On tap at rock bottom brewery. Only $3 a pint during HH.

Great golden orange color with a pure white 1 finger chunky head that hung around for most of the beer. Really nice sticky lacing left on the glass. Fantastic smell of lemon and grapefruit hits you quickly. Very, very nice aroma. Great tasting as well and the hops dominate in that arena. Lots of lemon and grapefruit again with a hint of orange and malt sweetness in there. Mouthfeel is good and the beer was very cold and had a lot of carbonation. I love a cold beer but I think this one could be served just a tad warmer. Excellent drinkability and highly recommended. I see a growler in my future for the weekend.

Brian really makes some good beers.

First had: on tap at Rock Bottom, King of Prussia, PA

A tasty IPA hopped with Simcoe. Unfiltered and hazy to the point of being opaque, golden-straw color with a foamy white head that left thick lacing on the glass. Pine and pineapple in the aroma, light hints of biscuity malts. Nice display of Simcoe in the taste, pine, citrus, pineapple, crisp and clean, with a solid but subdued biscuity malt base. RB may be a chain, but they still can make some good brews. Medium body, soft carbonation, and much better than their typical house IPA.

What a pleasant surprise! Brian's been doing an impressive job, and this one's no exception.

It's a clear, deep amber-gold beneath a creamy head of white. The aroma clearly displays the pineapple/pine/resinous Simcoe hops, and the flavor delivers them even more clearly. A sweetish, straightforward golden malt acts like a big rubber ball for the hops to leap around on. Nice! The 7.2% abv and 71 IBU's combine to balance it, and along with the carbonation it gives a bit of zest to the tongue. Well worth seeking out.

Grabbed a growler at the bar on 1-14-11. Reviewed from notes.

Chalkboard above bar notes a birthdate of 1-6-11.

Liquid is a light orange in color with moderate carbonation and very little foam or lacing. This looks much cleaner than expected and the haze is very mild for an unfiltered IPA.

Simcoe hopping is obvious due to the pungent pine aroma. It smells sweet and fresh, which is to be expected from an 8-day old beer.

Hop flavor is strong, packing both dry, resiny bursts and warm, citrus sweetness. Flavor is earthy and even has the slightest tobacco smokiness, which seeps in after swishing the liquid around in your mouth. Dry conclusion lingers and carries a shade more maltiness than expected.

The layering of flavors is the key here and this beer manages to walk the line between hop burn and fruity sweetness well. This is one of the brewery's more balanced affairs.

Even though it gets sweeter as it warms, this is probably the best hoppy beer the King of Prussia Rock Bottom brews. It manages to be basic enough to lure in novice beer drinkers and hoppy enough to keep the veterans happy.

Poured from growler into a standard pint glass.

Appearance: Pours a golden-orange with about a finger of foam on top that settles quickly.

Smell: Whoa hops. Nice hoppy aroma with some citrus notes. One the best smelling beers I've ever had.

Taste: Hoppy bitterness, grapefruit and malt on the backside. Very nice flavor.

Mouthfeel: Smooth, crisp and medium bodied.

Drinkability: I had a pint of this at Rock Bottom and was completely blown away. I am going to be filling my growler as many times as possible with this beer while I can. Very good beer.

Tapped this on wednesday. I had it thursday. Poured into a pint glass.

Appearance: 1 finger foamy white head on top of an orange colored brew. Considerable lacing down every side of the glass.

Smell: Simcoe hops. Very noticeable aroma's of grapefruit and pine. Very mild malt backbone lending a hint of sweetness.

Taste: Wonderful. An abundance of pine and a very fresh grapefruit flavor. Malt sweetness is in there to lend some balance, but this is quite a hop forward beer. Some citrus flavor mixed in there as well.

Mouthfeel: Medium bodied beer with a good bitterness to it in the finish. A prickling carbonation hits your tongue about half way through as well.

Drinkability: Brian makes some of the most drinkable IPAs I've ever had. This is no exception. I drank these all night until I was finally ready to go home.

Another top notch IPA from a gem of a brewpub in my hometown. What a treat.

Growler share thanks to Ffejherb.

A-Slightly hazy, golden copper with a creamy off-white head that held on strong and left decent lace.

S-Strong spicy citrus and pine hops with a sweet biscuit malt support

T-Juicy citrus and pine hops meld with a nice backing sweet biscuit malt backbone. A mild caramel sweetness and bit of spice sneaks in the finish.

M-Medium body and quite smooth. Nice lingering spicy hop bitterness.

D-Good stuff....heck about as enjoyable as the much hyped Grit 16 we also drank! A damn solid and enjoyable brew.

Poured via growler procured from the KP brewpub on 1/23/09. Shared with brewslut, Deuane, SierraGS and dashirey (and Jill).

A - Poured a cloudy, unfiltered golden body with mild carbonation and one-finger creamy off-white head that retained very well and left a bit of lace around the glass.

