330ml bottle

A- Very dark brown (almost black). Just a hint of hazel colour head that dissapears very quickly, leaving just some little lacing on the glass

S- Dark chocolate malts with some roastiness to them, a faint spiciness underneath to bring some life

T- Dark chocolate is again dominant, though i'm also getting some light coffee notes. Some vague spiciness on the tongue and a nice warming feel from the not completely hidden alcohol

M- A bit thinner than usual in body. Soft, though maybe a little even, on the palate; prickly with spicies on the tongue. A lot of pepper in the aftertaste

O- Warming but not as flavourful or complex as other strong stouts. The pepper aftertaste gets really too strong and annoying and seems to be hiding the other flavours: i feel like this beer is not perfectly balanced

look: 3 | smell: 2.5 | taste: 3.5 | feel: 3.5 | overall: 3

A. Poured a very dark almost burgundy black. Huge 3 finger head that dissipates quickly.

S. Not a whole lot going on here, maybe a hint of pepper.

Taste/Mouthfeel: Tastes very light in viscocity with an almost cream profile which is instantly neutralized by the chili pepper incorporated into the beer. Once the beer heats up a little bit (temperature wise) you can definitely get a little more bite from the pepper.

Overall: An average imperial stout, the 8.2% is hidden extremely well, not even a hint of booziness to it. Price point would be the reason I would say to skip over it, $6.99 for the bottle.

A: Pours a dark ruby brown, pretty much black. One finger of mocha head, decent retention, solid lacing.

S: Dark roasted malt with some sweet milk chocolate in the finish.

T: Coffee is definitely prevalent up front. Some darker chocolte and roasted malts come in. The chilis are mild, some spiciness in the finish but not overwhelming.

M: Full-bodied, smooth, light carbonation.

O: Very solid brew that I'd buy again, balanced and nice mouthfeel. Flavors are not as robust as truly "world class" stouts.

11.2oz. bottle served into a snifter

Pours a dark chestnut brown. It isn't quite black, but it's getting there. I got next to no head on my pour, but I was able to coax out about 1/4 of a finger of khaki foam. It laces in spots like Morse code.

The first thing that I notice on the nose is a slightly sour, kinda acrid malt note that is reminiscent to me of some British Porters. There's definite coffee grounds in here too. A bit of char of some kind. Maybe I'm only saying this because I know that its brewed with chile peppers, but I smell some roasted red pepper here as well. There's an essential red pepper flavor, nearly "fruity," as well as some charred skin. There's just a twinge of the heat that other beers brewed with chilies tend to have in their aromas. This does not at all smell like an Imperial Stout, as the beer's label claims it to be. But it is interesting and on-point as far as a Foreign/Export Stout goes.

The taste is quite unexpected. I didn't really smell any chocolate character at all, but the flavor is mostly milk chocolate. This is a chocolate bomb, truly. Milk chocolate for days. There's also a bit of red bell pepper flavor, and a small tingling sensation from the chiles that comes across like Big Red chewing gum. Maybe some coffee on the finish. Verdi reminds me of a less-complex version of Mikkeller Chipotle Porter. It's certainly in the Foreign/Export Stout category. Hell, if it was labeled an Imperial Porter than no one would bat an eye. It's pretty tasty -- enough pepper flavor to make keep the milk chocolate in check.

It's got a thinner, more Porter-like mouthfeel. Smooth carbonation. It works with the flavors, and that's the reason I'm scoring it a 4.0 instead of a 3.5. Overall, this is a fine, fine Foreign/Export Stout. It's tasty and easy-drinking. Is it worth purchasing? No. I paid $10 for this 11.2oz. bottle. Why do Italian craft beers have to cost so much? It isn't worth $10 but it is pretty darn good. If you're a big fan of light-but-flavor-packed stouts then you will enjoy this beer as an occasional treat. It's too expensive to make it anything else.

Poured from a 11.2oz into a North Coast pint glass...

