Notes / Commercial Description:
This deliciously dark treat is our bold Narwhal Imperial Stout aged in oak Kentucky bourbon barrels. Black as midnight, this intense stout is incredibly complex with notes of dark chocolate, rich roasted grains, and espresso seamlessly blended with hints of vanilla and toasted coconut with a slight touch of honey from aging in the oak spirit casks. Nearly as rare as its nautical namesake, try it out while you can because, like the creature itself, it will disappear into the blackness soon and leave nary a trace behind.

Additional Info:
Narwhal was aged for 8 months in fresh bourbon barrels (a combination of Willett single barrel, Heaven Hill and various Beam brands).

Bottle shared at the monthly bottle share held at Flask Fine Wines in Studio City, CA.

Pours an opaque black with a foamy dark khaki head that settles to wisps of film on top of the beer. Tiny dots of lace form around the glass on the drink down. Smell is of dark roasted malt, cocoa, black licorice, bourbon, and wood aromas. Taste is much the same with cocoa, vanilla, bourbon, and wood flavors on the finish. There is a mild amount of roast bitterness on the palate with each sip. This beer has a good level of carbonation with a crisp mouthfeel. Overall, this is a very good beer with a bourbon barrel aging that adds well to the base beer.

Serving type: bottle.

we are approaching perfect with this one, and beer rarely ever does for me. this is extraordinary, and absolutely delicious. i am amazed how the barrel mellows the base beer, but how the unique flavors of narwhal come through the bourbon is incredible, not covered up by whiskey but enhanced by it. there has always been a little vanilla finish to the base beer, and that really comes out on the nose of this one, along with bakers chocolate, melting fudge, honey, and vibrant oak. there is the vanilla and chocolate complexion in the flavor too, but theres also a whole lot more, the coffee notes of the malt, and a burning dessert bread sort of thing, followed by moderate raw sweetness and just a tickle of alcohol. i do get a little coconut when i look for it, but there is a different kind of nuttiness here, more of an almond thing, almost creamy with the earthy side, works so well with the heavy bourbon flavors the beer finishes with. texture is amazing too, viscous but not syrupy, palate coating but not teeth rotting, and hearty but not filling, its a mix of sensations not usually associated with the style. this may well be my favorite barrel aged stout right now, and is certainly the beer of 2015 for me here in the early going. wow, go find this one and open it immediately, no need for cellaring at all its ready to rip!

Incredibly powerful, yet full of grace- Sierra Nevada's Barrel-Aged Narwahl is woven into a seamless bourbon cocoon. And with wine-like tones, the Stout is so much more than just roast and booze.

As the beer is delivered to the table, a quick swirl seems to encourage the Stout to crawl around the glass on its own, trailing with inky legging as much as it does a scattering of lace. Its mocha-stained sheet of foam is creamy but loosely knitted together, eventually succumbing to its massive strength.

Its bold and fragrant aromatics lead with obvious roast overtones. Smooth like espresso, dark chocolate, roasted nuts and a hint of dark fruit. As the sweet bourbon notes release caramel, vanilla and weathered wood, it also highlights its floral, plumb, berries, grape and overall vinous, sherry-like tones. Warming a bit, its citrusy hop character pull from the roast and booze in a surprising turn before that first sip.

Its masculine sweetness wraps around the tongue with those espresso and bittersweet chocolate malts like fudge and chocolate-covered espresso beans. Hearty sweetness of burnt toffee and molasses supports the roast character to near perfection. Its bourbon infusion delivers a plethora of complexity at middle palate- vinous sherry, charred berries, dates, figs and plum that's pulled together by the natural caramel wood sweetness, vanilla, mature oak and cherry wood spice. Turning assertively bitter in finish, only the slightest grapefruit taste discerns its hop-derived bitterness from charred bitterness.

Its certain full and chewy body uses its embedded carbonation to give a marshmallow texture to the mouth. Its creamy sweetness dissolves in stride to give its finish remarkable semi-dryness without harsh astringency. Lingering with espresso roast, bourbon warmth and a wisp of campfire- the Stout is perfect as after dinner digestive.

Where the standard Narwahl is formidable in its own right, the bourbon aging really pulls out the fruit, floral and hop tones as much as it provides complexity of barrel, booze and controlled aging- savory inducing taste.

