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

Pours a hazy reddish brown with a persisting fluffy runaway head.

Smells spicy and yeasty. Tastes of raisins, plums and other dark sweet fruit with a cinnamony spicy finish.

Medium light body with medium carbonation. Light clean wine like mouthfeel.

Compares well with some Belgian quads I have enjoyed.

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

pours a deep amber brown body with a toasted cream froth foam head that has high retention and leaves patches of thick lacing as it settles to a murky hilly cap

lots of fruit in the aroma. dark cherry, plum, candied orange peel, fruit cake, toffee malt and oak.

taste follows the nose. little grainy tasting in flashes. brandy styled booze in the back. merlot grape musk shades.

high carbonation, medium body. booze heat with carbo prickles. heat spikes as it sits for sure. feels fairly thick and chewy and a little grainy at times.

the next bottle I get, I think I'll let it sit in a shaded place in the bottle for a year or two. the booze is the most prevalent that I can think of in the style as far as I've had so far. I dig the flavor profile a lot, but the overall feel of the brew keeps from the indulgence I've come to love in the style. maybe that's the devil in the detail that they're advertising, the thing that reveals itself only after the 6th that case, I wish I had 5 more to test the theory...maybe next time,
still an overall beautiful brew, especially coming from an American tribute....but I guess that's it...feels more like a tribute band than the real deal.

A superb brew...

...Right out of the glass the beer pour a very appealing color of dark copper, with a lighter hue and frothy to top it off. The smell is light on booze and has an even lighter caramel flavor. Mouthfeel is medium bodied, carbonated, and smooth going down. I noted hints of cinnamon, bourbon, and even some cardamon, but I'm not entirely sure. This was a very nice experience, kinda reminds you why you became a craft beer drinker...

Pours a deep amber. Thick foam. Mild sweet aroma. A nice fruity body with a bready malt finish. Really smooth considering the high alcohol content. An excellent quadruple just don't drink it fast.

Chocolate brown in color, and smells of fruit cake, and toffee. Nice flavors and sweetness is subtle with a slight boozy finish. Very easy to drink, and a perfect way to end a day.

Burnt orange with a generous head. Not very strong aroma of grain & spices. Interesting flavor profile: bread, banana, yeast, alcohol & spices. Moderately thick, with good carbonation & some alcohol flavor.

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

Poured from a bottle into a chalice.

A: Reddish orange, extremely hazy with lots of sediment dancing around, stirred up by the carbonation rising. Quickly dissipating head with large bubbles.

S: Dark cherry, plum, and oak. Some sweetness, almost like tangerine. Heavy overall and not unlike a barleywine. Alcohol is detectable.

T: This is where this beer really shines. Deep and complex, with a lot going on throughout the sip. More dark cherry and stone fruit, with a nice brown butter aspect. Tastes a little oaky as well, it’s like the taste is a much fuller expression of the nose. A bit of bitterness, sparring with a decent amount of sweetness. Definitely brandy-esque.

M: Mouthfeel is strongly warming and boozy. Yet somehow it’s somewhat weak due to the large bubbles

Drinkability (legacy): Very nice to have after a long day at work while sitting in the sun and thinking. Very alcoholic, so not sessionable.

Overall: Has some deficiencies in the body but overall is very pleasing and interesting to drink.

look: 4.75 | smell: 4.75 | taste: 4.25 | feel: 4.25 | overall: 4.25

Poured from a bottle into a chalice glass

Appearance – The beer pours a deep amber color with a red hue. Upon pouring the brew has a nice billowy tan colored head that persists for a very long time before slowly fading to leave a ton of foamy lace on the sides of the glass.

Smell – The aroma of the brew is huge of a delicious dark fruit aroma mixed with tons of lightly toasted malt. The dark fruits are mostly of plum and cherry, but there are others in there as well with some aromas of raisin and currents. At the same time there is a nice bit of coriander and clove spice as well as some yeasty and candied sugar aromas. Overall very inviting and delicious smelling.

Taste – The taste begins with a nice, somewhat more crisp in nature, lightly toasted mat taste. Along with these flavors come all the dark fruit that was sensed in the nose. The fruit is big of a cherry and plum flavor with some light raisin mixed within. Along with the fruit are the nice candied sugar tastes there were discerned in the nose. As the taste advances, the sweeter tastes fade ever so slightly with the toasted malt tastes getting a bit more pronounced. At the same time some yeasty tastes and some spice flavors of coriander, clove, and allspice come to the tongue. While the sweeter flavors fade a bit toward the middle of the profile, they surge again at the end with the dark fruit tastes getting rather strong. With a touch of warming alcohol that comes at the finish, one is left with a nice robust and almost soothing taste to linger on the tongue.

Mouthfeel – The body of the brew is medium in thickness and creaminess with a carbonation level that is rather average to on the slightly higher side. The feel and carbonation are great for the spice, fruit and sweet, all while keeping the drinkability in check.

Overall – A very nice quad with lots of great dark fruit flavors, enough toasted malt to balance it out, and just enough booze and spice. Quite tasty!!

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, it's surely delish and like quaffing it well enough - semi-opaque plum grape hue, yeasty & sweet nose/taste, bubbly tangy mouth - ... 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 been a guaranteed eruption every single time. ("champagne yeast?" my one buddy theorized...)

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

PS: quip from my good buddy - "why buy a beer you can't open?" (yes, it made a mess on him too upon popping)

4.09/5  rDev -2.2%
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.

4.24/5  rDev +1.4%
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.

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

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.

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.
