3.5/5  rDev -11.8%
look: 3.5 | smell: 3.5 | taste: 3.5 | feel: 3.5 | overall: 3.5

22 oz bottle. Pours clear golden orange with a medium creamy white head that retains well and laces the glass.

The aroma is sugary bready malts and tropical fruit / grapefruit.

The flavor is a little sweet fruity bready malt followed by a pretty big resiny bitterness. The mouthfeel is medium bodied with light carbonation.

Overall, a nice IPA, but not as good as I thought it sounded.

Bottle share at Proof done side-by-side with Proof's Guru IPA blended with Apollo aged on grapefruit. Pale straw in color with very little head. Big grapefruit and orange citrus with some tropical fruit in the aroma. Taste is spicy/citrus combo with a fair malt backbone. High carbonation (despite little head) and medium body. I enjoyed the Proof considerably more.

22oz brown bomber with a freshness date.

Stunningly tight and sticky lacing on top of this hazed out pale amber brew. Big bag of smashed grapefruits rush the nostrils, hints of alcohol and hops within. My palate is simply being abused by the onslaught of grapefruit and hops, the alcohol is clean and quite warming. Some light bready tones underneath but the finish is just more lingering grapefruit and hops.

Slam? This is a Smackdown, thanks Stone for this one and keeping things fun.

look: 3.5 | smell: 3.75 | taste: 4.75 | feel: 4.75 | overall: 4.75

Appearance: Rich, thick. It's like seeing an old enemy you know you have dealt with in the past, seemingly overcome, but back for vengeance...

Smell: Sweet. Too sweet... is this my baby brother's Juicy Juice?

Taste: the taste is abrupt, sweet, and forward: as awe-inspiring as its Mouthfeel:

As powerful and spontaneous as tens of 500 gram repeaters exploding all at once... the feeling of looking up and being humbled by grids of color, spiraling and swirling simultaneously, overtaking all senses and reinventing the processing procedure of all you know.

Overall::: An IPA that acts not in pretense, but divine truth in its intensions and outcome.

Drank up.

22oz bottle at fridge temp poured into a tulip. Bottled on 1/21/14 (~1 1/2 months old)

Pours out a very clear bright light orange color, holds a nice 1 finger or so of white to slightly off white head for the first half of the glass or so. All in all good head retention and a pretty good amount of lace stays on the glass.

Initially the aroma was big grapefruit and pine but as it warms it turns into dank, resinous, bordering on vegetal hop aroma. Lots of fresh grapefruit rind, lots of raw pellet hop aromas.

Grapefruit blends in so nicely, you get a grapefruit juice, slight orange juice flavor, grapefruit rind, huge resinous quality. Citrus and pine from the hops is there a bit. Slight hints of a bready malt bring a nice backbone to the beer. Hop oil, resin!

Sticky, resiny hop bitterness lingers on the palate in a big way, more so than most IPAs. This is where it's really reminiscent of ruination.

It's been awhile since I've had ruination, but this is top notch. The grapefruit is apparent and works with the hops well. I'd buy again.

look: 4.5 | smell: 4 | taste: 3.5 | feel: 3.5 | overall: 3.75

Bottle poured into a tulip

A - A pretty orange color with a one finger head. Crystal clear but very active carbonation

S - Grapefruit with a touch of sweet malt in the background. A little muted.

T - A full grapefruit assault on your palate. Super hoppy.

M - Palate wrecker for sure. Very dry finish, a touch oily, and very bitter.

O - Very harsh on the finish and excessively bitter. If it was toned down a bit, it would be more drinkable.

look: 4 | smell: 4.5 | taste: 4.5 | feel: 4.25 | overall: 4.25

Poured from a 22 oz. bottle into a Surly Darkness chalice. Bottled on 01/29/14.

Appearance: Pours a bright and clear golden orange with a moderate amount of bubbles. Solid two fingers of white head with decent retention. Leaves a good amount of creamy lacing around the glass.

Smell: A ripe, juicy, and very hop forward West Coast IPA aroma with big hints of grapefruit and citrus. Upfront scent of juicy citrus hops with big hints of grapefruit, orange peel, mango, pineapple, lemon, tangerine, and apricot. Dank smell of pine resin and some earthy hints of grass. Backing presence of pale malt with hints of grains, straw, and yeast. A very ripe and nicely bitter hoppy aroma.

