1 PINT 6 FL. OZ. bottle
Served in a snifter

This beer pours black and is topped with less than an inch of mocha head that leaves no lacing.

The nose is like dessert, caramel, vanilla, and chocolate.

The taste is rich with chocolate, caramel, and vanilla with hints of alcohol and dark chocolate and coffee in the finish.

Full and velvety smooth mouthfeel

This has held up well for four plus years. It is definitely one of the best barrel aged version of BORIS. The taste and smell are great, and I feel like a warm, fuzzy blanket is being wrapped around me with each sip.

2013 bottle into a shaker pint for a Super Bowl tasting. Pours an opaque black with a thin layer of light brown head that had good retention. Smell is enjoyable, chocolate, whiskey, and a hint of butter perhaps. Taste is a bit hot, but very enjoyable buttery smooth mesh of chocolate and whiskey. Mouthfeel is super smooth, carbonation spot on, and a slightly hot and boozy finish.

22oz bomber, green cap, poured into KBS snifter. Opaque, black elixir, thin rim quickly dissipates. Legs coat the glass.

Holy hell the aroma really hits home: smooth Jameson whiskey, vanilla, honey, char, cocoa. Swirl this and smell all night long.

Smooth whiskey, vanilla, cocoa, subtle burnt malt lingers. Really nice combo.

The base beer provides a nice smooth mouth feel with the alcohol well hidden.

This is my favorite treatment of the base BORIS and the whiskey combined with the smooth oatmeal stout brings it home. Well done.

The following written review is for my final bottle, enjoyed 9/7/2017.

Pouring squid ink black, Bairille Aois displays a moderate, dense mocha head that settles to a permanent collar, even after all these years.

Smell is peanut butter wafer, wet chocolatey oak, a touch of spicy, savory bourbon, roasted nuts, and a hint of molasses.

Taste is roasty, dark malt and peanuts with oats, molasses and black licorice but also simultaneously maple and candied pecans. It's so distinctly glazed pecans, it's insane and delicious, and a little smoky.

Feel is slick and a bit less thick than normal BORIS, but still luscious with a semi-dry, slightly sticky finish.

Pours thick, oily, and black. Smells lightly boozy. Tastes, oh my, tastes slightly sweet with a slight bitter coffee finish. Feels amazing. Thick, slick, but not syrupy. Just great. I would drink this again. And again.

Coconut, chocolate, oak, coffee and a hint of booze. Medium bodied. Super dry. It's pretty good. Barrel integrated well, balanced. As with most of the Hopping Frog beers, the Ohio restriction on alcohol percentage hurts the mouthfeel on this one. wishing it was just a bit chewier.

22oz bottle poured into a snifter

A- pours a motor-oil thick opaque black color with a small creamy dark tan head that retains for a while, eventually settling to a thin film floating on top

S- deep dark roasted chocolate malt aroma up front with a hint of char & dark fruit, big barrel presence that adds notes of buttered pretzel, vanilla oak & Irish whiskey

T- big flavors of dark chocolate malt up front with some nutty walnut notes, very light smoke, caramel, vanilla & barrel juice additions from the barrel, rich buttery finish with lingers of oak barrel and Irish whiskey

M- thick and viscous body with low carbonation leads to a slightly foamy mouthfeel and a warming finish

O- a nice variation on an already great beer, the Irish whiskey adds a nice buttery notes that surprisingly meshes well with the other flavors

Got this brew from Hotpipes a while back. Love the base beer, so really happy to see this barrel aged variant. Cheers!

From a bomber into a snifter
OG: 1.107
IBU: 60
Aged in Irish Whisky barrels
Tried this and BORIS van Wink back to back for comparative purposes

APPEARANCE: Pours out pitch black, like thick, sludgy motor oil, producing a two finger, medium looking, creamy, mocha colored head with good retention. Jet black body with next to zero carbonation evident. Head slowly fades to a full wisp and a creamy ring. A ring and splotchy wisp remain until the end but leave no real lacing down the glass. Very dark and menacing looking brew. Enticing.