A - Pours black with a two finger brown head. Head does not stick around for long, and there is not much lacing to be had...

S - Coffee, a touch of spice, and a good amount of roastiness...

T - Chocolate, coffee, and dark roasted malts. Lots of roastiness to be had. Finishes on a hot chilli note. As the beer warms the spicy finish becomes more apparent. This one is tasty...

M - Medium bodied with a moderate amount of carbonation. Smooth and easy to drink. Pretty much what you would expect from the style...

O - I really enjoyed the spicy finish. Good tasting brew, but not worth the money in my opinion. Payed 10 dollars for 11.2oz bottle. Glad I got a chance to try this, but probably something I won't be revisiting in the near future...

Cheers...

Poured black with a tan head, and thicker in the foam than expected. Smelled like roasted coffee. Flavor was more complex with dark chocolate, roasted malt, coffee, and alcohol. Slight alcohol warming in the finish. Overall a fine beer, but very hearty. I'm no expert on the subject, but shouldn't this be a porter?

So I woke up this Saturday morning and absolutely destroyed my to-do list. What's a guy to do but celebrate completion of a plentiful list of soul-killing banal minutiae with a delicious beer from the Greenville Beer Exchange? Nothing. That's what. There's nothing to do other than that. At all.

A - Poured from a bottle into a snifter. Pours molasses black with no highlights, some sediment, and a medium-thin, tightly foamed khaki head. The head dies away to leave a creamy film atop the beer and a ring of tiny bubbles around the glass.

S - The aroma is sort of forward-malty, with a little bit of dark chocolate, hint of coffee, and some solid wheat/barley notes. No sign of the hot chilis.

T - Pretty standard chocolate/cocoa, roasted malt, slight acidity stout flavor, but with that chili edge. There's a definite, reserved chili edge to the flavor that is a shade more prominent in the aftertaste. I wanted to call it sort of a capsaicin flavor, but a quick check shows me capsaicin has no flavor. So just a chili flavor then, not the active ingredient in aforementioned pepper. HEY, IT'S CHILI.

M - Just a tinge thinner than a lot of your stronger stouts, but that seems to work.

look: 4 | smell: 4.5 | taste: 4.5 | feel: 3.5 | overall: 3.5

A- Beer gives its presence known with a bit of gusto. Solid retention time with many miniature bubbles creating the appearance of a solid mass, but its a falsehood. It actually is interesting formation of a two phase system. We have tiny bubbles stagnant on the bottom holding up a singular mass of cream. Coloration is that of a sienna brown. Low amount of carbonation viewed from the edges in this inky darkness. Not too much going on in terms of perpetuating the mass. There is a good amount of sticky lacing as the froth recedes.

S- Perfect amount of roasted grain. Its the aroma of baking bread wafting from the oven throughout the house. Following that is a tad bit of the acrid nature of burnt grains bringing it full circle to the heat of the chili. Light spicy nature like smelling too close to a jalapeno. Brings a bit of zesty chili spice to memory as well.

Maybe some cocoa, not exactly sure if that is the sweet nature or not. Could be a false aroma.

T- Opens with a moderate hit of roasted and mostly burnt grain. Quickly fades away to the middle where the true monster lies. A quick burst of chili heat that never corrupts the flavors. It doesn't burn, it doesn't saturate, it doesn't overwhelm. It is how chili is designed to be in a stout. As this slowly fizzles the finish perks up which is almost entirely chocolate. Awesome hit on the end of milk chocolate, sweetness, and chili memories. Not the spice or heat, just the flavor of a chili pepper. Great work on this.

M- Undercarbonated. It truly needs more carbonation. It has a medium build, but that is because it is a tad syrupy at times. The finish is great with lingering potentials. Thin sometimes, and for an 8% I wasn't really overwhelmed with alcoholic characteristics at all.