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

Appearance: Pours the color of starless midnight but leaves a galactic pattern of lacing; the head recedes to a film rather quickly, however, but can be resurrected with a swirl

Smell: Roast and oak, buttressed by chocolate, caramel, coffee and Bourbon tones

Taste: The Bourbon is nicely integrated with the roast, chocolate and caramel tones with vanilla and toasted coconut developing; in the middle, there are touches of coffee, graham cracker, cinnamon and some hoppy bitterness; a lively warmth builds, after the swallow; with all of the flavors coming together in the finish

Mouthfeel: Full bodied with moderate carbonation and some warmth in the gullet

Overall: A bit of aging in my cellar has served this beer well, with all the flavors merging nicely

(Reviewed from notes)

BOTTLE: Brown glass. Bomber format. Branded cork. Generally appealing label art.

Reviewed as an imperial stout per the label. Served cold into an Odell stem-tulip at high altitude in Fort Collins, CO. Expectations are above average; I'm not big in the original Narwhal and I'm not the Sierra Nevada fanatic everyone else seems to be.

No bubble show forms as it's poured.

HEAD: 1 finger wide. Khaki colour head. Creamy, thick, and full. Soft-looking. Retention is average – about 2 minutes. Leaves no lacing on the sides of the glass as it recedes.

BODY: Opaque solid black – pretty much what you'd predict, but not an ink black or anything. Clean; no yeast particulate or hop sediment is visible.

Overall, it looks apt for an imperial stout, but is far from unique or special looking. I've definitely seen far better in the style.

AROMA: Dark malts, chocolate malts, cream, and caramel. Barrel-wise, I pick up on some faint coconut, but no rich toasty evocative oak. There's a mild vanilla presence. It isn't as woody as I'd anticipate given the barrel aging.

No yeast character, overt alcohol, obvious off-notes, or hop profile is detectable.

Evokes a fairly balanced brew without much barrel character. Definitely seems more interesting than regular Narwhal. Seems a bit too sweet.

Aromatic intensity is moderate.

TASTE: Boasts interesting notes of faint toasted coconut, mild vanilla, and a kiss of bourbon. It's missing toasted oak barrel and barrel sugar notes. Dark malts and chocolate malts comprise the simple foundation. Comes off a bit too sweet, but it's not quite boozy. Some caramel.

No yeast character, overt off-notes, caramel, or hop profile comes through.

It's decently balanced, but leaves much to be desired in terms of complexity/intricacy, subtlety, and nuance – especially considering the style – which demands that a lot be happening, at least to set it apart.

Average depth, duration, and intensity of flavour. Decent flavour amplitude. It's nicely built, with some loose cohesion, but never comes off tasting like a gestalt whole.

I do like it, and it's certainly more interesting than regular Narwhal, but I still expect more from a barrel aged imperial stout – especially in today's oversaturated market.

TEXTURE: Smooth, wet, full-bodied, unrefreshing, lightly boozy, somewhat soft, fairly moderately thick and overcarbonated. Overall presence on the palate is nice but wanting. This texture doesn't elevate the beer and doesn't feel custom-tailored specifically to the taste, but it suits the taste decently and doesn't hold the beer back.

Not oily, gushed, astringent, harsh, rough, scratchy, or dragging on the palate. It does have a noticeable alcohol warmth, however.

OVERALL: Definitely an improvement on the base beer, but still ultimately underwhelming considering the style. There are far better beers available in the style for less money, but this is decent and I do enjoy it. Sierra Nevada continues to fail to impress me, but I'm glad I tried this once. Unfortunately, the barrel character just never melts into the base like it should. A nice stab at the style, with a good premise. The toasted coconut stands out, but is too subtle in my opinion. More drinkable than a sipper, but by no means easy to drink.

Bottle: Poured a pitch-black color stout with a large dark brown foamy head with good retention and some lacing. Aroma of nice dark chocolate notes with some bourbon and vanilla notes. Taste is a great mix of black chocolate notes with some roasted malt notes and some bourbon notes and vanilla. Body is full with good carbonation with some light warming notes of alcohol. Not bad but I was expecting even more complexity.

