look: 4 | smell: 3.5 | taste: 3 | feel: 3.5 | overall: 3.5

Testing this beer well chilled, poured from a bottle into a shaker glass.

A: A slight turbid, dark yellow beer, creating a pretty thick and foamy head when poured into the glass. When twirling the glass a lot of small bubbles appears beneath the foamy head telling you there should be plenty of carbonation going on in here.

S: A very hoppy smell appears at first, then turning into a little sweeter malty tones after a while.

T: The taste differs somewhat from the smell. The fruity bitter tones found in the smell can't be found tasting it, it's more of a after-bitter taste. I did expect a more balanced bitterness from the beginning to the end.

M: The long lasting bitterness is real nice. I did though expect a more bubbly&sizzling feeling from the appearance of this beer.

O: A powerful IPA loaded with nice bitterness. The downsides i find is that it is not that well balanced as i did expect, neither the bubbly&sizzling mouthfeel i get from the appearance of it.

My first stab at the BrewDog line of beers.Poured into a imperial nonic a clear bronze with a fluffy two finger white head that settled into a soapy-like mass.Big English malt and hop aromas,sweet biscuit intertwined with leafy/herbal hop notes with a tinge of iron.The flavors to me are dominated by English malt up front,lightly sweet and biscuity with that light iron/metallic presence,the hops come late with a herbal,"green" smack.If there was such a thing as a IEPA this would be it,pretty good.

I've had a few beers from this brewery and have been quite impressed. This one was not a let down either. The beer is a very clear amber color. The head is white and soapy, but it doesn't last long at all. The aroma has a very piney, citric (grapefruit and orange peel) aroma...lots of hops in this one. It's not one-sided, though, it also has a decided roasted and bready malt character. Good balance in the aroma (as well as the taste). The taste is predominantly bitter, with a great blend of hop and malt flavor. There's a little caramel flavor. Moderately sweet. Very firm mouthfeel and a medium body. The long and lingering finish is quite bitter. Good beer.

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

1 Pint 6.4 oz dark brown bottle. Freshness date stamped on back label.
Served in standard pint glass.
It pours a shiny coppery amber color with a big fluffy, though fast-fading off-white head. A fair amount of sticky lacing trails behind.
The first smell out of the gate is citrusy fruit cup, followed by barn grain and wheat crackers. A whiff of ginny alcohol is noticed in the background. A light floral smell seems to come and go.
A pink grapefruit bitter tartness leaps out. A minty herbal taste blends into the caramel malt backbone. A light taste of gin follows and lingers throughout as does a touch of a metallic tang.
The mouthfeel transforms from a slightly raspy cutting feel to a slightly fluid, nearly oily slickness.
All in all a nice Scottish take on an old English classic.
Pairs very well with sharp aged cheddar and salty crackers or pizza with the works.

Why is this still being sold at Bocktown for top dollar it's an English IPA, the label doesn't say what it is. I have a buttery/not hoppy ale from Scotland. WTF? Best before 8/16/10 Pours deep semi clouded apricot amber with a cream head forms fine bubbled with even lacing. Aroma has stale hops with hints of cardboard and caramel malt hidden amongst the old hops. Flavor brings on hints of butterscotch and spicy herbal hops, not bad actually. A strong pine bitterness almost resinous like amongst the faded hops there's still some strong hop bitterness and flavor. Not green but in this english style IPA the hops have acted as a natural preservative, this is probably closer to what the original was like. Mouthfeel is dry with bitterness medium bodied ale, any American IPA I've found this old is undrinkable and I don't feel this way about this offering. Overall impression I need to try this fresh but this beer is decent a solid EIPA. I will try more Brewdog because everything else I've had has been solid.

The beer pours a nice amber color with a thick frothy offwhite head that slowly fades to lacing. The aroma is decent. It has a complex malt aroma of pale, Carapils, and bisquit malts along with a mild hop nose that balances the aroma nicely. The taste is good. It has a smooth, malt centric flavor with a solid hop taste in the finish. It's got a fresh hop taste, but nothing over the top like most American IPA's. Instead, the malts provide excellent character and appropriate balance. The mouthfeel is fine. It is a full bodied beer with adequate carbonation. This is a good drinking beer. It's nothing exceptional, but it's full of flavor and easy drinking even at 7.1%.