Taste: Like it smells, a very juicy, ripe, and bitter hop forward taste with big notes of grapefruit and other citrus. Upfront juicy taste of citrus hops with notes of grapefruit, mango, orange peel, lemon, pineapple, tangerine, and apricot. Dank and spicy taste of pine resin and some earthy notes of grassy hops. Pale malt with some notes of grains, straw, cracker, and yeast. Nicely bitter and drying. Very good taste.

Mouthfeel: Full bodied with a moderate amount of carbonation. Very juicy, oily, and drying. Pretty smooth with a well hidden alcohol presence.

Overall: Another good IPA from Stone. The added grapefruit adds a nice kick to an already juicy taste.

I though this was a really nice grapefruit forward ipa. Everything I could ask for in an ipa with a touch of grapefruit. Better than Grapefruit Sculpin imo . . . Hope to see this beer on the shelves again someday.

Split a 22 oz bomber with wvsabbath, great hoppy IPA with a kick of grapefruit peel bitterness. Pours a copper hue with bright white cream head, it slowly fades into speckled even layers of lacing. Aromatics pungent grapefruit, citric herbal hop bombs. Flavor has hops all day, bittering in between the waves of hops includes the grapefruit pith/semi sweet malts married with those bitter hops and citrus oils. I'm a fan, and it's distinct that they didn't use the dry orange peels like some of the wheat/witbiers out there. Leaves the teeth lacquered with a pleasant level of bitterness especially if you're a hophead in the first place, hold on that's probably a requirement to truly appreciate this IPA infusion. Carbonation is dead on carries the resins/oils well across the palate, great stuff easy, too easy to drink. Overall keep looking for it until you get to try this.

look: 4.5 | smell: 4.75 | taste: 4 | feel: 4.5 | overall: 4.5

A: approaching a mosquito-stuck-in-Jurassic amber color.

S: Grapefruit, mango, pine, and sunshine.

T: Heavy grapefruit and hop bitterness gives way to some juicy citrus flavors and subtle tropical notes. Finish is dry bitter.

M: Juicy then dry.

O: Pretty solid. Not the best grapefruit IPA but a fair contender. Good flavor, great scent. The bitterness is a bit overdone as is Stone's style but it's at least fitting.

Happy St. Patrick's Day!

Pours a light golden orange with a finger of head. Pretty good lacing.

Grapefruit expectedly dominates the nose, but not completely. Drier resin and pine also shine through. Very slight hint of sweet malts to balance it a bit.

Pretty much as expected. Bitter grapefruit, citrusy/lemony hops, and some pine all the way. The peels must add a touch of sweetness as well that makes this really nice. The more I drink the more grapefruit I seem to get.

Medium body medium carbonation, aftertaste is strong with grapefruit and only increases.

Very good overall. It delivers on the grapefruit and the IBU's.

look: 4 | smell: 4.5 | taste: 4.75 | feel: 4.5 | overall: 4.5

22 ounce bomber with a bottling date of 1/30/2014 printing above the label, poured into my Beer Geek Nation tulip glass.

Appearance (4/5): Clear and copper colored. Tight bubbling and a bone white, two finger head of foam. Lots of lacing clings to the glass. What bumps the score up to 4 is the remarkably creamy and tightly bubbled head. This is as good as a clear/filtered IPA is going to look, at least in my book.

Smell (4.5/5) Incredibly grapefruit forward with a nice sweetness from the crackery malts. Some oniony dankness and spritely lemon-like freshness lurk behind the grapefruit. This smells so fresh. Wow!

Taste (4.75/5): Follows the nose brilliantly. Extremely bitter and piney in the beginning, then in the middle and finish you are just crushed with grapefruit rind-like bittersweetness. This is not a generic citric flavor--it's specifically grapefruit, as you'd expect with the adjunct in question. Crackery malt lends enough support to really make the hops shine. The beer truly delivers on the promise in its name. This is a grapefruit bomb.

Mouthfeel (4.5/5): Medium body, medium carbonation, and an extremely dry finish (very West Coast-style in profile). Juicy and smooth in the foretaste. This beer makes my mouth water, there's so much grapefruit and hops in this beer.

Overall (4.5/5): You guys know already–I think this is a great beer, though I'm not sure how much people who don't like grapefruit will enjoy it. But who the hell cares? Stone...ermmm...the Stochasticity Project makes uncompromising, aggressive beers. I can't wait to see what the next beer in this series will be.