S - Reeks of spicy, citrusy and piney hops with a waft of bready malt and some sweet caramel, as well as a bit of alcohol in the back. I definitely detect Simcoe hops in this one. Very nice nose overall.

T - Bold hop presence up front featuring citrus and pine notes with a mild alcohol sting in the middle, followed by an ample bready and sweet caramel malt backbone. Finishes with a bit of graininess and more spicy hops.

M - Medium body with a syrupy texture and soft carbonation. Sub Zero ironically elicits a bit of warm alcohol heat, but just a bit. Finishes with an assertive hop bite on the palate.

D - Very flavorable IPA with good malt balance. While it has a stronger alcohol presence than I was anticipating, it didn't really detract from my enjoyment. I've been wanting to try this for a while, and it didn't disappoint.

A: Very pale honey color, highly turbid. Fluffy pure white head.

S: Wonderfully hoppy. Like getting lost in an Oregon pine forest and the wandering onto a citrus plantation.

T: Again, dominantly hoppy. Crisp pine profile that leads into a slightly acidic citric character. Light and fleeting malts. At the end there's a piquant lingering citric bitterness.

M: Medium bodied and crisp.

D: One of the better American IPA's I think I've had. The Simcoe hops have a fantastic profile.

Served in a Mug Club mug from tap at the RB bar.

A: A lighter amber orange color with a creamy white head and thick glass lacing. Looks great.

S: Hops? Yes, hops baby! All simcoe here with heavy smells of grapefruit and pine. Very little if any malt smell.

T: Wow, hophead dream. Massive amount of pine, more than the nose indicates coupled with a fresh grapefruit flavor. No doubt classic simcoe hops flavors. A mild malt sweetness lies underneath but this is where the beer differs from say a Doulbe Simcoe. This is actually hoppier with the lower ABV and has much less malt flavors. I love it! Finish is hops bitterness that lingers in the mouth.

M: A nice coating mouthfeel that is crisp but lingering. No alchohol feel at all, very nice.

D: High, end it right there.

Overall what a fantastic beer. Rock Bottom has yet to disappoint me with any of their IPAs, they really are doing some nice work over there. I suggest you all try it. Cheers, I think I might go back and get a growler I loved it that much.

I had this at Rock Bottom Restaurant and Brewery in King of Prussia, Pa.
Appearance: A light amber colored body that was pretty translucent. A huge off white fluffy head with great retention and even better lacing.
Smell: Very citrusy, mainly grapefruit.
Taste: Not too bitter, but again strong backbone of citrus (it was brewed using Simcoe), mainly grapefruit. A bit wattery.
Mouthfeel: Pretty darn rigid.
Drinkability: Very good.
Don't drink and review.

On tap at the brewpub.

Pours a clear golden amber color with a finger's width of brite-white head that retained well and left some nice, sticky lace down the sides of the glass. The aroma is a little subdued, consisting of mostly piney hops and citrus.

The taste begins with ole' piney harsh bite of Simcoe hops and citrus up front that lasts well the through the sip. There is some slight caramel sweetness that acts as a backbone but some more is definitely needed to help temper those hops. The mouthfeel is medium bodied with some prickly carbonation that gives it a nice, full feel.

Overall, this wasn't a half bad IPA. While I appreciate a big dose of hops like the next guy, this one could have definitely used a little more balance. It's definitely something you can deal with though and it still remains a very drinkable brew.

Pours a slightly hazy yellow/amber with a pinky's width of creamy off-white head, good lacing. Smells of grapefruit, floral hops, and some sweet caramel. Taste is big in grapefruit and grass with a nice malt backbone, though a little weak. A dry piney finish sticks to the tongue. Medium in body, smooth and creamy, and good carbonation. A good IPA using only Simcoe hops, but a little unbalanced.

This beer I had the day it was tapped at Rock Bottom. I'd heard it was an all-simcoe IPA. I was expecting it to be like Sly Fox's super grapefruity version so I must state that it is different from that, but not bad. The taste and smell at first seem to be overladen with banana. It appeared more like a belgian blonde/strong ale in color and in the first few sips. After discussing with others sitting around me, it was not thought to be banana as the overpowering note, but more peach/apricot/melon.

Ahh yes, as I worked my way down the pint, it became apparent that the fruit notes are complex and subtle, as the simcoe hops in this beer have chosen to take that route, versus the more bracing route I was used to (brisk grapefruit burst), like they do in Sly Fox's version. This beer challenged my brain as my palate tried to sort out what's all going on in there. Overall I can't remember what the malt character were like, but I don't recall it being unbalanced. Nice job to the brewer--more like these and you will soon be a superstar around here.

Served as a cloudy medium amber beer with moderate white puffy head.
Smell is loaded with hops (piney, grassy, citrusy) and very enjoyable.
Taste is also dominated by hops (its brewed exclusively with Simcoe hops), yet is nicely balanced my some sweetish malt.
Finish show more hops, leaving an intense dry bitterness.
This was an excellent beer. This would be something they show brew at least seasonally.