SMELL: Decadence. No doubt. Lots of butterscotch, caramel and toffee notes, whisky, milk chocolate and sweet cream notes. Chocolate milk shake qualities are in there. Chocolate fudge with Werther’s Original butterscotch candies. Sweet cream and oaky wood aromas in there as well. Really beautiful.

TASTE: Also excellent. Butterscotch, whisky and oak notes up front, the some more chocolate and alcohol at the swallow. Big, bold and lingering finish of butterscotch and caramel sweetness, sweet cream and chocolate milk shake, whisky and oak notes. Some bitter chocolate fudge offers a nice touch of balance to all the sweet malt and barrel flavors. Alcohol and whisky are wonderfully measured as well. This is very flavorful and well balanced, but perhaps a touch too boozy for a perfect score.

PALATE: Fuller body with medium levels of carbonation. Creamy enough on the palate, goes down fine and finishes rather sticky. Enough weight for sure. Some heat lingers as well. Nice stuff here again.

OVERALL: This is outstanding. BORIS is fantastic as it is, as are the barrel aged variants, but this is probably the best of the bunch. This is just as good as BORIS van Wink, and if you didn’t know any better, the two variants could very well have come from the same barrel. I really must admit that with all the barrel aging and variants breweries do on their base stouts, the BORIS set is probably the best in the world. Bold, persistent and decadent flavors are supported by a big, thick and creamy feel, while the aromas and appearance make the opening act just as good as the closer. Excellent, and better than 99% of the BA stouts out there. Cheers!

Pitch black and creamy looking. Faint khaki head that completely disappears.

This smells like all kinds of baked goods. Sugar cookie, brownies, fudge, and coffee.

Coffee, cookie dough, oak, vanilla. The barrel flavors are modest but it works.

Velvety smooth, low carbonation. Heavy body.

A fantastic beer and worth seeking out.

The beer pours black with minimal tan head that settles around the glass's circumference with oily lacing. The nose is a carpet of barrel caramel over thick oat sweetness followed by hinting booze and a little spice. The beer's thick, rich, chocolatey, slightly roasty malts infuse well with the burnt wood vanillin and caramel in the beer's flavor profile. There is a bit of fruit/licorice in the finish, but roasted grain is what lingers. This is a chewy, full bodied stout with unquestionable barrel characteristics cutting deeply through the beer's sweet, roasty base. As the beer warms it has a bit more bite, but doesn't change significantly. This is definitely my favorite beer from hoppin frog, though not my favorite BA stout (mainly due to the abrasive mouthfeel).

Bottle to tulip.

A. Poured very dark brown. Fairly thin viscosity. Poured an excellent frothy fine bubble amber head that retreat to an impressive rim.

S. The nose has a layered malt/coffee/whiskey/oak presence.

T. A contrast between the malts and whiskey and the malts win. A bitterness follows indicating a hops presence. I notice the base stout. Heavy on the grain. A little coco and coffee. The whiskey (could have fooled me for bourbon) is certainly prevalent.

M. Slightly silky finish. Moderate carbonation. Uber full body.

O. Bourbon or whiskey, when its good your splitting hairs. Each is very similar to the other and this ale is similar to some dang fine bourbon aged stouts. This is a well crafted ale.

A: Pours a thick and black with a gradually rising reddish brown head. Good retention and some light lace with each sip. A good looking beer.

S: Takes a little while to get there, but once this warms up, it's pretty solid. Lots of heavily roasted malt, wet barrel, mild dark fruit, amaretto, whiskey and some cherry. The wood really starts to come through the more this beer warms.

T: Definitely doesn't have the sweetness that most bourbon barrel aged stouts have. The whiskey gives this one much more of an edge. Dark chocolate, just a hint of dark fruit, a thick pull of whiskey, a touch of toffee and just a bit of burnt espresso alongside some booze on the finish. Mouthfeel is maybe a touch thin, and this may be just a touch hot, but this is some pretty solid stuff.

Bottle shared with stillmatic 2232. Thanks man.