Poured a cloudy golden color with a thin white head that dissipated quickly, but left nice lacing down the glass. A bit lighter in color than a lot of DIPAs, but overall not bad looking. Scents of citrus peel, overwhelmingly fresh grated grapefruit peel with lesser but still present aromas of pine resin,grassy hops, tropical fruit, and biscuit-like malt. A very good DIPA aroma with the grapefruit peel added being quite apparent. Very nice. Taste begins bitter with abundant flavors of fresh grapefruit peel, and also pine resin and herbal hops. There is a slight sweetness throughout and a hint of grainy malt on the finish. Bitterness, floral hops, grapefruit peel and pine resin carry throughout and into the aftertaste. Very nice, the grapefruit peel is certainly the main attraction here and it works quite well with the hops. Mouthfeel is medium bodied with moderate carbonation and a resinous and slightly juicy feel, quite to style for a DIPA. Overall this is an excellent DIPA. Using grapefruit peel as an ingredient really paid off and adds to the usual citrus flavors of the West Coast hops. If you can try this one, go for it.

A large, densely frothing and exceptionally creamy substance, very slightly yellow-tinted, forms as a thick, strong head that only slowly falls from two fingers and throws legs everywhere as it does. The beer itself shows some clarity in its sunshine-bright golden-orange depths.
There's certainly no shortage of hops here, and citrusy at that. The aroma doesn't quite showcase the full grapefruit effect that's displayed in the flavor, but it's absolutely got plenty going on. Citrus is, of course, the main event, with just enough support from caramel and bread, very nicely balanced. A bit of alcoholic warmth tingles the nostrils with a bit of orange peel and something herbal runs underneath; it's more of a kitchen herb than typical. While I'm not blown away by grapefruit as I almost expected, it does show its presence.
Then, BAM...the first bittersweet surge on the tongue is straight grapefruit juice. It's almost a blend of ruby red and the more bitter white-orange pulp. It's got rind, flesh, juice, all of it, complemented by just enough caramel and a hint of breads. Drying leaf and herb head into the otherwise juicy finish, hugely lingering.
The medium body supports a feel that's biting, bright and clean. The juiciness translates, as well as the bittering dryness and that of the herb and leaf. The finish is a smooth and long-lingering one continuing to balance the juice and the dryness.

Sort of waiting for this one mainly because of the idea with Grapefruit Slam. I know that hoppy bears do have that grapefruit aroma along with other citrus noses. And I have always appreciated the level of citrus in Sauvignon Blancs, especially any from New Zealand which have the biggest grapefruit nose of any wine, plus tastes like butting into a pink grapefruit.

The nose here was big, but really not much more than I have had with other big hopped bears. The initial taste was light and crisp , like any other real good hopp'd bear.
But I missed everything about the grapefruit here.

I liked this beer, but the name to me doesn't go along with the taste.

Had on tap at O'Niell's Pub in Albuquerque, New Mexico.

A- finger thick head, frothy, chewy and light khaki in color. Copper-colored liquid with slight carbonation visible. Certainly a clean-looking beer.

S- citrusy and floral with a sweet malt backbone

T- It has a definite grapefruit taste, particularly the taste of the peel. There's also some sweet malt, and citrusy and floral hops working in concert.

M- Sweet and malty initially, the bitter from both the hops and what I assume is the grapefruit which provides a sensation like biting into that fruit. The beer has a medium body with mild carbonation.

I like the citrusy characger of this beer, but I also feel that the grapefruit peel deal is a bit overbearing and doesn't quite appeal to me. If not for that aspect, this would be a shining example of a DIPA.

Translucent golden amber with a pithy colored white head. Onset lacing is prevalent and then all but gone towards the end.

A sleeper of an aroma with faint citrus and aromatic hop-like a scratch and sniff.

Bam! Time to wake up 'cause because Stoch has arrived. Prominent grapefruit rind is evident. Pipe resin and dried hop cone. This is every bit of 95 IBU.

This is deep to left field and refreshing. Semi-sweet malt and an earthy bitter aftertaste.

A very straight forward hopped up brew with substantial ABV. Very welcomed indeed! For those who love hops, you've just been saluted!

Clean clear orange beer, white medium sized head. Some waves of lace on the glass. Aroma is grapefruit of course, fresh and pulpy, over bread dough and crackery malts. Actually a pretty simple aroma. Bright and fruity, floral, a little spice, fresh and hoppy. Taste is dry, bitter, acidic, nice light malt profile with straight fresh hop cone flavor. Grapefruit pulp bitterness is in here for sure but not overwhelming which I thought might be the case. Very fruity and very centennial in hop flavor. Refreshing and hop forward. Mouthfeel is smooth first, then massively resiny and hop oily. Bitterly mouthwatering. Coming from Stone this is right where I expected it to be aside from my worries of too much grapefruit pulp bitterness.

