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...

4.45/5  rDev +7.2%
look: 4 | smell: 4.5 | taste: 4.5 | feel: 4.25 | overall: 4.5

Poured from a 12 oz. bottle into a St. Bernardus goblet glass. Best by date of 11/09/14.

Appearance: Pours a deep brownish mahogany amber orange with a moderate amount of bubbles. About two fingers of off white head which slowly fade into a thin patchy layer. Leaves a decent amount of lacing.

Smell: A big, rich, and sweet aroma of spicy yeast, dark fruits, and toasty caramel malts. Belgian yeast with hints of funk, clove, cinnamon, and peppers. Big fruit esters with hints of bananas, pear, apple, and grape. Big dark fruit esters of raisin, fig, dates, plum, prune, and dark cherry. Sweet Belgian candied sugars and brown sugar. Big toasty sweet malt presence with hints of caramel, toffee, biscuit, and grain. Some alcohol hints come through as well. A very good Quad aroma.

Taste: Follows the nose with a big taste of yeast, spices, fruits, and caramel malt. Spicy Belgian yeast with notes of clove, funk, pepper, and cinnamon. Big mix of fruit taste with notes of bananas, apple, pear, and grape with dark fruit esters of raisins, fig, plum, dates, prune, and dark cherry. Sweet mix of Belgian candied sugars and brown sugar. Deep toasted malt taste with notes of sweet caramel, toffee, toast, biscuit, and grains. Light background presence of earthy hops. A really rich and good all around Quad taste with a little alcoholic kick.

Mouthfeel: Thick and full bodied with a moderate amount of carbonation. Creamy, juicy, and somewhat slick. Moderate alcohol presence.

Overall: A very good American version of a Belgian Quad. Great yeast and fruit esters with a good sweet malt base.

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.

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!

Absolutely one of the best Quad's I've ever drank! Nice deep yellow color with an orange hue. The aroma was like heaven, with all though components (spices, fruit, hop's and malts) and you can't believe your drink an ale that's 10% alcohol. So mellow, but be careful, it can jump up and bite you! Great brew, can't wait to buy a case of four packs!

Poured into a Chimay goblet from a 750ml bottle.

A - Pours a nice dark amber color with a light tan color head that is extremely active and about 1.25 inches.

S - Smell is very fluffy and gentle but at the same time very delicious and present. Nice sourdough and bready smells with some caramel notes very present. Mild clove and some spice as well. Great malt profile.

T - This is where this beer sores in my eyes. Delicious and smooth malt sweetness with some mild phenolic tastes. Spices a plenty with some vanilla and cinnamon. The malt profile is so full, complex and delicious very good offering. Delicious beer. One of the best if not the best of the Series. Some nice alcoholic notes along with dark fruits as well.

M - Creamy and nice CO2 content and feel. Fluffy with a nice full body.

D - Very drinkable especially with the high ABV.

I think my first quadruple ale, at least that I can remember.

A: Lovely dark copper, cloudy, caramel, poured into my Duvel tulip didn't leave much of a head. Hardly any lacing.

S: Some apple and cinamon, fermentation, smoky, very inviting.

T: Hits very nicely, just want to keep drinking, sweet malt sugar and spice with a clean finish.

M: Simply put it just feels good, definately wanting more. Hits the tongue fast and washes over with a slight bitter almost brandy wine taste to it.

D: Very drinkable, At over 10% abv it definately sneaks up on you. Wanted another right away, probably lucky it only came in a 4 pack!!

Opened this up which was corked, I hate opening corked bottles, this one foamed out all over me. Oh well

Pourd these into my goblet, it made a nice 2 inch head that went away pretty quickly. Did not notice any lacing at all.

It smelled citrusy, very fruity, like berries and banana bread, a hint of yeast.

First thing to hit my mouth was a nice sweet fruity taste, then a hint of nice spices.

Mouthfeel felt a little bitter with a noticable tatse of alcohol and carbonation

Drinkability was pretty high for this one. Would have it again.

Picked up a bottle at Princeton Liquors in Maple Grove. Man, this is my favorite quad that I've had in a while, and I had a Pannepot the same day. At first it smelled of spiced rum, but as it warmed sweet dates and black cherries came out with a tinge of cinnamon and ginger. Clove phenols grow, but never overpower as the beer approaches room temperature. Very drinkable and rich in flavor. Something a bit different from your normal caramel-malt driven quad. I'd call this must-try for quad-lovers.

Pours a hazy walnut color in my Orval glass with a thumb sized tan head. head falls fairly fast with no lace to speak of.

Aroma is nice big malty caramel, fruit cake lots of plums, raisins and fresh apples. Some light spice and yeast notes underneath the wonderful sweetness.

