Notes: Bourbon Barrel Aged Imperial Peanut Stout. ​This creamy and colossal peanut stout is nuts. But, our resident archaeologist, historian, brewer, and professor...he's really nuts. Mad peanut science.

look: 3.25 | smell: 3 | taste: 4.25 | feel: 4.5 | overall: 3.75

Bottled June 2017, opens with a hiss. Pours black with dark brown highlights, more sediment in the bottle than expected. Very fizzy. Head is gone as soon as the glass is righted on the countertop.

Smells of dark chocolate and fusel booze, leaning almost nail polish. I'm sensitive to the gassy smell of alcohol, so I feel a bit bad about rating the smell.

Tastes much better. Dark chocolate fudge, bourbon, and a nutty flavor on the back. Tannic with lingering bitterness that reminds you it's a beer and not a chocolate liqueur. 

Smooth, creamy and rich, which takes me by surprise given the fizzy-ness. The sweetness gets to me by the end of the glass. The peanut(butter) stouts I've tried haven't captured the PB taste enough for me, and this one is no exception. Maybe it's an extra-difficult flavor to capture.

Overall I wouldn't spend the price to buy it again, but it was tasty while it lasted.

For those rare occasions that we are all torn between wanting imperial stout or peanut brittle, the fine Rocky Mountain brewers at Avery has let the altitude get to them. Their massively bold stout exceeds even the most imperial of stout and saturated it with peanuts and then in bourbon barrels for a unique, savory and decadent taste that doesn't seem forced.

Nuttiest Professor comes nearly still and with only a brief collar of creme. Onyx black and with a tar-like viscosity, the beer clings to the glass with its inky gloss. Lavish aromas of dark coffee, cocoa and high nuttiness carries a cookies 'n cream type of sweet scent underneath. Blackstrap molasses, espresso and bittersweet chocolates coat the front of the tongue as the first sip explodes on the initial tastebuds.

The nuttiness slowly rises through the middle palate as the palate acclimates to the beer's absurd strength and also as the beer warms to reveal more of its succulent nuances. Char, cocoa and light campfire all relax while the premiere taste of peanut brittle and Belgian chocolate intertwine on the senses; patiently awaiting a spice filled finish of kaluha, creme de cacao and unmistakable bourbon. The whisky barrels invite a smoothness of vanilla, caramel and coconut that finishes the session with oaken spice, vinous sherry notes and peanut skins.

Rich, lush and drinking more like a meal, the calorie packed density of the beer provides a soft chewiness that suggests that this stout won't necessarily pair with dessert, but rather replace it altogether. A long finish of booze soaked chocolate covered espresso beans and peanut M & M's continue to tease the late palate with notions of candied flavors from far ago, just all grown up.

Love peanut butter beers, but this will be my first aged in bourbon barrels, & I’m sweating in unmentionable places just thinking about it. Part of Avery’s pricey 12 oz. gold foiled bottle series, a few of which have been worth the bitcoin. Another? Bitte.

Pour is rainy night black with roughly as many bubbles as an asphalt puddle, then it quickly stops raining. Nose brings Reese’s Peanut Butter Cup, but lighter than expected. Unexpectedly, there is no alcohol or barrel up front. I hope it’s coming. Barrel is coming.

Nuttiest Professor deceives, because there’s plenty of what’s hidden/missing in the nose dancing atop my wiggling tongue. Strong peanut butter is both up front & then slips around everything else to provide a lovely, creamy finish. Sandwiched in between is a quick shot of alcohol, lovely bite of bourbon that strengthens as it warms, faint chocolate, big dose of malt sweetness that almost mimics maple. Big, warming, creamy (again) & though it’s a chore to drink, I’m glad I’m in a hotel room. My bed is almost within falling distance.

I’ve paid more than $15 to be touched where this beer is touching me, so I’ll rate it a good bargain. Heavy on the barrel, peanuts, alcohol, & horrible pun. That makes it excellent.

if they used the whole nut instead of some powder or extract for the peanut butter character, i admire that, and think that aspect of the beer is definitely a success. a lot of the nuts come though the big meaty base, and they really are the dominant flavor agent, but taste great with the bourbon too, which is heavy in this. that said, how much of this could anyone really drink, or how much would they want to? its enormous, super boozy, and sugary to boot. its better than a novelty item, i mean, this is as high quality and delicious as i could imagine something like this being, but its just so huge and diabetic, almost dangerous. slick black look to it, not real lively in the glass, just some patchy surface bubbles. aroma here is toasted peanuts with a nice dark chocolate element thats a great compliment. desserty with the molasses sweetness in here, but also rather earthy and natural, tons off flavor, with the nuts leading the way. its not oily or greasy like some of these can be, i think thats a real highlight too, and i keep tasting all the flavors for miles after the swallow, pretty satisfying and compelling. all the wood and bourbon in the end give it a fancy feel, sweet too, but so on point. its hard to be too negative about such a well executed beer like this, ambitious as can be, i just thought a few ounces was plenty. i could not think of a brewery i would rather have attempt something like this than avery, and they have done a splendid job! super strong, really interesting.