Bottled on January 23, 2014.

Seved chilled into a shaped Sam Adam's glass.

Stochasticity Project Grapefruit Slam IPA (what a name!) is a slightly hazy pale copper color. The head is thick and slow to settles leaving some nice lacing behind.

Aroma is fresh and full of grapefruit citrus. Candied orange peal and homey also come through.

Flavor wise, it starts off with sweet citrus candy but quickly turns potently bitter. Tons of hops and lots of citrus obviously but perhaps not as grapefruity as some double IPAs that are so only because of the hop profile. The addition of grapefruit peel in this beer adds a lot of bitterness and a little flavor.

Mouthfeel is medium bodied and very bitter with just enough sweetness up front to give it some semblance of balance. Carbonation level is right on.

Overall a very interesting and enjoyable IPA. I look forward to what others beers come out of this project from Stone.

A - Straw colored with white head and chuncky lacing.
S- Citrus smell comes through well with grapefruit being the primary. Piney hops also prevelant.
T - Solid, well balanced IPA with nice sharp hops and the tart/sweet grapefruit tucking into your cheeks.
M - Standard single IPA feel. Nice and smooth.
O - Very enjoyable. I wish I had it a bit fresher...6 months since bottling.

Served in thick fishbowl a deep amber, with limited lace. Lovely.

Aroma is rich tropical fruit hoppiness. Yum.

Taste is delicious and over the top grapefruit. Bitterness is almost nonexistent. Sweet and citrus tastiness. Finish is slight bitterness but mostly delicious and aromatic tropical hops wonderment. Very drinkable, and a unique and refreshing take on an Imperial IPA. Alcohol content isn't readily apparent, either.

Absolutely loved this IPA, and will be looking for a bomber now.

22oz bottled on 1/2?/14. Slightly viscous, though super pale yellow pour, with a positively forming, though thin, white head. No surprise, there's a big citrus hop aroma coming off this one. Flavor-wise, also as expected, this is a bitter affront on the top of the palate. Citrus flavors, which after a while develop to reveal pure grapefruit taste, come across in the heavy dose of IBUs. I've obviously had more unbalanced double IPAs, but there's not a lot of malt to balance this out. Or rather, there is quite a bit of malt, but it doesn't contribute much, flavor wise.

I do give this beer serious points for the excellent label art & choice of name. Well done Stone.

look: 4.5 | smell: 4.25 | taste: 4 | feel: 3.5 | overall: 4

Huge ~4 finger pour in a large ale glass from a turbulent pour. Surprisingly dark coppery pour, settling to a golden straw color with orange highlights. Head is bright white and fluffy, which great retention and nice sticky lacing. Transparent and slightly bubbly.

Expected single IPA aroma, reminiscent of Mosaic, although apparently that's the Centennial and Magnum combo (I'm not very familiar with Magnum hops). Citrus and tropical fruit in equal measure, with some sweet dankness as well, floating on a biscuity maltiness. Slightly floral, with some honey. No significant grapefruit aroma.

Flavor dutifully follows the nose, with a balance of floral, tropical, citrus, dank, and pine hops that blends together in a way that makes it difficult to pick out the dominant flavors. Grapefruit peel is mostly present on the back-end, with a dry citrus finish, typical of older IPA hop profiles. Definitely a super bitter brew, impressively so (think Ruination), although mostly present on the back-end; the front and mid palate hoppiness is more of the hop juice variety.

Grapefruit acidity definitely builds up as you drink it, giving it a nice balance to the fruity hops.

Lively with a nice sting; juicy middle, with a semi-dry finish that lingers forever. A little sticky residue. Fairly drinkable.

This is a solid DIPA; I imagine this is how Enjoy By would be if they went for massive bitterness and astringency instead of fruity flavors. Worth trying, but I don't think I'm going to revisit it any time soon.

on-tap, pint at the Dray

Bright orange body - mostly clear, nice sudsy head. A hybrid IPA/DIPA - a little on the heavier end with a light booze sting. Grapefruit zest enhances the citrus hop profile - lots of hop resin, orange peel, lemon. A solid option - nothing real groundbreaking, just good.

on tap at greyhound in la, but sadly served in the puny 8 oz format. olden amber in color, the beer left white lacing. subtle down the sides of the glass. aroma is less enticing on the initial sniff as i would have hoped. some subtle citrus with grainy notes and grapefruit skin in the background. on the palate i get the grapefruit slam; more white than red grapefruit on this brew, plus bracing bitterness on the finish. cant taste the 8.2%, which is good and bad. pleasing and dry overall.
