3/5  rDev -20.4%
look: 3.25 | smell: 2.75 | taste: 2.75 | feel: 4 | overall: 3.25

Cloudy golden orange colour with a smooth, off-white head. Good head retention and lacing.

Very light hop aroma. Some acetaldehyde. Lightly grainy. Not good.

Slightly grainy malt. Crisp, clear bitterness. Light tropical hop character. Disappointing and really quite poor for a Pale Ale yet alone an IPA.

Medium-light body with moderately-high carbonation. Fine.

Not a good IPA. I was really looking forward to this but the lack of punchy hop character really lets it down.

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

IPA single hopped with Nelson Sauvin (NZ) 7.1% ABV on tap in Edinburgh brewpub.
A- caramel nut colour, good clarity, really solid lacing and film, strong carbonation.

S- aged lemon, leafy, tropical mangoes, some caramel roasty malt, great balance.

T- hoppy, fruity coffee, tropical pineapple sweetness, aftertaste is dry, slightly herbal, pine note, nice complexity.

M- nice dry finish, moderate soft carbonation, slick mouthfeel but a decent balance, oily hopiness, really drinkable.

Overall, a bit hop heavy but a really nice showcasing IPA, could be more balanced but really good. Nice delicious flavour, with enough malt to hold it together.

3.78/5  rDev +0.3%
look: 3.5 | smell: 3.5 | taste: 4 | feel: 4 | overall: 3.5

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.

3.3/5  rDev -12.5%
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.

A clear amber brew, an off-white head leaving good lacing, some curtains.

The smell is fruity, red apples, peaches, grass.

Starting sweet, sugar coated bread, dried apples and peaches, a grassy bitterness.

Medium carbonation, foamy bubbles, a long dry finish.

Very sweet and fruity, and bitter in a good balance.

3.25/5  rDev -13.8%
look: 5 | smell: 3.5 | taste: 3 | feel: 3.5 | overall: 3

A: Pours clear copper with a large off-white thick and creamy head that settles into kick-ass lacings.

S: Caramell malt, only somewhat sweet together with lots of floral hops, more American than English actually. Citric and a bit piney. Grassy.

T: the caramell malt is a bit sweet, the hops are dominated by the American-style citric and piney vibe. There is a healthy dose of bitter hops as well. Honey and grass in the back.

M: The aftertaste is problably way better than the taste, ling bittermand balanced with sweetness. Body is medium while carbonation is medium but smooth.

O: Very nice IPA, but this is American, not English. The ratings would be higher if I was rewieving an American IPA.

3.05/5  rDev -19.1%
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.

3.38/5  rDev -10.3%
look: 3 | smell: 3 | taste: 3.5 | feel: 3.5 | overall: 3.5

A: Pours a copper colored fairly clear liquid into the glass. The three finger high head is foamy with fairly big bubbles. The head stays intact for a while before it slowly runs down leaving a ring of lacing at the top of the glass.

S: Smells like autumn leaves, grass and blackberries. Delicate hints of pine and floral hops. Grapefruit.

T: Tastes caramel malts, some sweet tones of honey, red berries (strawberries) with a long and bitter after taste. Peppery finish of alcohol.

M: Medium body with medium to strong carbonation that tickles the tongue.

O: Not a bad IPA at all, but not that special either.

3.55/5  rDev -5.8%
look: 4.5 | smell: 3.5 | taste: 3.5 | feel: 3.5 | overall: 3.5

Sampled at Brewdog Glasgow on-tap.

Clear amber with a half inch foamy white head that has good retention.

Mix of pine like hops and a mild, tropical fruit aroma that is coupled with a malty smell. It's rather sweet and pleasant, just unusual at the same time with a little bit of wheat and some floral notes.

More bitter than the nose with the tropical fruit & pine flavours (not as strong as in nose) being followed up by a strong bitter presence & some sweet malts.

Light side of medium body. Smooth, dry & was rounded of by a quite bitter finish.

A nice, highly drinkable beer that I would compare to Punk IPA but with less hops & a little more bitter in the finish. Nice but not the best from the brewery.