Tan head. Black in color.

Rich and roasted. A fair amount of bourbon with a touch of heat. Lots of chocolate. Roasted malts. Oak and caramel. Molasses.

Medium bodied for a stout. A bit too much carbobations. Ends with bourbon and roast.

Solid offering from SN. Well done, but a bit expensive.

750 ml bottle into snifter, bottled on 10/16/2014. Pours dense pitch black color with a 1-2 finger dense dark tan head with good retention, that reduces to a small cap that lingers. Light spotty lacing clings around the glass, with a fair amount of streaming carbonation retaining the cap. Aromas of big dark chocolate, cocoa, coffee, molasses, caramel, toffee, toast, vanilla, coconut, bourbon, oak, light dark fruit, light butterscotch, and roast/oaky earthiness. Incredible aromas with awesome complexity and balance of dark/roasted malt and bourbon barrel notes; with good strength. Taste of big dark chocolate, cocoa, coffee, molasses, caramel, toffee, toast, vanilla, coconut, bourbon, oak, light dark fruit, light butterscotch, and roast/oaky earthiness. Light herbal/roast/oaky bitterness on the finish; with lingering notes of dark chocolate, cocoa, coffee, molasses, caramel, toffee, toast, vanilla, coconut, bourbon, oak, and roast/oaky earthiness on the finish for a while. Incredible complexity and robustness of dark/roasted malt and bourbon barrel flavors; with an insane malt/barrel balance and zero cloying flavors after the finish. Light-medium carbonation and full bodied; with a very smooth, creamy, silky, and lightly slick mouthfeel that in incredible. Alcohol is extremely well hidden with only a slight alcohol warmth lingering after the finish. Overall this is a world class barrel aged imperial stout. All around insane complexity, robustness, and balance of dark/roasted malt and bourbon barrel flavors; and very smooth to sip on for the huge ABV. A truly mind blowing offering.

2015 edition.Pours jet black with a stiff half finger deep beige head atop that never really settles.Caramel and butteriness to go along with bourbon and chocolate notes in the nose.Just full and smooth in the feel department,alot of richness.The richness is prevalent on the palate as well,rich vanilal and butter notes from the barrel to go along with chocolate and dark fruit,not much roast wich is good it might intrude on the softer flavors.It's damn good,the alcohol creeps a little packing some heat after awhile,but the feel and the flavors are top notch.

(from bottle)
Probably would benefit from some aging: could be softer and less boozy. Still, a fine strong ale with a well balanced contribution from the BBL.

Rich and moderately complex. Mildly bitter.

Great aroma.

Very dark brown with a light foam and o lacing at all in the wine glass. Spritzy on the tongue. Wonderful nose of booze and cocoa.

Tangy and sugary. Hot with alcohol, which doesn't seem to be the case with the regular Narwhal. Classic sweet yet burnt flavor, rich and hoppy, deliriously aromatic. Fairly dry finish as the heat burns the tongue and the rich dark caramel melts in the mouth.

Overall, I'm not sure this is any improvement over the regular Narwhal, which I like a lot. But there's a lot of Bourbon flavor to like. From the 750 ml bottle purchased for 21 bucks at Beer Revolution in Oakland.

Pours like sludgy motor oil, ebony with a thumb of hazel colored head& plenty of effervescence. Viscous, below average head retention & even less lacing

S: Carob & dark fruit, some port notes, molasses & licorice

T: Follows the nose, sherry & bourbon notes up front, raisins & figs as well, warming booze as well. Some chocolate & vanilla, dryness, slight leafy & woody hop presence & a little molasses as this warms, raisin as well, some red grapey notes too! Finishes with vanilla, oaky notes, red wine notes, a little herbal/woody hop counter-balance & just a little dark chocolate & just a little figgyness

MF: Thick, restrained carbonation, warming, carbonation picks up as this warms

A well put together barrel aged version of the style, much to love here! Well worth buying, a lot of flavor, ABV is well hidden & drinks very easy, all things considered

I enjoyed this bottle chilled in a stout glass recently at our annual stout tasting.

The color is black with beige cream and fine bead with moderate lace stickage. The smell is a mix of light woody barrel aroma with a nice level of malt roastiness and slight caramel accent with bourbon adding to the aroma and light spice in the nose. The feel is great rich malt with subtle sweetnes and mild dry woody quality with bourbon adding a mild alcohol element to the texture.

