Notes: ”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...

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

Bottled 5/24/16; drank 10/4/16 @ the Yarchives.

Opaque purple/brown appearance.

A rough pour yielded a HUGE, noisy, khaki head (careful pouring!); thick, frothy lace.

Raspberry, merlot & plum notes in the nose.

Medium thick mouthfeel.

Dry plum & mild merlot flavors up front; soft yeast notes on the finish.

Too dry to be really enjoyable, but at least it smelled nice!

Dark ruby color on the pour with a big creamy head and thick lacing. Aroma is heavenly sweet and taste has hints of caramel, dates and raisins. Finish is smooth but high ABV is evident....this brew has a kick, Top shelf brew at a decent price.

Not as malty, with a drier finish than I prefer for my boozy dark Belgian quad ales. Lots of clove notes stand out. Very solid, though not my exact style.

12oz bottled 7/12/18 BB 11JUL2020 poured into a Boulevard tulip glass at fridge temp 10.2% ABV 22 IBU. The beer pours mostly bright dark amber with substantial and lingering light khaki head. The head recedes to a 3/8" cap and leaves spots of lacing. The aroma is brown sugar with clove, date and raisin intermingled. The taste is semisweet and clovey amber malt with accents of raisin, date, cherry and sweet breads. Negligible bitterness, just enough to temper the malt. The mouthfeel is medium to full bodied with above average carbonation and a mostly dry finish. Overall, very good. A classic American quad for good reason.

oh, i like quaffing it well enough (leaving elaboration to others)... but just one caveat - from my own experience this is consistently one of the most explosive ales out there when uncapped - no matter how still or chilled, it's a guaranteed eruption. ("champagne yeast?" my one buddy theorized...)

So have your glass ready and over a sink beforehand, and be quick! utterly RABID! ;-)

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

From notes 9/8/12: Pours a hazy copper producing 1.5 fingers of off-white, finely bubbled foamy, somewhat lasting head that leaves little lace. Abundant carbonation rises from the bottom of the glass. Aroma is banana, sweet fruity bread, apple and pear with faint dark fruits. Taste is Belgian yeast fruitiness with bubblegum, dried fig, Belgian candy sugar, wood and alcohol. Finish is boozy sweet with a peppery bite that runs into the aftertaste. Mouthfeel is medium bodied with high carbonation especially up front, tongue coating sandpaper prickliness is a little hard and reduces the drinkability.

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

Appearance - crimson/amber body with off white head and some sediment floating around

Aroma - raisin, berry, yeast, clove, apple skin

Taste - apple, raisin, berries, clove, cherries

Mouthfeel - medium plus bodied, full carbonation, sweetness from the dark fruits upfront, bready in the middle, clove spice in the back

Overall - solid iteration of a Quad, flavors are nice and balanced. The color of the beer is a bit of a shock, but otherwise, this was a good beer. While I don' t think anyone would confuse this for St Bernardus Abt 12 or Westvleteren XII, Where other American interpretations fall short, this one here is worthy of a shot.

Price Point - $3.99/12 oz single

look: 4 | smell: 3.75 | taste: 4.5 | feel: 4.25 | overall: 4

Bottled 30.12.16, so almost at end of supposed bb, 2 years old.

Colour and foam unsurprising for a quad, perhaps a tad lighter in hue and lacier than avg. Indication of wheat in the recipe, the latter.

Aroma is very ..Belgian. Not particularly prominent, mainly dark fruits and lots of dark sugar.

Taste is the same, but much more assertive and balanced by some yeast-derived phenols and a bitterness that is almost unpleasant at first, of the yeasty kind, but once subdued, lingers pleasingly to cut the maltyish body. Long tail. Dark sugar all around.

Overall brings classic Belgians to mind, say Westvleteren XII. If I had to guess, I would say it's the same yeast and similar emphasis on sugar, just maltier.

25.4 OZ; bottled 2015; drank at end of 2018; roughly 3 years old.

Look: Beautiful


Taste: Just the right balance of malty goodness, bitterness and sweetness.


Overall: I've had a number of these now (most in 12 OZ bottles), both fresh and aged, over the years. This is perhaps my favorite Quad and more broadly one of my favorite Barleywines. I like to have this one on hand.

Dark, cloudy amber color. Just above average body with equal amount of carbonation
Aroma is a mix of candied dark fruit, raisin bread , yeast, and what i can only describe as a sugary floral smell
Taste is very similar with the dark fruit coming through first. There's a yeasty dark bread taste and the dark fruit flavor lingers awhile.
Overall this is first class to me and I will seek this out again

Roughly a third of a 750 mL bottle poured into a snifter. One-and-three-quarters of a finger of a very light tan head recedes quickly but remains accumulated at the edges of the glass. Color is a hazy deep amber. It’s almost chestnutty. The nose is a lot drier than I expected, and it is quite yeasty – it becomes a bit reminiscent of raisin bread when a tiny bit of spice develops. Perhaps cloves. The taste begins with a bit of peppery molasses, followed by a yeasty bread and spicy clove interlude, finishing with a punch of alcoholic warmth mixed with pungent caraway. Mouthfeel is a bit heavy and chewy, which, although unsurprising for such a strong beer style, I do not particularly enjoy. Overall quite tasty and does hide its 10.5% ABV quite well – very easy to drink for something so strong.

Pours amber. Smell is malt, peaches, pears. Taste is light caramel and malt. Peaches, pears and apples up front with more caramel in behind. Alcohol is well hidden. Hints of pepper in there. Good carbonation. Long lasting head. Gets better as it warms slightly.