Taste is like nose big huge malt notes, lots of caramel apples molasses seeming to mingle through out. Finish is where dark fruits appear plums, sugar coated raisins, even some pear notes to mingle with the spice and add a touch of dry tartness. Man this baby is good so sweet and chewy but not cloying at all. Finish is lightly peppy spice with a touch of hops. Alcohol in not noticed other then a touch of warming in the finish. Very well done Boulevard.

Mouthfeel is good just enough carbonation to give it the needed kick with out being to much, which is an issue i have with some Belgian styles. Body is nice medium.

Drinkability is great, not my favorite style prefer a good Dubblel but this one is very well done and I am wishing I could get more locally. Nuff said if you see it buy it you will not be disappointed.

750 ml Bottle poured into my lost abbey stemware glass

Pours a deep amber-highlighted mahogany color with an inch of pillowy beige head that quickly disappears.
The aroma has lots of sweet and syrupy candi sugar characteristics as well as some bready malt, raisins and green apples.
The taste starts off with cherries, candied dates and figs upfront followed by a strong caramelized sugar malt backbone. There’s also a subtle and spicy yeast flavor in the background along with an assertive alcohol presence.
The body is silky smooth with active carbonation ( maybe a little bit to much carbonation , but thats the only - point ) and a dry, malty finish.
Overall, this is a GOOD quad , a rich and potent Quad that should definitely be split between two people.

12 oz. bottled purchased in the greater Washington D.C. area, 2013 vintage and best by 5/16/15 poured into a Delirium Tremens snifter, drank 10/31/13 over an hour

A: 2/3 - red-auburn coloration, moderate clarity (cannot see and read through), initial white rocky/soapy head on first pour resolved into 1/2 finger glass lacing with residuals clinging to the glass --> modertae-to-high carbonation for style; thick alcohol legs as expected for 10.5% ABV

S: 9/12 - Belgian-yeast stone fruit esters: plums, raisins, cherries, sour apples; small amount of Noble hop aroma

T: 16/20 - on the front of the tongue, there is a moderate sweetness as some fruit flavors - plum, raisin and apple; in the middle of the mouth, these flavors developed into impressible malt complexity with some alcohol complexity and Sytrian Goldings hop character for balance; impressively little aftertaste for the intense malt complexity

M: 4/5 - big, chewy body (provided by the high alcohol content); slightly high carbonation for style but makes the flavors pop

O: 9/10 - one of my favorite Belgian quads, which was validated by a blind tasting against some of the best Belgian quads (Westy XII, St. Bernardus, etc.), where this was my favorite; at 10.5% with the intense malt complexity, it's crazy dry, which I love; I also love that this beer is released year-round, which is awesome --> highly recommended!

TOTAL = 40/50

Poured into a Westmalle chalice a hazy brunt orange/light brown color with two fingers worth of foam that recedes semi-slowly, leaving behind some decent lacing. Candi sugar, yeast, candied fruit, and hints of caramel in the nose. Taste is fairly sweet in the front, flavor of cherry cordials, burnt sugar, some fruitiness, maybe some orange flavors that creep up and then disappear, some caramel, slightest hints of chocolate, some green hop character in the background, slightly spicy and peppery. Very complex, and that's definitely a good thing. Nice, creamy mouthfeel, but enough carbonation zip on the tongue that makes this one bright and extremely drinkable for the high ABV. Alcohol warming can be felt, but its fairly well hidden for the amount. A fantastic Belgian Style Quad. I've been impressed with the Smokestack series so far, and out of the three I've tried, this one has to be my favorite. Looking forward to the Bourbon Barrel Quad w/ cherries to come out.

Wow what a looker. Beautiful mahogany color with mouse like tan head floating above. One of the best looking beers I've ever seen.

Cherry, rum, toast, molasses, vanilla, and a bit of roastiness in the nose. Almost tart smelling.

Starts with those sweet candi sugar flavors that are rummy and little chocolaty. Cherry like fruitiness in the middle brings some tartness to the table and rounds out the sweetness a bit. Finishes bone dry with black pepper and nutmeg flavors.

Mouthfeel is wonderful because it dances on the line between extremely attenuated and full bodied. Another highly drinkable beer out of the smokestack series. I wish I could get these beers here in Central PA. Highly recommended.

S: Very malty caramel smell has kinda of a sweet note with a little bit of hops on the nose
T: At first taste was full of of sweetness and little bit of malt and hops. The second taste was a little less sweet and more hops.
O: Overall this beer was very awesome i had some of the smokestack series before and i'm looking forward to rating the rest including the collaboration with deschutes

Gigantic tight off white head sticks around for most of the beer. Nice amber cherry clear filtered color.

Very nice aroma. Cherries, tobacco, dark fruits. Nice warm spicy aroma comes on towards the back end.

The taste doesn't deviate far from the aroma just a little more complexity. A slight twang from the yeast. Cherry and dark fruit flavor melds nicely with a spicy alcohol bite. A bit of caramel is present. There is a lot of depth in this very nice brew.