D- I like this beer a lot. It has some errors in the tactile areas, but it hit a solid double for smell and taste. I wonder how it would have been if it was much fresher. I never stopped drinking it. As it warmed, it began to get sweeter and sweeter. Reminding me more and more of a milk stout with a lactose sweetness rather than sucrose or malt.

Oddly shaped 33cl bottle into wine glass. Very dark with minimal, chocolatey head and ok retention + lace.

Interesting smell with chilis in the nose, some sweetness, vanilla, malts. Awesome.

Despite the cool smell, taste is pretty straightforward. Roasted malts, chocolate, a brief hint of chili in the back of my throat as it goes down.

Full-bodied and perfectly carbonated. Low drinkability however, I definitely prefer other stouts.

A-Pours a jet black with one and a half fingers of medium brown head.

S-Smells of rich and deep dark chocolate with maybe a hint of some chili.

T-Rich and sweet dark chocolate with a small hit of chili and finishes dry and slightly bitter with lingering, yet mild chili notes.

M-Thick and rich with a moderate amount of carbonation with a slightly dry finish.

D-Really easy drinking for a chili Imperial Stout. The chili is faint enough for the less spicy tolerant out there while the rest of the beer is a really solid, delicious stout.

Presentation: Poured from a pry-top bottle into a tulip glass. This bottle was purchased in Italy and brought back in March of 2010 so it has a little over 6 months of aging on it.

A: Dark black liquid with a one-finger thick tan head. Reasonable lacing with respectable head retention.

S: Roasted malts with notes of cocoa and some slight sweet berry notes. Very little hop presence. Fairly decent for a stout, though the berry notes are a bit odd in my opinion.

T: This one has definitely mellowed out a bit due to the age. There is quite a bit of dark roasted malts with a pleasant amount of bitterness. There are some slight notes of unsweetened cocoa. There is a noticeable heat after you swallow which is due to the cayan peppers added in this beer.

M: While rolling the liquid around in my mouth there is a very nice silky feel in the mouth. As you swallow there is a significant dryness in the mouth.

D: This one can be enjoyed slowly but this is not what I would consider a session beer. Its enjoyable but certainly not as drinkable as some other stouts.

Notes: I really enjoyed this beer when I had it Italy and it was pretty decent now. I don't think having age on this one is a good idea; it should be drank fresh in my opnion.

My first stout from Italy- very cool.

A- Body appears to be a dark brown, nearly black hue-but when held up to the light it glows and murky translucency comes forward. Pours with a 1/2 finger milky head.

S- Dark chocolate is dominant with very faint chili in the nose and a mild roasted malt background that gives off the impression of coffee.

T- Initial flavor is mild and offers cocoa, smoke, and roasted malt with a very faint accent of chili. The flavors intensify for the finish but remains pretty consistent all the way through-with roasted malt and chocolate being the highlights.

M- Carbonation is low and body is moderately thick.

D- This is a very good, easy to drink brew overall. The chili and spice are very faint all the way through and provide a nice compliment to the chocolatey stout in the background. This is a classy, not over the top, well done brew.

A-very dark black color with a creamy tan colored head.

S-the nose is very cake like, chocolaty and creamy, light roasted malt with a hint of pepper but extremely faint in the back.

T-the flavor isn't quite as savory, a little thinner, notes of chocolate cake but light, hints of smokey malts and some light roasted malts in there, hint of coffee, slight note of licorice and pepper in the back.

M-creamy medium to light body, decent carbonation, creamy finish.

D-the body is slightly thin, the flavors are also slightly thin, nicely integrated pepper flavors, very light which i actually prefer. decent stuff.

Picked up a bottle of this one at West Lakeview Liquors. Shared with my wife, and served in a Night of the Living Ales taster pint.

A - Porus wiht a finger of light mocha foam that settles to a thin cap and thicker collar. Body is a near-black that reveals some reddish transparency at the fringes.