edit: this has changed a lot in a couple of years, 2017 bottle definitely seems to have faded as far as the peanut intensity, more obvious in nose than taste now, and with a cherry and raisin fruity aspect rising up in the middle instead. very little oxidation and the alcohol has mellowed some, but the decreased peanut aspect makes the bourbon really stand out. a nice stout, maybe more nuanced than flavored now in terms of the peanut, but its still worth drinking. i was unsure how this would age, dont have a lot of experience with nut beers in the cellar as its a pretty new phenomenon, and this has evolved a lot, maybe i liked it better fresh, but still enjoyed it with the crew this weekend as part of a lager avery bottle session. i miss these guys!

Incredibly surprised by this, I think it's the thicket BA stout/porter I've ever had from Avery. They are getting closer to to that world class mouthfeel, beers like islay, dui cochi, and uncle jacob's do not have it. I love that it's not translucent in my goblet with my iPhone flashlight pressed on the glass. Roasty peanut butter, sweet, with an excellent thick mouthfeel. I like that it's closer to 15%, and not 17-18% which usually is a bit too boozy even for me.

15.22% abv.
It pours black with a tiny amount of foam that dissipates quickly. Typical for such a high in alcohol beer.
That nose! Bourbon, peanuts, chocolate, dark pitted fruit, vanilla and caramel. Whew. That's the boozy part.
Nuts, man, bourbon, caramel, kinda toasty as well as roasty. Fruity on the back end towards the finish which itself leans to being sweet. Plenty of heat from the alcohol.
Here is one fine sipping brew!

Bottled 6/19/17; drank 9/18/19 @ the Yarchives.

Black appearance.

A rough pour yielded a small, noisy dark khaki head which quickly dissipated; no lace.

Peanut butter, milk chocolate & bourbon heat notes in the nose.

Thick, sticky mouthfeel.

Peanut butter & bourbon heat flavors up front; milk chocolate notes on the finish.

I aged this for two years hoping the booze heat would fade; no such luck.

look: 2 | smell: 4.25 | taste: 4 | feel: 4 | overall: 4

Pours an effervescent ebony with near zero head. No head retention & lacing

S: Chocolate, vanilla, faint peanut smell

T: Follows the nose, along with dryness & bananas up front. Some nice barrel notes mix with peanuts, banana, vanilla & some booziness once this warms. Finishes with a little peanut, some bourbon & a touch of banana

MF: Medium body, minimal carbonation, builds a little once warm, also slickens a bit

Drinks great for the ABV, some booze burns through in the end & makes me think I should have sat on this for a few years

Black in color with no penetration to light. There's no head, but there are some minuscule carbonation bubbles erupting on top. The aroma is of sweet bourbon and roasted peanuts. I'm tasting a very balanced flavor of roasted peanuts and sweet bourbon. The mouth is dry and warm.

12 ounce bottle, bottled JUN 19 2017. Served in a snifter, the beer pours dark brown/black with about an inch tan head that fizzled away really quickly. Not much lacing, either. Aroma is nice, it smells mostly like peanuts/peanut butter, along with chocolate, roasted malt, bourbon, vanilla, and a bit of coffee. I think the taste is similar to the aroma, with peanut/peanut butter, chocolate, bourbon, molasses, coffee, roasted malt and caramel flavors. Mouthfeel/body is full, it's slick and smooth with a moderate amount of carbonation. The 15.2% ABV is well hidden here, I really thought this was going to be boozier (although I'm sure it will catch up to me later). Overall I thought it was a good brew, glad I picked this up when I did! $13.99 a bottle.

The beer pours black as tar, zero carbonation. Very thick and viscous.

Peanut butter is really all I can get easily from this nose on this one. There's a hint of chocolate or just a darker sweetness, perhaps a light vanilla, but it smells like peanut butter.

I'm telling you this is peanut butter with a vanilla mid pallet with some bourbon notes, and then right back into peanut butter. Some kind of candy milk chocolate somewhat sneaks in here and there.

Man, darn good, but a bit one dimensional. I won't buy this one again at the cost of 12 bucks or a buck an oz. Still really nice beer, very glad to have had it.