4.28/5  rDev +13.5%
look: 4 | smell: 4.5 | taste: 4.5 | feel: 3.5 | overall: 4

, 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.

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

Poured into an imperial pint glass, it's a hazy deep orange color with a finger or so of white head that laces quite nicely.

The aroma is malty and warm more like a barleywine than an IPA at first. The hops are definitely there but it has a really nice balance to it.

The taste is still pretty hoppy with bitter grapefruit flavors and then a nice malt kick. It's not as balanced but I really like it a lot.

A really nice IPA / barleywine hybrid style beer if you ask me.

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

Poured this beer into a pint glass, revealing a reddish amber brew, with a short head. Very little hop aroma for the nose, well balanced malt flavor on the tongue, caramel, low carbonation. Moderate bitterness, little lacing, all in all, an English style IPA if I've ever had one. A little disappointed that this isn't a bigger beer, with a little more of just about everything.

4.08/5  rDev +8.2%
look: 4.5 | smell: 4 | taste: 4 | feel: 4.5 | overall: 4

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.

Best by 8/10... I just bought this recently in the store too so either the store held it on the shelf, or distributor...

Pours a light fizzy head, rosy reddish orange maroon apricot color, very hazy.

Nose loaded with fruits, apricot, apple, raisin, fig, dried fruits, Belgian yeast, very light hop character.

Taste starts with a slight bitter apple seed, fruit, fig, raisin, apricot, bitter rind taste, bitter hop character as well, chewy hops, little yeast, Belgian yeast fruits, long bitter finish, light fruits, chewy spicy hops, light yeast.

Mouth is med bodied, decent carb.

Overall decent, interesting fruits, bitterness, some light hop flavors, probably better fresh.

Single-hop IPA. Not nearly as robust or complex as Punk or Hardcore, this has all the family resemblances of the BrewDog IPA family: lovely head and robust cloudy straw color, robust hop smell, deep, rich taste. But the single hop leave it a bit one-dimensional. A really great beer; just not as good as the last Punk I had.

This poured out as a copper color with some minimal head. There wasn't any lacing on this one at all. The smell was earthy and really didn't have much of a hop aroma to me at all. The taste was the same way, it was mostly on the malt side and not even close to having enough of a hop bitterness in my opinion. The mouthfeel was kind of on the flat side. Overall this beer was really disappointing. Very surprised at how unimpressive this was coming from a brewery who usually makes a killer IPA.

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.

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.

A - Pours a cloudy light copper into my tulip glass with just about a finger of head that lingers a little and leaves some splotchy lacing.

S - Sweet caramel malts and a mild hop presence. Grapefruit, apple and pear.

T - Sweet caramel and bitter hops. Pine/resin like hop quality with apple and pear like notes to it.

M - Perhaps because it's a few months past expiration but it is under-carbonated and a little thin.

D - This was a good beer, nothing I was too excited about, would try it again if I got it fresh.

Pours clear amber with a large, lasting head.

Similar flavours, pine, sweet clean malt. Finishes with a sharp pronounced bitterness.
Nice syrupy body, carbonation could be a lot higher though.

A- pours amber, with about an inch of fluffy off-white head. subsides pretty slowly, leaving some lacing.

S- little yeasty, with some peppery hops. not too much going on.

T- quite malty to begin with, followed by some peppery, slightly piney hop, little bit herbal, but it is quite nice. finish is pretty bitter, but not over the top.

M- prickly carbonation, can feel the bitterness at the back of the mouth. mid length on the finish.

D- pretty easy to drink this one. i could have a couple very easily.

This brew pours a murky light apricot hue with decent carbonation that leaves behind a creamy two finger head that stays and leaves some nice lacing,the aroma is a combination of toffee/caramel malts,fresh green apples and piney hops and lots of them,it has a medium bodied mouthfeel which is a tinge stickyish and leaves tastes of passionfruit,peaches,lychee,toffee and finishes with a bittersweet tinge thats more bitter than sweet,overall a nice drop without being a standout and i know this brewery is capable of way more.