330ml bottle, served chilled (in the same glass I've been using for all my beer notes over the last week or so, I will dip into the collection and change things a little)

It pours with a rich, slightly hazy amber body. Whispy off white head soon settling to a modest half finger.

Not a huge nose, English hops beefed up with an almost pilsner-esque Sazz aroma. A touch medicinal but only very slight, some fruity notes too but nothing overpowering

On the palette. huge biscuity dry lingering hops. A whack of quinine and grapefruit acidic notes, followed by a lasting pleasing dryness on the finish. Backbone of pale malt with a touch of alcohol too. Not big on aromas but hugely hopped bitterness on the palette. Some esters lingering around the mouth punctuated by bills, ballsy bitterness

Amber ale, or sort of IPA. Its in the style, its higher than average IPA, and so its above average bitterness for sure than your local British empire beer. Pours medium yellow, with some off-white head. Some citrus taste. Very drinkable, a bit of ageing helped.Above average mouthfeel.

look: 3.5 | smell: 3 | taste: 2.5 | feel: 3.5 | overall: 4

The colour is deep amber (25 EBC), the liquid is clear. The two finger off-white head is airy and uneven. Some lacing occurs.

The smell is strong. Alcohol, honey, sweet candy, harsh hoppy notes. Not much bitterness. Flowers, blackcurrant bushes and hints of cat litter.

The taste is first bitter. However, the bitterness fades quickly, leaving room for sweet flowery notes with hints of white currant, tobacco, unripe raspberries and old-fashioned butterscotch. Medium body. The aftertaste got some alcohol, toffee, hints of coffee candy and dry flowery notes. Some harsh hops and hints of lecture. Tobacco and pelargonium leaves in the finish.

The carbonation is medium strong, the small bubbles smooth and long-lasting.

A quite nice IPA, however I think it is more American/New World than English. I had a problem with the harsh dry notes that probably emerges from the dry hopping.

750ml bottle purchased as a single from Julio's, Westboro, MA. Batch 012, best before 8/16/10.

Poured into an imperial pint glass, formed a 1/4" light beige head over the slightly cloudy dark amber brew. Head is quickly down to an uneven layer of bubbles, with sticky slow-falling lace. Aroma is sweet and lightly of earthy hops. Taste is sweet upfront, lightly citrus in the middle, and closes with the earthy bitterness. Mouthfeel is soft and smooth, and drinkability is pretty good. Not quite the cutting edge in-your-face that I was expecting, but a good brew.

Coming in a slim 330ml brown bottle, BB 17/10/10, served lightly chilled in a straight pint glass.

A: pours a much darker hue than both Punk and Hardcore IPA - dark reddish amber in colour, coming with perfect clarity, mild carbonation and a thin layer of off-white foamy head.
S: like Hardcore IPA, the aroma bursts with complex tropical fruits - green guava, sweet pineapples, star-fruits, passion-fruits, plus pink grapefruits, rendered by both hops and fruit esters, while a close sniff reveals the presence of biscuity malts and nectar-ish sourness. Refreshing and remarkably juicy-fruity, without any trace of alc. actually, while the maltiness seems to be much milder on the balance
T: the interesting foretaste of tropical fruits, grapefruity hops and nectar is ever so juicy, then gradually hop bitterness sets in, leading to a long and semi-spicy chewy finish that is pretty high on alpha acid but relatively low in terms of hop flavour. It's also in the aftertaste that the sound toffee-ish maltiness makes a belated presence, helping to reach a balance with the chewy mouthfeel.
M&D: impressively bottled, the carbonation is only lively where it's needed, against a medium body and pleasantly light (not as imposing or heavy as Hardcore IPA) flavour profile. I've had Punk IPA on cask which is absolutely sublime, while I'd tend to imagine this one on cask can match Punk's performance or fare even better, due to the understated yet firm presence of the malt elements. At 7.1%abv., I simply fail to notice the alc. content - a vivid witness to the craftsmanship! Highly enjoyable.