The taste is great with the stout base that is slightly spiced with hops yet a noticeable vanilla type flavor from the bourbon barrel aging that brings out the chocolate flavors in the malt with some light dried fruit and hints of molasses. This is the stout I enjoyed most of the several we shared I just found the bourbon to be very expressive without neglecting the Narwhal's great base flavor it is a great stout that is only enhanced by the bourbon barrel

From NOTB notes from last month; had a few samples of this one and liked it a lot.

a - Pours a pitch black color with two inches of thick tan head and moderate carbonation evident. Looks great, just like the normal Narwhal.

s - Smells of roasted malts, bourbon, vanilla, bitter chocolate, toasted malts, burnt malts, light coffee. Awesome nose; really nice mix of sweet bourbon, vanilla, and chocolate.

t - Tastes of sweet bourbon, roasted malts, oak, vanilla, bitter chocolate, dark fruits, toasted malts, and burnt malts. Very nice again, though I liked the nose a little better. Little more fruit and bitter chocolate here.

m - Medium body and high carbonation. Thick and smooth, definitely doesn't feel like 12.9% ABV. Nice mouthfeel.

o - Overall I liked this one a lot; I had high hopes for this after having the base beer and this did not disappoint. Looks great, great mouthfeel, and an awesome nose full of swete bourbon and vanilla. I know they are different beers, but liked this one a lot more than the BA bigfoot. Hoping to see this one again sometime.

Near black opaque body with a small, oily, beige head. Bourbon, oak, roast aromas. Char and smoke in the flavor with a formidable whiskey presence. Lots of oak and barrel presence. The beer is getting a little better as it opens up. Wet wood and warming alcohol. Pretty tasty.

On tap at River of Beers. Served in a snifter.

Appearance - Black body. Medium khaki head.

Smell - Bourbon is strong. Dark chocolate. Sharp oak.

Taste - Dark chocolate is the strongest flavor. Oak secondary. Moderate sweetness amd chocolat flavor. Never quite dark and bitter. Always a little sweet.

Mouthfeel - Medium heavy. Medium carbonation.

Overall - I expected greatness. I got a high quality beer. I think prefer regular Narwhal.

Narwhal is a pretty solid brew on its own. The idea of barrel aging it seems like a no brainer must-try.

Poured from a corked and caged 750, the brew appears black in color with a mocha head. The nose is much sweeter smelling than the base beer as it picks up plenty of essence of vanilla, caramel, coconut and toasted sugary notes. There is also a woody appeal to this mingling with whiskey and a fruity almost raison essence. The taste brings all of the above, whiskey warmth upfront and center stage, raisony fruity quality, slight roasty char, than all soft barrel including caramel, toffee and vanilla.

This is a solid offering that is bold and enjoyable, I could see myself sipping on this again if the opportunity presented itself.

Bottle from Colonial Spirits
Solid opaque black color with a decent sized tan head that has some retention and lace. Aromas of chocolate, caramel, light brown sugar, oak with a hint of bourbon and vanilla and just a hint too much cardboard. The flavor is big roasty chocolate with hints of caramel vanilla and oak. Light dark fruitiness with a pleasant warming alcohol that lasts long into the finish. Medium body with a light level of carbonation and a silky creamy mouthfeel. Nice sipper, I enjoyed it for a couple of hours. I would have liked a bit less cardboard especially with the enormous price tag this bottle came with. Nice to try but I probably would pass on this in the future.

Damn. This is how barrel aged stouts should be. It's mildly hot, but not enough to damper the ride. Nice woody boozy tones. Smooth stout flavors with a nicely robust edge. Great beer. Could deal with a lot more of this Awesome stuff.

Poured on tap at Pizza Paradiso Dupont DC into a small snifter. From notes.

Super dark walnut black body, can't see even up to the collar head. Tan collar with thin bubbles and very opaque.

Classic bourbon barrel nose. Lost of soft vanilla, sweet caramel, and sense of oak depth. There is no heat coming off of this at all.

