Brewed by:
Stone Brewing
California, United States

Style: American Double / Imperial IPA

Alcohol by volume (ABV): 8.20%

Availability: Limited (brewed once)

Notes / Commercial Description:
First Release: February 2014
India pale ales harness the inherent flavor characteristics of hops to bring forward familiar flavors of pine, resin, spice, and citrus. In some cases, those botanicals are so potent, they exactly mirror specific edibles. Such is the case with Centennial hops, which hail from the Great Northwest and come across on the palate like a mouthful of citrus fruit. That sensation is amplified with this, the first beer introduced via the Stochasticity Project–a double IPA brewed with Centennial, Chinook and Magnum hops as well as an immense dosing of fresh grapefruit peel. The result is over-the-top bittersweet grapefruit intensity that is at once refreshing and bracing in its citrusy bitterness.

look: 4 | smell: 4 | taste: 4.5 | feel: 4.5 | overall: 4.5

Serving type: Bomber poured into pint glass.

Appearance: Golden, exceptionally clear with a white head that leaves a nice lace on the glass.

Smell: Bitter hops and, of course, grapefruit. Agitating the beer partway through unleashes another dose. Smells great.

Taste: Bitter hops and grapefruit notes with a touch of sweetness. Pine and citrus. The taste is fresh and clean with moderate carbonation. Pleasantly bitter on the back end (if you're into that kind of thing).

Overall: If you're a fan of a slightly more bitter ipa with great flavor, I recommend this beer. If you like sweet dipas, you may want to steer clear. This beer has a taste that is very "Stone," I'll admit to being a fan of most of their ipas. I wasn't surprised or disappointed by this brew, it's about what I expected... Then again, I have high expectations for nearly anything that Stone puts out.

22oz bottle I picked up in Ft. Collins because it was a couple bucks cheaper than it is in Denver, weird. Orange color, great head, this is a nice looking IPA. Aroma was mostly citrus with a hint of grapefruit, I couldn't tell if that was the peel or the hops. The flavor was very hoppy, citrus, and then a distinct grapefruit flavor that I knew was the peel. There was also a nicest backbone to this even though it was pretty much a west coast IPA. I also felt like thisight have still been a great IPA if they had left the grapefruit out. Overall this was a nice IPA.

Appearance- Pours up a whole bunch of head which looks to have good retention as well. The head is a pure, cotton white while the body is a dull, pale amber which appears as a golden pale amber when held up to the light. Considerable lacing that has some bands of sheeting.

Nose- Much more mellow than I expected this fresh DIPA to be. I assumed that it would be a hop bomb (it still may be) but all the notes of the nose are subdued. Mostly citrus- orange, lemon, and grapefruit. A touch of peach, maybe cherry. A slight bit of honey. Swirling shows mild peaches, mild mustiness, and grapefruit. Some caramel and hints of spice as well. Subtle but promising.

Taste- First note is caramel? Which is a little burnt at that? It then moves into citrus, some grapefruit (also, orange and lemon) but not nearly as strong as you would expect. Slight bitterness. Some warming spice on the finish. So far, this is continuing to not be the hop bomb that I thought it was going to be. Some peach, a touch of cherry. More caramel than I would have expected. Some matchstick but grapefruit is the dominant note here. Some pine and resin but they are pretty much buried by the grapefruit bitterness. Good beer and I have to give the brewers props for doing what they set out to do. It's never abrasive but there is always grapefruit on the palate. I wish there were more complexity. I like grapefruit but I like it better as a component rather that the defining characteristic. Still, a good beer anyway you look at it.

Mouthfeel- Between light and medium bodied with light juiciness and light carbonation. I hadn't noticed it until now but this is one of the best aspects of this beer. It really mellows out the flavor profile.

Drinkability- Starts off with big grapefruit which settles down very quickly and makes this a pretty mellow and very accessible brew. No sign of the 8.2% and worthy of the standard 6-7 bucks a bomber price for Stone beers. Probably wouldn't buy this again but you know I will be buying the next Stone or Stonish specialty bomber.

Overall- Solid beer which hints a being a really good beer. Somewhat simplistic but the grapefruit lovers should really appreciate it. Definitely worth a try.

Bottled 1-23-14

a: Slightly hazed golden copper color; poured with frothy cap that faded fairly quickly.

s: Truth in advertising, this is bursting with grapefruit juice aromas with some pith. Light sugar cookie and a trace of heat.

t: Grapefruit bomb for sure, I'm liking it. More juicy than pithy with some other citrus elements. Faint sweetness, mostly citric but some sugar cookie as well. Almost pure fruit juice in the finish with some aspirin bitterness. Almost too much grapefruit. Almost.

m: Moderate carbonation and just a bit watery.

o: You'd better like grapefruit. I enjoyed this but I'm bit in a hurry for another.

Bottled on 1/23/14 nice and fresh.

A- Golden amber and clear. A light fluffy two finger head quickly dissipates to leave a nice cap that leaves considerable lacing.

S- Powerful citrus aromas pour out of the glass. Lemon, lime, grapefruit and tangerine. Sweet fruity and crisp. I've heard about this brew and I can't wait to try it so here goes.

T- The ravenous citrus in the nose is slightly tamed with a pale dry malt bill that blends together nicely to create a harmonious balance. Getting a touch of pine somewhere in the middle. A mild spice and alcohol heat accompany a bitter lingering aftertaste.

M- Medium bodied brew that is a bit waxy. Dry finish.

O- All in all this is a solid DIPA. I personally love a hop forward beer that focuses on the citrus-grapefruit flavor and this one is right on. I'm surprised to find the malt backbone as prominent as it is but it doesn't detract, only balances out the flavors. Stone Brewing does a stellar job on most of their brews and this one is no exception.