Pours a very dark black, basically opaque, into a Captain Lawrence tulip. Small head that fades away after a while.

Smells roasty, with additional mild flavors of whiskey and chocolate.

Tastes incredible. Subtle, creamy, almost buttery Irish whiskey, chocolate, caramel, vanilla, oak, mild roasty bitterness, and love. Normally I wouldn't love a "buttery" flavor in the beer, but I think it is intended, and it adds so much to the beer. It's most likely the Irish whiskey barrel aging. Adds a dimension to barrel aged stouts I've never had before. Love it!

Smooth and silky on the tongue. Great mouthfeel. Very drinkable for the high imperial ABV.

Very recommended!

look: 4.75 | smell: 4.75 | taste: 4 | feel: 4.5 | overall: 4.25

Poured from a 22oz bottle

A - pours dark brown, almost black with a thin, quickly disappearing tan head. No lacing

S - sweet chocolate aroma dominates. Hints of vanilla and oak from the barrel, subtle scent of whiskey.

T - front taste of dark chocolate. Bitterness is well balanced with a sweet okay vanilla from the barrel ageing. Strong/hot alcohol after taste.

M - thinner than your average stout (let alone a BA beer). Lacks that lasting mouth feel of a full bodied stout.

O - This beer has such great potential...a nicely balanced bittersweet dark chocolate flavor...that is hampered by an overly strong alcohol burn. The whiskey barrels add a wonderful vanilla and oak taste. Perhaps it would benefit from some cellar aging.

Poured from bottle into Hoppin Frog tulip glass...Date is 1/3/2014

Appearance- Completely pitch black, no color whatsoever. Very good looking khaki head that disappears within a minute.

Smell- Whiskey, vanilla and brown sugar right away. A malty/ maple scent is there but barely.

Taste- Bitter dark chocolate hits me right in the face. Strange, but I detect butterscotch secondly. This is much different from Hoppin Frog's traditional BA B.O.R.I.S.. I may be overestimating my palate, but I think I can tell this was aged in whiskey barrels and not bourbon.

Mouthfeel- It is much thinner then I had anticipated. Very unique experience in my mouth. With every sip I feel like my mouth is coated with dark chocolate. The whiskey is lingering in the back of my mouth and throat forever.

Overall- For the record, I am born and raised in the Akron area, so I am, as should be expected, an Ohio brewery homer. With that being said, I try to be as honest as possible while reviewing beers. Great beer from a world-class brewery.

Thanks to Wowcoolman for sharing this one at AndrewK's tasting.

Pours an opaque black with a foamy dark khaki head that settles to wisps of film on top of the beer. Small dots of lace slowly drip into the remaining beer on the drink down. Smell is of dark roasted malt, cocoa, cookie dough, fruit, and slight whiskey aromas. Taste is much the same with cocoa and fruity flavors on the finish. There is a mild amount of roasty bitterness and an alcohol kick on the palate with each sip. This beer has a lower level of carbonation with a slightly crisp and medium bodied mouthfeel. Overall, this is a good beer with a fantastic aroma but the barrel presence seems fairly subdued in my opinion.

Smell - Whiskey. Chocolate. Caramel. Doesn't really work that well thought.

Taste - Whiskey is strong. Chocolate. Very bitter. Kinda ashy. Uninspired finish.

Mouthfeel - Medium body. Carbonation makes it feel thinner than it is. Boozy and bitter.

Overall - Not a good treatment of Boris. Ick.

Poured pitch lack with a khaki head. Smell is sweet chocolate, oak, dark fruit, some cinnamon, marshmallow. Taste starts with slightly smokey bourbon, cinnamon, dark fruit again, plenty of chocolate. Texture is very enjoyable, silky smooth. Overall this is a great variation on the regular bba Boris. This is much less of an in your face bourbon flavor that you get from the regular bba version. The whisky flavor is definitely more complex and once you've had a few sips you can taste the Irish whisky in the aftertaste especially. Glad I got a few of these, especially with it being a brewery only release.

