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.

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 330ml bottle with a BB of Aug 2011 (batch 232). A predictably random IPA - purchased quite a while ago but hopefully still in good condition.

Poured into a Sam Smith's pint glass. A hazy orangy-amber colour with good carbonation and plenty of visible yeast sediment. Yields a large head of creamy white foam that lasts for several minutes before subsiding to a decent surface layer. Smells hoppy, with lots of pine and citrus notes underpinned by light malt and earthy yeast aromas. Pretty good...

Tastes of light malt with considerable aromatic hops and a decent bitter finish. Notes of pine, citrus, grapefruit, dry yeasty esters and a spicy bitter quality. Mouthfeel is quite light, with tingly carbonation and a pleasing hoppy astringency. Aftertaste of bitter aromatic hops.

Very nice - a first-rate effort from Brewdog. More American IPA than English, but stands up to the US-brewed American IPAs that I've tried so far. The flavour is fantastically hoppy without being overwhelming, and the mouthfeel is excellent. Would definitely recommend this, although I'm not sure if it's still in production.

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.

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.

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.

This bottle has a best before date of 18/06/10. This is actually my first brew dog beer. Has a dark coppery appearance and a great malty smell. no long lasting head as described in other reviews. Its malty upfront and bitter in the end but the two don't get confused. Carbonation is lacking and it is a little syrupy which is not to my liking but otherwise a great beer.

pour is light ruby with orange and copper. light cream colored head, light foam, light lacing and retention

faint floral and bitter hops. a bit of booze and light malts. would like some more hops here

nice and very balanced. bitter hops are there throughout but not a smack in the face. light pine and citrus grapefruit through the finish. malts are a bit light with a light read flavor.

has a nice body, nice and heavy with a bit of chew. as for an IPA, this is damn near perfect.

this is my first brewdog ale and i am impressed. it has that UK IPA with an american twist. super easy to drink and a lot of fun. ABV is a bit high, that was my only complaint.

Picked up a 22 ounce bottle of this stuff because iv Never had Any of brew dogs stuff and this one for some reason caught my attention.
Looks are a dark copper thing with NO head what so ever.Also no carbonation from the looks of things.
The smell is extremely biscuity, like all i smell is biscuit and iv never smelled that in any kind of IPA.Big time malts are also present and taking stage.Hops are mixed in but play a very minor role in the scent.
Taste is sweet at first followed by hints of pear and apple. Then bitterness ensues and lingers around for a while.
Refreshing mouth feel on this one! Unlike most IPA iv had its not over whelming at all and not sticky. In my opinion the mouth feel is one of the best aspects of this beer.
The drinkability is middle of the road. While its got a great mouth feel, its bitter like any IPA would be.Thought this is not a bad beer at all, in fact if you like IPA's but want some thing new try this beer and you will not be disappointed.

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.

Fairly bright orange pour. Limited white head, disappears quickly. Aroma not overpowering with hops, some malt, must and citrus/pear. Malt and citrus fruit is present with nice balance to the piney hops. A little smokeyness to the bitter finish. Does not linger too much either. Nothing overpowering and quite drinkable, yet not outstanding in any way. The suble burnt/smoke is a nice quality. Worth trying.

Pours clear amber with a large, lasting head.
Nose shows loads of piney resin, sweet caramel and cookie dough-like malt.
Similar flavours, pine, sweet clean malt. Finishes with a sharp pronounced bitterness.
Nice syrupy body, carbonation could be a lot higher though.

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.

, orange tinted honey colored amber being presented in front of me. Very hazy, with the cloudiness no doubt due to the unfiltered nature of it. A nice white head of foam, perhaps two fingers high then came over the top and settled down gradually to just a thin film of lace. Very nice appearance I would have to say. Some decent carbonation could be seen trickling up from the bottom and a good amount of side glass lace was involved as well.

The aroma was pleasant, not as strong as I would have liked, but still pretty decent. There was a nice floral hoppiness, somewhat muted hints of orange and lemongrass with a touch of pine. Decent malt base was apparent as the aroma of bread came through nicely. The flavor followed much of the same, owing that nice light floral hoppiness, but never having enough of it to really push it all the way forward. Nice little bite of bitter on the back of the tongue, and a slightly fruit finish, with apples coming through very clearly, especially in the aftertaste. The Mouthfeel was a little thin, maybe a touch watery, but had more then decent carbonation.

Got this one in a trade with stoutfiend27...Thanks Stephen!

A: No head to speak of, but the color is a beautiful crisp copper...any darker and this would look like a DIPA. Despite the lack of head, there is a surprisingly full laced pattern.

S: Sweet smell of caramel malts come through in a big way. There are also some earthy and citrusy hops with a decent amount of hop bitterness that pushes the initial caramel malt character away.

T: Sticky and bitter citrusy hops with some lighter earthy notes take control of the palate early. There is a lot of alcohol in this for an IPA, but none of it is noticeable in any way. The malt backbone is almost DIPA-like in the depth of its caramel flavor.

M/D: Surprisingly smooth, as the carbonation is low (expected after the lack of head). The feel is sticky and resinous, as the beer stays with you after the swallow. The hop character was good and fully. Very enjoyable overall.

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.

22.4 oz bottle at refrigerator temperature poured into a snifter. Bottle reads: "Batch 012, Best Before 08/16/10."

A - Burnt siena brown body with a foamy cream-colored head that backs down to splotches along the edges.

S - Floral, fruity, and spicy. The fruit character is stone fruit all the way - peach and apricot. The sweet malt profile reminds me of layered, complex heather honey. Quaffable and unique - altogether a very accessible and enjoyable nose.

T - A touch of bitterness from the hops, but by and large the hop character manifests itself as fruity and floral. I find the flavor profile to be very balanced and well-layered - everything just sits well together. Alongside the mildly bitter finish, I am again reminded of the richness and complexity of a darker heather honey.

M - The carbonation in this brew is pretty spot-on. Just enough to lift the heaviness of the malt character off of the palate, leaving behind the more subtle and understated flavor notes.

D - I thoroughly enjoy this brew. It's a refreshing change of pace from well-hopped and well-malted beers that have no appreciation for subtlety. On a relatively unrelated note, I have no idea why this brew is called "Chaos Theory." The pseudo-didactic description of chaos theory on the bottle does little to illuminate why the folks at BrewDog have named this beer Chaos Theory. At any rate, do yourself a favor and find this brew, along with some Cabot Clothbound Cheddar, some good butter, and a freshly-baked loaf of white bread, and make a grilled cheese to eat alongside this delicious brew. I'm fairly certain that will be a meal that you will not regret.