S - Big cocoa and roast malt aroma, with a hint of chili peppers that clears the sinuses. There's some faint smoke and a noticeable coffee note that emerges as the beer warms up. Alcohol is very well-hidden.

T - The taste is much more burnt malt oriented, with notes of smoke and char. There is some nice balancing cocoa sweetness, and perhaps even a hint of vanilla (or lactose sugar?) The finish is a little peppery, but doesn't come across as excessively spicy or hot - I'm not sure I would have got "hot chili" from the taste alone.

M - OK - first thing I notice isn't technically "mouthfeel", but this beer makes my eyes water. It reminds me of when I'm cutting peppers and inadvertently rub my eyes. The body is medium, and seems about right for the 8.2% ABV. The finish has a peppery dryness to it. Carbonation is surprisingly high for an Italian beer, meaning it is medium-low. Some definite heat builds over 6oz or so.

D - This is really good. It's kind of like Hunhapu's Lite. If it weren't so expensive I'd get it more often. Also among the best Italian beers I've had. Pairs well with Verdi's Macbeth.

A - poured into wine glasses. Very dark, nearly black, small tan head, moderate lacing.

S - baker's chocolate, chili powder, vanilla extract, charcoal. Doesn't sound too unusual but trust me it's complex and interesting.

T - also complex, but quite different. Slightly bitter from start to finish, in a good way. Chili only comes out at the very end. Even the primary chocolate malts are subdued vs the aroma, in favor of the burnt, almost peaty flavor.

M - has definite weight, though not super heavy. Best part is it's super oily and sticky.

D - all of the above, coming in >8%, yet very easy to drink in my opinion. One of the first really well crafted Italians for me (many others have showed promise but ultimately disappointed).

Appearance: very dark black with a thin tan head swelling up in some areas.

Smell: diffidently a dark chocolate malt aroma is the most powerful smell,

Taste: the first thing I got was a good dark malt, after a fair number of simps the chili came through, this como worked well for this beer.

Mouthfeel: complex in my opinion, a little oily and light-ish, a little heavy and dark, very interesting and pleasant overall.

Drinkability: it's a very drinkable beer, however, if your not expecting the chili it will sneak up on you a bit.

(Served in a snifter)
A- This beer pours a jet black body with a creamy tan head and a some floating lumps bumping against the glass then hiding back in the body. There are a few tiny bubbles stuck to the base of the glass.
S- This beer has a soft chocolate malt aroma with a dry roasted barley note to follow. Otherwise the aroma is pretty clean. There is a dark nougat and raw grain aroma that grows as the beer opens up.
T- The cream dark malt flavor is soft with a bigger roasted bitterness in the finish that has some capsicum heat to it. The heat grows and the bitterness fades as the beer opens up and the malt flavor starts to fade a bit aswell.
M- This beer has a medium mouthfeel with no alcohol heat and a gentle fizz in the finish. There is a very light chili heat in the finish but it doesn't linker.
D- This beer has soft flavors with a big finish that could use a bit more malt support. The heat is subtle but all burn and not much chili flavor. My mouth wasn't hot but my lips started to burn just a bit after the last few sips.

Bottle purchased at Healthy Spirits in San Francisco, CA. I don't see a bottle date anywhere.

Poured into a 7oz. snifter.

Appearance: Pour yielded a tall, thick, cake-like layer of brown foam. Beautiful! Body is pitch black and muddy; looks very thick. The huge (initial) head takes awhile to calm down, but it eventually settles as a creamy film with thick outer ring (and it maintains its gorgeous brown color). Thick, sticky lacing. No faults here.

Smell: Roasted barley, oats, dark chocolate, and a touch of "hot chili." Chili, caramel, and barbecue sauce pick up steam as the beer warms. With time, leafy greens and milk chocolate also emerge. I wasn't too wowed by the aroma at first, but it really comes to life once it warms. I dig.