330ml bottle bought from GapWines, Belfast..

Poured a nice bright clear coppery orange colour. Creamy head poured small but quite thick then faded to light covering with thick edging. Barely any carbonation... patchy lacing...

Aroma - Strong juicy fruits (oranges, apricots, pinepples, pears) mixed with a good pine hop note, lots of resiny sap, quite rubbery, cut wet grass, caramel and biscuit malts, herbal and light medicinal notes, faint alcohol whiff, hint of iron...

Taste - Overripe (tropical ?) fruits (pineapples, grapefruit, apricots, light melon), slightly harsh pine and citric hop bitterness, metallic notes, honey and caramel sweetness, light biscuity malts, peppery, some breadiness, quite floral...

M&D - Fairly smooth with a slight syrupy note then a little sharpness... light / medium bodied... pretty quaffable for 7.1%

Overall - A pretty decent IPA although there are one or two off flavours... worth a try..

Pours a remarkably frothy head, off-white and long-lasting. The liquid is a lightly hazed bronze color, and only small, thin wisps of lace are left on the glass.

Aroma is very much to style, but of course with the usual BrewDog twist. (Wouldn't be a BrewDog brew if it didn't have some kind of twist in the structure.) The nose receives a nice dose of musty, buttery, semi-sweet toffee-like malt, with a little bit of butterscotch coming in as well. Hop presence is merely subtle, with the malt being more upfront than a typical IPA, and there's your twist. A malt-forward IPA. Great!

Flavor brings everything in that could be expected from the aroma, although it's a bit more bitter, even leaning on the metallic/steely side of bitter. Not in a bad way. Lotsa grapefruit buried under the malt. Everything is nicely balanced and earthy. Malt sweetness remains toffee-like and slightly burnt-tasting. Hops are grassy, citrusy and bordering on astringent. Butterscotch remains from the aroma, and the hops exert a nice green snap throughout the finish. With all that, it's the malt that remains the most impressive feature, as with the aroma. The malt serves as a savory, fairly complex anchor in what is a pretty big-tasting beer, never veering into the waters of messiness or, ironically enough, chaos.

Feel is a light, airy sort of thing, not thin or watery but certainly having the kind of incredibly easy glide that makes it too easy to drink too quickly.

I always enjoy the esoteric, even existential ramblings on the BrewDog labels, and I'm a definite fan of these guys in general, all their boundary-stretching and button-pushing is a good thing as far as I'm concerned. Chaos Theory is true to style, yet one that takes the road less traveled anyway. Nice work, fellas, this is intriguing.

22.4oz Bomber
Batch: 9
Best Before: 08/16/10

Poured into a chalice a nice golden orange color, some carbonation, nice little fizzy off-white head, with some sticky lacing left behind. The nose is malty, very slight hop, some citrus. The taste is malty, some hop notes, sweet, bitter, some citrus. Medium body. Drinkable, a tasty brew, but was expecting more.

24.4oz brown glass pry-top bottle. BB 8/16/10.

Copper/amber with a thin white head. Aromas of biscuit, fruity yeast and citrus hops. Palate is clean with lots of British style fruity flavors and a crisp, bitter finish. Tastes like a great ESB or an extreme English IPA. Pretty good, not my favorite from the brewery.

Shared with a good bud, thanks for the bottle.

Off to the review...

Appearance was nice...a solid amber color, nice one-ish finger head on a mildly aggressive pour.

Aroma of malty hoppiness. A bit of a honey sweetness in the mix as well.

Flavor is definitely more bitter/hoppy than anticipated. I mostly get a strong bitter flavor over anything else. Not really picking up many other flavors.

Mouth is a bit chewy, especially as it warms. Develops a syrupy quality as you go along. Not a bad thing, just a bit different for an IPA.

Overall, a solid, drinkable IPA with some pretty bitter qualities. Alcohol probably prevents it from being sessionable (or maybe just the bitter), but still a solid offering from BrewDog.