Nice carbonation and creamy chewy body. Quite an alcohol kick. I'm a fan of this brew not quite on the same level as my love for the bbq, but very close. This guy stacks up quite nicely with any Belgian quad.

Thick, rich, with a bit of spice. Deep amber in color, with a nice head. First sip was exceptional as the carbonation seemed to enhance the spice. Smooth, with just a minor hint of bitterness at the end. Almost a perfect balance. Exceptionally easy to drink ( I tried to take it slow to savor it but it slides down the throat with the greatest of ease.)

A: Pours a ruby red color with a humongous three finger cream colored head that recedes quickly.

S: Both dark and light fruit vapors permeate from this brew, hint of banana, cherries, booze vapors, and some honey.

T: Cherries, raspberries, red apples, grapes, this is a bouquet of fruit. Touches of honey and various other sweetness, this is a nice one. A much more refreshing sweetness as opposed to the creamy sweetness of rochefort 10, another front runner of this type.

O: Very tasty. Glad I traded for it.

Extraordinary. That is my initial impression. Cant believe this Is above 10% abv...

I could go on for a 19th-century novel's-worth of characters about this brew.

Appearance is intriguing, with an inch of white head subsiding to a fine lace with a dark auburn hue to the brew.

Smell is satisfying, with banana up front with some date and darker fruits mixed in after

Taste leaves me wanting more, with a light effervescence and carbonation. Fruity & sweet with plenty of malty goodness to remind me I'm not drinking an alcoholic V8.

Mouthfeel is never too sharp, with all flavors being represented equally. 10.5% abv? Would not have imagined until consuming 3 or more of these puppies...

Looks brown until light reveals a reddish hue; small head that dies away quickly; aroma is delicate and inviting, with candied sugar, hints of banana, and even some nuttiness present; taste is simply impressive, making me wonder why I've waited so long to try this; the body is outstanding, I really can't recall ever having a 10% beer feel this light and bubbly; kudos to Boulevard! Back to flavor... Bread, caramel, maybe slight almond, bananas, milk chocolate--lots going on, making it hard to dissect, but easy to enjoy and appreciate. I'm really enjoying this and will certainly be buying it again.

Picked up this beer in MA, not sure if its available in NY. Awesome brewery. Poured a 12 oz best by 5/18/14 into an oversized Duvel tulip.

A - Pours amber and very hazy. A 2 finger pour with very light lacing

S - Definitely pick up on the dates and figs as described.

T - Sweet up front from the dates/figs. Pretty well balanced with a nice finish. The alcohol is well hidden by the Belgian attributes

M: Medium body, good carbonation. Good fell for a 10.5% beer.

O: Really good beer, highly recommended. Not a huge quad fan, but this beer is well done. It was definitely better as it warmed up. Go out and find it. Cheers!

12 oz. bottle poured into goblet

A: Good two finger, brownish head, retains very well. Had a good layer even after halfway finished. Dark amber color. Lots of yeast particles floating around though, eventually settling at bottom.

S: Lots of potent dried fruit (fig, raisin, etc.) smell. Slightly varied from Beligan quad aroma. A few boozy waftings (to be expected from a 10.5% ABV), but not distracting at all.

T: Very sweet and not at all bitter. Kind of malty, but enjoyable aftertaste in back of throat. Fruit from the aroma matches the taste perfectly. No hiccups, very smooth, and no big changes from nose to tongue.

M: Persistant head keeps creamy quality to the tongue but it is not thick at all. Despite retention of apparent yeast particles, if I couldn't see them, I wouldn't know or feel they were there.

O: This is the beer that you want to end a night out with friends with, either after a tasting or winding down from a night out to a show. Such a delightful beginning, middle, and finish. A fantastic American quad from Boulevard, a brewery that is quickly creeping into my higher echelon of breweries. Good non-Belgian variants on Beligan styles can be hard to find this side of the globe, and whenever I can find a example that both honors and matches up with its forefathers, I cannot help but bring it to attention. With beers like Sixth Glass, Tank 7, and Grainstorm coming out with fantastic results and increasing distribution, I look forward to expanding my brew-related flings with Boulevard and making it a regular part of my craft tasting rotation.

A - Pours a cloudy amber orange with a half-finger of frothy off-white head. The head fades fairly quickly leaving behind some lace.

S - Aroma is a mix of sweet caramel malts and caidu sugar, with some dark fruits, Belgian yeast, spices, some light fruits, and booze.

T - Starts off with some sweet caramel malts and Belgian candi sugars with some sweet figs, raisins, and other dark fruits. Through the middle, some deeper dark fruit flavor comes through with some Belgian yeast flavor and some spices. The finish is a mix of dark fruit and Belgian yeast esters and spices with some candi sugars and a bit of booze.

M - Full bodied with moderate carbonation. Feels smooth with a touch thick with a warming and sweet finish.

D - Very drinkable. Nice balanced Quad. Good balance of sweet flavors and Belgian yeast character and body.

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 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.
