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.

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.

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.

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.

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.

, 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.

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.

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.

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.