Beer is black as night.. opaque. No head

Nose is thick, robust, nutty. Peanuts, chocolate, oak, Bourbon, vanilla, sweetness.

Flavor is much like the nose. Lots of peanut and chocolate upfront. The finish is a little hot with bourbon. There are notes of oak and vanilla too.

Super thick, low carbonation, and halfway between creamy and boozy.

Overall this is a great imperial stout . Big, flavorful, thick, and boozy.

look: Deep dark imp stout depth, sparse cola highlights when held to light. Almost no head on the pour and that recedes quickly. No lacing but an oily sheen coats the glass.
smell: rich, decadent and unique. Peanuts in rich molasses espresso.
taste: much like the nose. Rich decadent and perfectly crafted.

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

L: Poured from a bottle to a pint glass. Had a dark brown color and a thick texture. There was a small amount of foamy, tan-colored head that quickly dissipated. Not much lacing here.

S: A nice aroma of peanuts, malt, bourbon, and chocolate.

T: Tasted of a fair amount of bourbon (not as much as I expected), a tinge of chocolate, lots of peanuts, roasted malt, light vanilla notes, dark fruit (raisins), and caramel. Certainly not your typical stout flavor. On the whole, a solid flavor, but the peanuts and bourbon don't always seem to mix well. High ABV% is hardly noticeable.

F: A below average amount of carbonation with a super smooth finish. Medium- to full-bodied.

O: This is an unusual beer that has its flaws. Worth a look, though.

No.45 in the barrel series, bottled June 19, 2017: pours pitch black color with a 1 finger tan head that dissipated so quickly that so quickly I barely got to see the brown head form before it faded and was gone. Fastest Avery Barrel-Aged Series head drop yet.

Nose has everything advertised on the bottle: peanuts, bourbon, barrel accents like oak and vanilla, roasted nuts, and then it brought in burnt coffee grinds, molasses, soy sauce, cocoa powder, Hershey's chocolate syrup and bittersweet chocolate. It's on the border of cloyingly sweet smelling, but the bourbon influence keeps it in check and very complex.

Taste is just what I hoped for when I bought this bottle: bourbon, barrel accents like oak, vanilla and/or vanilla beans, charred wood, peanuts, roasted nuts, dark chocolate, burnt coffee grinds, molasses, soy sauce, cocoa powder, Hershey's chocolate syrup, toffee, brown sugar, bittersweet bakers chocolate, ashy notes and faint toasted coconut. This flavor has strong bourbon blended with burnt campfire marshmallows, cocoa powder, vanilla and trailing peanuts. It seems sweet until the bourbon jumps ahead of the sweetness and levels it out. The 15.2% ABV is always present but never a booze distraction, as this somehow seems balanced with a little bitterness and the nutty contrasting sweetness.

It's a little thin for an imperial stout, but it's so smooth and easy to drink that to me that aspect made up for the thin overall mouthfeel. I love the way this fades with bourbon, then dark chocolate, and then finally the peanut flavors. A damn fine slow sipper which may be too sweet for some people, but I am a huge peanut and peanut butter lover so this took two of my favorite things in life and blended them together. Worth trying as this is a craft beer gem.

I was very much looking forward to trying this release... but boy was I disappointed. Very little peanut flavor, not much barrel presence, timid booziness and a tad too tame overall compared to other Avery massive brews. What I like about Avery's limited releases is how huge and over the top they are; almost offensively unbalanced but oh-so-delicious. This one feels like an imperial stout with none of the bells and whistles.

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

Poured into a Fremont small snifter. Pours a very dark mahogany brown, appearing opaque black in the glass with a thin brown head that dissipates immediately into a faint ring around the glass with no lacing. Aroma of sweet dark toasted malt, peanuts, cocoa and bourbon; a little boozy. Flavor is semi-sweet dark toasted malt, molasses, bourbon, peanuts and mild cocoa, quite hot and with a bourbon finish. Medium bodied with light creaminess and light carbonation. The base stout is as good as I'd expect from Avery and the peanut component is well integrated. Unfortunately, this is a little to hot; the bourbon and ABV drowns out a lot of the more subtle flavors, as well as some distinct ones like the peanut butter and chocolate malt notes. It's fun to drink and the 12 oz. bottle is the perfect size, but it's one of those nice big stouts that I wish I could taste the nuances in flavor. I actually would like to try the base stout that this was made from, there's a lot of good, balanced malty and nutty stout flavors here. The good thing about big Avery beers is that for some reason (heh), they taste better and better as the glass empties. That's the case here. Nice, but needs to be reigned back a little to let the flavors show through.