Reviewed from notes. Poured from a 12 oz. bottle into a Tampa Bay Brewing Company snifter glass.

A: Pours a hazy orangish bronze with fairly low visible carbonation. Forms a two-finger foamy off-white head with average retention.

S: Belgian fruits (apples, sweet pears), with caramel and bready-sweet malts. Not a huge aroma, but pleasant enough.

T: Fruity sweet (apples and pears again, with lesser flavors of banana and a touch of clove). Yeasty and some ethanol sweetness under the bready malts. It finishes fairly dry with lingering fruit flavors and some alcohol burn. NOTE: As this warms during the drink, the flavors really open up.

M: Medium body with somewhat low carbonation sensation. The alcohol presence seems about average for style.

O: Note to self - this really needs to warm up significantly from refrigerator temperature. While the tasting notes remained largely unchanged, the flavors really opened up and became more rounded. Pretty darn tasty, though likely short of the world-class Quads.

look: 3.5 | smell: 3.25 | taste: 4 | feel: 4 | overall: 3.75

poured from a 12oz bottle into a goblet.

look: half inch foamy light tan head that recedes into a nice cap. the beer is a nice chestnut brown with garnet highlights.

smell: sugary, a little bit like raisins. possibly some hints of cherry. my first impression was sour apples, although it's more sour than apple.

taste: starts with a very lightly sour maltiness. the malt grows stronger, finishing with an almost molasses-like flavor. sweetness throughout. alcohol is well-hidden.

feel: good carbonation that retains smoothness but gives the beer a nice bite. leaves a little bit of warmth at the very end. nice and full-bodied, almost chewy.

overall: a very good quad. i'm a fan of the sweetness; it's subtle but still noticeable. i prefer the barel aged quad, but given the price point this is a nice alternative.

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

Look - Pours a cloudy dark amber. There's minimal lacing with a nice light brown quarter finger head.

Smell - Smells of strong sugar, with some caramel drenched raisins as well.

Taste - Extremely malt foward beer. Definitely a burnt sugar/caramel flavor and there is a fruity sweet undertone as well. For how sweet this beer is, it has some nice spice character as well.

Feel - This is a medium bodied beer, with surprisingly moderate amounts of carbonation. Thin but still has a slightly oily texture. The spice adds a nice little kick that helps subdue the maltiness of the beer.

Overall - Overall, this was a very solid beer. Malt forward with strong caramel backbone, cut by a nice spiciness that complemented the sweetness well. Definitely a top notch quadrupel.

Pours a slightly brownish orange with a finger of head and plenty of yeast floaties. The nose was a touch astringent and lacked the malty sweetness indicative of the style. The flavor notes that I simply love in a quad seemed to be absent - no prunes and raisins.

Boulevard The Sixth Glass Quadrupel, 10.2% ABV, 22 IBU. Pours dark brown with a four finger off-white head. Nose is malty, Werthers, and sweet dark fruit. Taste follows, moderately sweet, plus cherries, very slight bitter close, with a touch of alcohol burn. Excellent mouthfeel, overall outstanding. Not sure where the name comes from, but six of these and I'd be under the table. But I'm up for it.

Poured from 12oz bottle into glass. Best By date stamped on bottle is '09MAY2019'. Bottled on 5/9/2017.
Cloudy, medium amber colored body, with reddish highlights. Sediment in the glass. Permanent light tan head. Just a couple of spots of lacing.
Aroma of candy toffee, raisin, fruity yeast esters, and booze.
Taste brings forth the sweet candi sugars, dark fruit, green apple, cherry, sweet bread, and booze.
Medium mouth feel with tongue numbing.
All around this is a tasty quad.

From the small bottle in a snifter via a friend from work----Cheers Randy!
This fine brew that I somehow missed on reviewing in the past pours a beautiful
and glowing deep amber with a light reddish tinge and a fantastic head of light
pale tan foam that subsides to a thick ring, thin layer, and showcases some nice
light lacing. Nose of heavy candy sugars, figs, raisins, sweet cherry notes, sweet
yeasty bread, and hints of booze. Flavors nail it with a sweet Belgian candy sugar
note awash in layers of fig and raisin bread warmed by brandy like notes and
hints of sweet cherries and peaches that are lightly touched with an herbal hop
flavor. Excellent mouth feel with medium body, light carbonation, and a sweet
warming finish.

Overall one of my favorites ales from a great brewery.

Pours a deep red color with a LOT of sediment in the pour. Smells of fig, raisins, dark cherry, hint of brown sugar. The taste follows the nose very closely, with some booziness on the back end. There's a nice balance of the sweetness and fruity tartness. The flavor is very rich and the taste is awesome, though it's a bit boozier than I prefer, which seems to be expected for the style. I quite enjoyed it, though it's not something I could drink very often. I'm not familiar with the style, but I'm intrigued!

Clear and reddish brown with a giant tan head. The head clings to the edges of the glasses after it fades. The aroma has raisins, toffee, apples, sweet malt and fruity yeast. Tastes like burnt sugar, raisins, figs, apples and finishes spicy and a bit hoppy. This is a damn nice quad.

Poured from a bottle into a tulip glass. Rich mahogany color. Thick but short lived beige head, good lacing. Fragrant initial smell of slightly sour apples. A bit of a boozey taste, pears, apples, caramel. Rich sweetness. Very nice.