In a pint glass this beer was an orange/amber color. It had a medium off white head, and a fair amount of lacing. Sweet malt aroma, very floral, and a bit of citrus. I caught more grapefruit in the taste, some pine, and a nice malt backbone. Slightly oily mouthfeel, balanced. Nice beer.

A - Deep orange golden in color. Nice head but turns to film fairly quickly, however left some fantastic lacing.

S - Fruity, grapefruit and tropical fruits, sappy pine needles, honey and floral notes.

T - Very similar to the smell. The fruits all hit you at the beginning with a nice clean bit of pine hops. The hop flavor escalates to a pleasantly bitter and flowery grapefruit rind all the way to the aftertaste.

M&D - Very smooth and easy to drink. The carbonation is Excellent for a bottled beer. More full bodied that many IPA's but not heavy by any means. I can (and will) drink a couple of these. My favorite Brewdog IPA.

Poured into a pint glass from a 22.4 oz. bottle. Slightly cloudy amber color, nice thick tan head with abundant lacing.

A nice malty caramel aroma, some piney hops in the background. Also light citrus character with a touch of spice. Aroma is malt forward, not unexpectedly. Taste also is earthy malt first, some caramel, hop flavor is minimal, mostly spiced citrus in nature. Big bitterness in the end though, as the hop bite hits hard and lingers for quite a bit.

This beer is a touch thin, good carbonation and certainly a nice drinkable English IPA.

Thick head, hazy, orange hued copper.

The aroma is like a yeasty sourdough starter with fruity and earthy hops.

Sweet, fruity, earthy. Brown sugar, apples, honey, grapefruit and grass. Sweet biscuit toward the end with a bitter hop aftertaste. Lighter than one would expect but the mouthfeel goes well with the mix of flavors. It's a tasty beer and interesting for an IPA.

With all this news about BrewDog, I decided to try some of their beers out. (Marketing worked?! Actually, I have thought about buying their stuff before, and now that it showed up at my local store, I figured I'd give them try)

This bottle is larger than the one in the photo, 1 pint, 6.4 fl ounces. No batch #, best before 8/16/10.

Pours a nice bright and clear orange color with a solid white head.

Aromas are of brewed tea, cereal grains, and hints of citrus.

Flavors are good, and not overpowering. Some brewed tea up front, as well as soft creamy and toasted malt flavors. Finish is a bit dry, with an earthy hop bite.

Mouthfeel is nice and full, pretty smooth, but not overly heavy.

Drinkability is good. Pretty solid English IPA. I like how the malts and the hop flavors are nicely balanced. Pretty good stuff, I'd happily drink another one of these.

Third BrewDog beer of the evening, poured into my lovely 'Judas' glass, almost a full year of life left according to the label.

Murky dull, deep, old gold/muddy terracotta coloured body with an off-white head on top.

Smells of hops and more hops, maybe a hint of malted barley in there too.

Good hoppy taste, not over the top, just heavy on the hops. The ABV is feelable and sits well within the taste and structure of the beer.

Could do without some of the condescending blurb on the label, but the beer is very good.

Pours a brown color with honey hightlights, a rather small and whispy head that dissipates into a light ring. Aroma is of toasted malt, fruity, caramel, and a light floral hop. The taste starts off with a bready malt, has a weird sour spiciness, honey, mineral water and some herbal notes. The hop flavor has some tropical fruit notes, piney with a touch of resiny bitterness. The brew has a moderate body with semi-soft carbonation; starts off sweet but finishes bitter. A malty AIPA for sure, though not overly so. Seems like a dirty AIPA since there are quite a few flavors from the malt. The hop profile is nothing special. A unique take on an AIPA.

22.4oz bottle into a Duvel tulip at Flying Saucer pours a crisp dark orange with a decent khaki head that lasts and leaves spotty lacing on the glass. Aroma is a decent balance of sweet malts and funky hops. The taste is funky bitter hops up front with a nice malt backbone, very interesting and unique, quite tasty. The beer is medium bodied with a slight alcohol presence. This is a very enjoyable, unique beer.