Palate hits with a wonderful thick caramel richness. Roast charring malts and oak complete the aftertaste. Vanilla washes all over the palate with good depth. Body is a little fizzy strangely, detracts from the flavor a bit, just a bit too much carbonation, but still allows everything to be enjoyable.

A solid RIS that took a barrel real well, this could be the start of something big. Possible future BCBS killer or just an easier one to drink?

Poured from a cork and cage 750 into a snifter, the beer pours jet black and oil thick, with a fluffy, tightly bubbled brown head that quickly settles into a sparse surface coating. Aromas of rich chocolate, heavy sweet cream, vanilla, roasted coffee, hints of char and wood, and bourbon highlights. Flavors are amazingly balanced, with rich cocoa nib and sweet vanilla cream blending perfectly on the forward tongue. Wow! Highlights shine through as the beer cascades over the taste buds, with caramel, roasted coffee, tangy crème, subtle char, and spicy bourbon all peeking in here and there. There is a subtle warmth building as you drink, with the smooth, rich, velvety body layering itself over your palate and slowly sinking in everywhere it touches. The aftertaste is rich dark chocolate, cream, and coffee, all blending together in a magnificent linger. Smooth, layered, velvety soft finish that lingers perfectly. This is a tremendous beer!

750 ml bottle. Deep black body with a tan head that settled into a thin ring. No real lacing. Aromas of chocolate, cocoa nibs, whiskey soaked oak and some roast. Lots of roast on the palate with the chocolate making a center play, too. The oak and whiskey cask are on the back-end. Thick mouth feel. Enjoyable.

Everything its reported to be, and more. Pitch black with beige\ruby foamy head. Nice smoky aroma, wood, roast malt, burnt toast, some alcohol that singes the nose hairs. Taste is a bit mellower, lots of alcohol warmth, more roastiness, lots of wood. A sipper...

Wow! My 2500th review for BA; it doesn't even seem possible. It was hard to pick something great that I had never tried and it came down to this and Anchorage Deal With the Devil, both highly reviewed and sitting in the cellar. Tough call, but I went with a brewery that has never let me down and has always been in my top 5 favorites. 2014 bottle, properly cellared.

Poured into a Fremont small snifter. Pours pitch black, opaque in the glass and a thin light brown head that is persistant and leaves nice lacing. Aroma of dark toasted malt, light chocolate and bourbon. Like the base beer, this has a surprisingly light aroma, but a good one. Rich flavor of dark toasted malt, choccolate, coffee, light oaky vanilla and very nice bourbon. Finishes with well balanced chocolate malt and bourbon flavors. Medium bodied, a bit lighter than expected from a barreled RIS. A beautifully balanced imperial stout with everything I expect and want. The bourbon is up front, but does not dominate the other flavors. Very smooth and integrated. I had to taste this several times trying to detect any booziness and it's not there. Warming, but ABV well covered. This seems to have less char and smokiness than the base beer, and although I liked that, it is not missed here, there's plenty of complexity to keep this interesting. This was a perfect choice for this BA milestone review. Thanks Sierra Nevada! Keep them coming.

Bottle purchased at Nathaniel Square Corner Store in Rochester, NY.

Pours the darkest of dark blacks, really just impenetrable to light, with a dark mocha colored tan head, about 2 fluffy, creamy inches, and a lot of lacing.

Smells just decadent and heavenly- big, sweet and slightly spicy bourbon, tons of vanilla and marshmallow, and chocolate.

This tastes great, it almost feels like a Bourbon County light. It's so vanilla heavy, I'd almost think it was made with vanilla beans, but it's obviously not- it's all from the barrel, which is great. There's a bit of coconut too, and rich fudgy dark chocolate, along with some slight cookie dough flavors. The bourbon is definitely there, it's slightly nutty, a bit peppery and spicy, and sweet, all at the same time. As the beer warms up, some astringent wood flavors develop, and the alcohol makes a taste presence. At all temps, the alcohol is unbelievably warming, but never gets overwhelming. It's quite easy to take this whole bomber on my own.

This is really creamy, and has a full, rich, and high-class mouthfeel. There's a lower but present amount of carbonation, and a pretty thick body.

This is an exemplary barrel-aged stout, and I wouldn't expect anything less from Sierra Nevada at this point.