A: Thick black pour. Thin ring of foam and bubbles.

S: Barrel aged complexity. You catch the Chocolate, malt, vanilla etc. of their standard BORIS but the warmth of the irsh whiskey barrel it's been sitting in.

T: Everything's in its right place. You taste what your nose is picking up. The Irish whiskey gives it a milder more balanced barrel aged taste compared to you typical bourbon BA beer. This adds to balance of the beer though.

M: Full, rich and smooth. Not overwhelming. The BA aspect a seems to help the beer kind of coat you mouth.

O: By far the best Hoppin' Frog beer I've had. A little different because of the Irish barrels, honestly adds a briant balance to the beer. This could hang with most top notch BA Stouts.

Thyis bad boy is dark, nice and viscous on the pour. It acheives a full finger of tight, creamy tan head that rests on top for the session. It also shows some cling, depositing itself in patches on my snifter.
This stuff smells fantastic. The wood is there without doing too much to dry it, which shows expertise when using a dry whiskey. It's well enough attuned to allow plenty of sweetness to come out without being at all cloying. A nice, hearty barley undertone sets it all down. Vanilla comes out with the oaky wood with a touch of roast and cocoa. There's something reminding me of malted milk in here too.
There's so much complexity and depth in this big beer's flavor that I really appreciate the balance here. It's nice to have a bit of a creamy, buttery note I got underneath the other elements in the nose. To use a dry whiskey puts a spin on things, and Hoppin's Frog did it right. The heat and booziness are heady but not overwhelming, blending with the rest of the beer's flavor very well.
This beer is smooth, crushed velvet on the tongue but still thick. It's got some dryness lingering from the wood, to good effect.

A huge thanks to Denny at the Beer and Wine Cave for just breaking this out at the end of a tasting. Possibly my only chance to have tried it and amazing.

Big thanks to Sliverx and Markintihar for getting this bottle to me...

A: Pours a deep pitch black with one full finger of dark khaki colored head. The foam takes a little while to settle, yeah spotty lacing along the edges of the glass and a thin ring of bubbles along the top of the beer.

S: The nose is roasted malt, toast, milk chocolate, mild vanilla, a touch of caramel, and a good amount of barrel treatment. The whiskey is present underneath and it really adds to the complexity of the nose. It's not a vanilla forward or sweet and many other barrel aged beers.

T: It starts out with a mix of bitter roast/toast, chocolate, and whiskey barrel. I'm really impressed by the balance in the barrel treatment. The whiskey notes and vanilla notes don't overpower the base beer. You can feel the heat from the barrel, but it's just right.

M: Full bodied beer. It's smooth and coating, the flavors mingle well on the palate, and it slides off smooth. The barrel imparts some booze, but it doesn't dry the beer out or make it too cloying.

O: Really nice beer. This might be one of the best Hoppin' Frog barrel aged beers that i have tried. It's just really well done. I would drink this again in a heartbeat.

look: 5 | smell: 4.25 | taste: 4.5 | feel: 4 | overall: 4.5

Appearance: I like this a lot. This stuff has a thick appearance. I accidentally spilled some on myself and it looked as though I was bleeding stout (perhaps this biased my score a tad, but it was cool)! In the glass it was very dark and light did not pass through the glass.

Smell: Nothing out of this world. It is on par with most BA Stouts.

Taste: This is not a disappointment at all and I was worried because the age of the barrel is different for irish wiskey. I know that it doesn't have a lot of the tannens from the barrel because it was aged in an Irish whisky barrel, but the buttery whiskey taste along with the cocoa, oatmeal and tobacco are all present. Like others have posted if this ages well in the cellar and the flavors come together this bottle could become something truly remarkable. (I'll let you know in six months).

Mouthfeel: Even though this pours out really thick it did not feel very thick once I drank it. It was like the Irish wiskey thinned it out a bit. I really do hope it thickens out over time.

Overall: This was very good, and certainly better than regular BA Boris. However, I can't wait to drink some a few months from now (fingers crossed)
