different tastes, but they all blend well together. Nice.

Pours a deep ruby red/brown color. Smells of rich malty sweetness(apricots, prunes) some yeast and bread, subtle hop kick. Coarse head is intimidating but settles to a decent layer quickly and fed by very good carbonation. Tastes is somewhat complex. Lots of carbonation in there and in the finish. Tingles the tongue in the beginning. Transitions to a subdued malty sweetness. Finishes strong with a meddly of hops, carbonation, and alcohol that seems to go on forever. Nice body to it but seems to soften as it opens/warms up.

Recommended by the helpful friends at the Neil St. Piccadilly in Champaign, I grabbed this from the Boulevard display, eager to try something from their Smokestack series. This did not disappoint. Rich, cloudy burgundy body, topped by two fat fingers of off-white foam, with plenty of lacing on the Yankees pint glass--used because I was watching the Yankees-Red Sox game; splendid presentation. Nicely aromatic, not overwhelming but thankfully complex--cherry, berry, chocolate, and hazelnut coffee.

This is really delicious. The cherry stood out to me, but various flavors emerge in turn--coffee, caramel, back to cherry--not too sweet but certainly not tart. Very impressive in its balance. A winner. The mouthfeel seals the deal for me--well-carbonated, smooth, and durable--never flattening out, fresh though lingering with me for a couple innings. Well done. The alcohol does start to weight heavily near the end, reducing the drinkability a bit.

This quadrupel is not overwhelming in its flavor. For people looking for a big, brash quadrupel, this might disappoint. Yet for those looking for a good, well-crafted, well-flavored, smooth Quad, this should satisfy. At $8 for the 22 oz. bottle it's a little pricey, but certainly enjoyable enough--and a bit boozy enough--to ultimately overlook (or plainly forget) the price in favor of the flavor. Definitely recommended.

A: A bit light for a quad in my opinion. It has a nice deep red body with a nice off white head.

S: Spicy with a good malt profile. There are some dark fruits in there also.

T: Spicy like the flavor. I get a bit of clove along with more dark fruits. A bit too spicy for me overall. There is a good caramel flavor.

M: Nice creamy body.

D: Not too bad, along the lines of La Trappe Quad if I remember correctly.

Thanks to my uncle for sending this to me.

So far, this is the best of the Smokestack series.

Poured from the bottle into a pint glass. Looks like a typical quad with a murky brown color, only slightly lighter with more of an amber tint.

Nose is a somewhat mellow, floral smell. I got some bananas with a little bit of prunes.

Taste is outstanding. A very warming brew but the alcohol is masked very well. Definitely packs a punch.

And outstanding quad. Glad I got the opportunity to try it.

Wow what a beer.

When I heard Boulevard was brewing a Quad, I honestly didn't know what to think. I felt it would be good... but never in my wildest imagination did I expect it to be 'this' good.

This stuff rules!

The beer pours to a light brown with a nice above average head. The lacing never lets up.

The smell brings to mind dried fruits, vanilla oak and cola.

The taste is pretty close to heaven. Surprisingly comparable to The St. Bernardus 12's and Rochefort 10's of the world. Boulevard should be proud of this one.

If Boulevard is going to move in this direction, then The Smokestack series is a great start. The regular line of Boulevard brews is nothing to be ashamed of, but these SmokeStack beers seem to be pretty special

A Boulevard Quad? So nice. Much thanks to BuckeyeNation for providing the bottle.

Off comes the wire cage, pop out the cork, and it goes into a Westmalle glass, seems fitting.

Impenetrable appearance, a hazy burgundy hue, with a slight, yet attractive creamy head.

Enticing aroma....bewitching, sweetness and spice. Dark fruits and funky yeast. Lovely stuff!

Taste: sharp, phenolic, alcoholic, but still beautiful. Cherries, and sherry, a bit of port, but moreover musty yeast at play. Wish it were smoother, and not so brash on the tongue, little quibbel, there, but it is tasty, and reminds of my favorite Belgian quads, for sure.

And they came up with a very unique way to reference the Devil, from, of all places, a Hans Christian Andersen story, that goes on about indulging in alcohol. What's in the "Sixth Glass"? Why, let me tell you...
"In the sixth glass sits the devil himself, he is a little, well-dressed man, most charming and pleasant. He understands everything you say, he even brings a lamp to light the way, not to your home, but his." It goes on and becomes more moralistic, gory, and damning. Sorry, Hans, I've got more living to do, before I get melted, and that includes drinking six glasses sometimes!

Yummy. Alcohol is too prevalent, ...10.5%!...I'd rather feel more flavor, but this is a nice acheivement as it is.
Several stretches short of greatness, but an enjoyable glass or two, or six...

Batch 67299 poured chestnut with 1 finger of off white head. Above average head retention & good lacing

S: Chewy malt, a bit of chocolate, oaky with & some bourbon notes as this warmed up

T: Caramel & breadyness & booze up front. Bits of oaky dryness & boozey warmth come through as this warms. Finishes syrupy sweet with fruity notes

MF: Chewy, but a touch carbonated for my liking

Drank pretty good, probably needs to age a couple of years to smooth out some of the boozeyness. Went well with my Christmas dinner (goose)

Pours a dark red, good color, with a light fizzy head that quickly dissipates.

Smell is sweet - lots of raisins, dates in there.

Tastes sweet, but alcohol is slightly offsetting and warming.

For a 10.5% ABV, extremely drinkable.

As others have stated, I'm very happy to see Boulevard going in this direction. I've suggested the Smokestack series to many of my local friends who haven't tried a whole lot of exotic beers, and the Sixth Glass seems to be one of the favorites among them. Highly recommended.

750 ml brown bottle.
"batch number: 67283"
No. 1 in the Boulevard Smokestack Series.
"...a deep and mysterious libation, dark auburn and full-bodied, its sweetness deceptive."

a: A hazy reddish brown with light tan colored head that is reduced to a thin layer of bubbles within minutes.

s: Caramel malt and a cola-like sweetness, maybe some dark fruit too.

t: Sweetness similar to caramel, cola, and raisins. Some yeast flavors with a nice spicy alcoholic finish.

m: Very syrupy feel on the tongue. Full body, nice carbonation, dry finish.

d: You can certainly feel the alcohol, but in my experience, that's common for quadrupels. It isn't too sweet, has an enjoyable flavor and a great warming effect. The Sixth Glass seems to stack up pretty well to the other Quadrupels I've had, though my experience is admittedly limited. Frankly, I'm impressed by Boulevards choice here, not many US breweries make a Quad, seems like a ballsy move on their part.
Overall, its an enjoyable beer that has me excited to see what Boulevard does with this new series.
