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.

Shared with a buddy at belmont station.

A - Poured copper gold with a 2 fingered off white head. Dissipated moderately slow and left nice lacing.

S - Honey, caramel, light bittering hops, and breadiness.

T - Honey, caramel, bittering hops, bread, and light nectar.

M - Moderate-bodied with an off-kilter balance. Hops and malts did not mesh well together. Lightly dry, but smooth.

D - An interesting beer. An American beer brewed by brits. Would be wlling to try again, and alcohol well-hidden.

3.89/5  rDev +3.7%
look: 3 | smell: 4 | taste: 4 | feel: 3.5 | overall: 4

A - A cloudy light brown in colour, with a small but thick head, that showed good retention throughout the pint.

S - Noticeable hops, with some very fruity notes.

T - There is a strong fruity base to this IPA, a slight orange tang, with what tastes like melon or grapefruit. A strong bitter aftertaste of hops, that is long lasting. The is no real sign of the whacking great alcohol content in the taste.

M - Quite thin in the palette, with a mildly watery body.

D - A nice pint overall. Doesn't show signs of the high ABV, so be careful when knocking this back, as it is very easy going when drinking. I'm a big fan of IPAs, and this is the first American style one I have had, and I will definitely be seeking out more beers in this style.

A very nice, powerful IPA. Sturdy, almost heavy, but not in a bad way. This is a pretty substantial beer. Big hops, nicely bitter, with hints of maybe vanilla or something. There's some nice depth here. Overall, very good, but not quite great. Definitely would have again if the opportunity arose.

Pours a medium brown color with a nice head that fades to leave lacing in my glass.

Aroma is full of sweet malt and floral hops that are nearly hidden in the nose.

Taste is full of light, floral hop bitterness and sweet malt underneath. Bitterness isn't too much nor too little.

Mouthfeel is full of lingering hop bitterness and malt like a typical IPA. Feels British in character.

Let's see, easy to drink and feels like a British IPA that is a bit stronger than usual in flavor. American hops and British malts more like it. Something like that. I'm obviously lacking in geography. Regardless, try it. It's not their best effort though.

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.

Pours a dark amber bordering on red, although again a rather minimal head.

As would be expected from an IPA, the nose was full of citrus, in fact it was very pungent, with a mix of Seville orange marmalade and bittersweet pink grapefruit. The contrast between bitter and sweet was to be a constant theme in the beer, the first taste being very bitter, and something of a shock if the truth be told, but subsequently it mellows out to reveal its jellied undertones.

As you would expect from this style it is very hoppy and the aftertaste reminded me of drinking an excellent single malt with a nice warming afterglow. The final few mouthfuls were syrupy sweet in a way that reinforced the jelly, an excellent beer overall.

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.

Picked this up today @ Marty's in Newtonville. Batch 012 with BBD 8/16/2010. 500 ml into Portsmouth snifter. I would call this an American IPA rather than an English IPA because 1) the BBD is in American rather than European format (mm/dd/yy; not the real reason) and 2) the hop profile and forwardness with a bit of malt rather than a balanced or malt-forward profile fits the American IPA mold much better.

Man, I wish the carbonation on this would have a little more staying power. It's listed as a "copper IPA" and it definitely is. The eggshell, full-finger head looks solid...for about 5 seconds...and then it goes quickly, leaving those thin bubbly wisps. Not a lot of lacing on this one, but I'm struck by the clarity of it all.

The website says "insane hops." Well, they should move up the BBD then 'cause no way in hell these hops make it to 2010. But I really don't give a rat's ass, 'cause I'm checking this deal out now, and insane indeed. The pure grapefruit pulp reminds me of the Sculpin I had the other day. A slight hint of caramel and boozy sweetness balances this out very nicely on the nose. A pleasant surprise.

I do get the graprefruit on the taste but it is much more rind than pulp. The creamy caramel malt texture is still there and this is definitely a hop bomb. It works well and shows a fair amount of synergy; only beef is that the rind profile of the hops takes away from the clarity on the nose. Maybe they take a portion of their FWH or maybe their 60 minute and jack it down to 20 and 5 to show up a little more on the nose and less on the bittering. Still, this is quite enjoyable.

There is still the rind smashing the palate into oblivion. This shows a little disjoint with the caramel malt (crystal) and a little bit of slate and earthiness. Good and enjoyable but maybe not as tightly constructed as the top range of well-oiled (higher ABV) IPAs.

It's an enjoyable IPA with good synergy. Just enough malt to sit on the other side of the seeaw with these crazy-$#!+ "C" hops. Slight dryness keeps it clean. Finish has a bit of earth but not a huge amount. This is an enjoyable capper to have every couple of weeks - it smells like a rotating release but may be a one-shot deal...sort of like the "longshot" BBC contest. This is a prototype rather than a user recipe so let's hope it makes its way around each year or more frequently. Nicely done.