Taste: Mocha, dark chocolate, oats, and "hot chili." I absolutely love when brewers and chocolatiers combine dark chocolate and spicy peppers. Mmmmm... so good! The chili oils really cling to the palate, making each sip spicier than the last. In this instance, the chili peppers actually outshine the roasted malts and hops in the aftertaste. That's cool with me - I love spice - but I'd actually prefer more balance between beer and chili. Still very good.

Mouthfeel: Cool, creamy, and malty upfront; spicy, oily, warm, and dry in the back. Soft carbonation adds a pleasant, massaging aspect. I really like the transition - it's very unique.

Drinkability: A bit too much heat. It's not that I couldn't handle it, but the pepper drowned out the other flavors and really inhibited my taste buds. Will I buy this again? Maybe. It was definitely a fun experience. If you're a fan of chili-infused stouts, then this one's a must! If you're sensitive to spice, you might wanna pass.

Rush to Map Room to try this bottle.

WOW, I learned 2 things tonight. 1. finally found an oustanding Italian beer, and 2. there is chili stout out there that is a poor mans Hunahphu... A black pour with a medium tan head, good retention and lacing...The aroma starts off sweet as mostly just chocolate. As it warms it really evolves bringing out some really nice pungent chili. It really is balanced and goes back and forth from chocolate to chili, each whiff is something new...The taste is awesome. Chocolate sweetness with a little chili kick at the end. This not ony has the flavors of chili but doesn't actually bring the heat. The heat is felt especially on the feel, after a bottle my mouth is tingling. This is just great all around.

Rush out and try to find this beer.

Yummm-OOO!!! Right up there with the very best Italian brews. Poured with a huge, brown, foamy, frothy, thick, sudsy head that lasts a long time, and lots of lace. Color is as black as my heart and just as opaque too. Aroma is malt, roast, coffee, cocoa, bare hint of chili pepper, and hint of dark, ripe fruit. Flavor is the same with the chili pepper coming out briefly at the end and then fading again. Body is mouth filling and carbonation is perfect for the style. Finish is like flavor. Delicious beer.

Pitch black with 1/2 finger of mocha colored head. A little lacing

Smells a little like coffee, some chocolate, and roasted malt.

Intially I taste mostly coffee, chocolate, and roasted malts. The finish is roasty,hoppy, and then at the very end, spicy. The hot chilis add another dimension to this beer. Im diggin it.

Mouthfeel is thick, chewy, and creamy. Medium carbonation. Appropriate for the style.

Drinkability is good. The hot chilis definitely make this beer more interesting than your run of the mill stout. However, this beer is not worth the $10 I paid for the bottle.

Bottle: Poured a deep pitch-black color stout with a large foamy head with deep dirty brown color head with good retention and some lacing. Aroma of deep roasted malt with coffee notes. Taste has also loads of character with great roasted notes and some deep coffee notes with some dry black chocolate notes also noticeable. Body is quite full with great smooth texture with great carbonation and no apparent alcohol. Very well done with load of character though still easily drinkable. Nice mix between a cappuccino and an imperial stout.

I must admit that I bought this beer simply because I liked the shape of the bottle. Anyway, it comes out completely black, with a couple fingers of tan heading. The nose is of dark chocolate, chillies, and not much else. The chillies are not as much pronounced in the flavor, more aiding in the path of the dark chocolate. Body is medium to heavy, and luckily very drinkable. I tried Cigar City Hunahpu recently, and this is definitely the closest thing I have found to it. They really use the chillies to a point where they compliment the chocolate, and do not overwhelm at all. Verdi is an excellent stout that I recommend completely.

Raddest possible bottle pours a clear dark brown with a thin light-beige head. Earthy milk chocolatey aromas, roasted malts, licorice, not much pepper in the nose. Flavor is dark chocolate with a spicy chipotle-like finish. The heat is mild but respectable. A little thin-bodied and oddly clean on the finish. I guess I can't expect a huge monster stout with 7-8% alcohol.
