3.78/5  rDev -5.7%
look: 3.75 | smell: 4 | taste: 3.75 | feel: 3.5 | overall: 3.75

Bottled 1/23/14.

Pours a clear honey orange with a foamy orange-tan head that settles to a partial film on top of the beer. Small streaks of lace form around the glass on the drink down. Smell is of malt, citrus fruit, citrus zest, grapefruit juice, and herbal hop aromas. Taste is much the same with citrus zest and slight herbal hop flavors on the finish. There is a medium amount of hop bitterness on the palate with each sip. This beer has a lower level of carbonation with a slightly crisp and medium bodied mouthfeel. Overall, this is a pretty good beer that has a solid grapefruit presence all around, but it's a bit stronger in the flavor.

3.85/5  rDev -4%
look: 4.25 | smell: 4 | taste: 3.75 | feel: 4 | overall: 3.75

Appearance: Pours a clear amber color with an impressive head; nice retention and a significant amount of lacing

Smell: Citric and bitter, with a pithy grapefruit character

Taste: A bit of graham cracker, up front, and then there is a bitter assault on the taste buds; this is not a floral, citrusy hop blast but a pithy, aspirin-like bitterness; just a vague smidgen of the malt lingers into the dry, bitter finish

Mouthfeel: Medium body with moderate carbonation

Overall: This is quite a bitter experience and just what I would have anticipated from Stone, although the malt balance in many of their beers is missing from this one; not really the kind of hop profile I enjoy but one that a fan of really bitter beers might find appealing

4.11/5  rDev +2.5%
look: 4.25 | smell: 4.25 | taste: 4 | feel: 4 | overall: 4.25

With the always-arrogant hop dominance front and center, this special version of Ruination kicks those natural IPA flavors of grapefruit into hyper warp with actual citrus additions.

Pouring the steadfast hues of golden and amber, the ale carries a surprisingly filtered haze that strips any diffusion from the beer's appearance. It simply gleams in the glass and shows off its streaming carbonation brilliantly. Its ivory tinted lather builds on top with strong and long-lasting retention, lacing the glass beautifully as the ale fades.

Citrus aromas are backed with caramel for a perfectly imbalanced scent. The common focus on grapefruit is exacerbated by more prominent citrus character as the actual grapefruit pith, peel, juice and ribs all add as much of a leafy verbena-type character as the hops do. With just enough malt character to give a slim graham cracker note, the beer's hop dominance is evident.

Then to taste, much of the same transpires. High citrus character is of all things pink and white grapefruit- fully equipped with rinds, pulp and tangy fruit juice. The hops easily dominate the taste even as caramel and graham cracker rise first and further support the hops and fruit additions afterwards. Finishing with a leafy, stemmy sassafras herbal complexity, the hop bitterness and fruit acidity provides earthy taste to boot.

Medium-light on the palate, any residual sweetness is short lived as the malts simply dissolve off of the early palate. Its malty-dryness props up the hops as the intensifying bitterness introduces an acidic pang and hides its vegetative astringency well. Deeply resinous and spicy warmth close the session with high level of refreshment.

In theory, if the beer already tastes like grapefruit, then lets push that even higher by adding actual grapefruits to the beer, relying on the hop's "bigness" becomes its own complexity. But I would prefer richer taste by adding a different fruit to the mix- oranges, lemons, apricots would not only intensify the fruit character but give it greater variety as well.

4.08/5  rDev +1.7%
look: 3.75 | smell: 4 | taste: 4.25 | feel: 3.75 | overall: 4

A: The beer is slightly hazy amber yellow in color and has a light amount of visible carbonation. It poured with a quarter finger high white head that quickly died down, leaving lacing on the surface and a collar around the edge of the glass.
S: Moderate aromas of grapefruit and grapefruit peels are present in the nose.
T: Similar to the smell, the taste has flavors of grapefruit citrus from the hops but there almost seems to be nearly an equal amount of grapefruit zest, the latter of which stands out in the finish. There is a moderate to high amount of bitterness and this persists through the finish. Only slight traces of alcohol are perceptible.
M: It feels medium-bodied and crisp on the palate with a moderate amount of carbonation.
O: As advertised, the aromas and flavors of this beer are all about grapefruit, although the addition of grapefruit peel seems to mellow things out about and not make this as tangy as you would expect.

4.06/5  rDev +1.2%
look: 4.25 | smell: 4 | taste: 4 | feel: 4 | overall: 4.25

Pours a nice fizzy slight foamy 1/2 finger head that fades at a med pace but is reinforced by streaming bubbles from the bottom, nice soapy lacing, crystal clear honey orange color.

Nose brings nice hops, citrus, little grapefruit, some citrus zest and candied orange peel, hint of stone fruit as well, little juicy orange, as well as a candy malt base with some perceived sweetness and a hint of booze.

Taste comes on a bit sweet at first with a little candy malt, but that's quickly washed over but hops and grapefruit peel, a strong grapefruit peel flavor with bitter rind, little juicy grapefruit bursting juice packet, and a little orange rind and candied orange, mild clementine and even a bit of a spicy chewy hop profile. It's quite bitter and continues to increase the bitterness as it goes but eventually plateaus to the same as biting a grapefruit rind essentially. Then some mild alcohol with the sweet malts, it attempts to hide it but it shines through. Finish is super bitter chewy spicy hop profile with more grapefruit rind and orange peel zest bitterness, fairly dry but a hint of candy like malt lingering.

Mouth is med bod, nice carb, a bit of warming booze.

Overall not bad, nice big bitter IPA with a decent malt balance that gets a little sweet, the bitterness really ramps, but everything balances out pretty well in the end. The grapefruit rind comes through quite a bit and blends nicely with the hops. Enjoyable and tasty.

look: 4.5 | smell: 3.75 | taste: 4.25 | feel: 4.5 | overall: 4

The clarity on this beer is so sharp it's nearly unsettling. Hide the head and any traces of carbonation and you might think it was bourbon. Flavor is good with a thick hoppy think going on that is not overly done or obnoxious or out of control. What citrus is there is an accent that joins in and meshes with resin tones and spicy edges from hops. A nice drinker. Has some heavy tones on it but is fairly balanced. A nice one. Glad I picked it up when I did.

4.24/5  rDev +5.7%
look: 4 | smell: 4.25 | taste: 4.25 | feel: 4.25 | overall: 4.25

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.

Appearance: pours a crystal clear orange color with a 1" head that slowly falls to a spotty surface covering.

Smell: grapefruit and citrus tones are easy to detect.

Taste: grapefruit is up front along with orange, lemon zest, and mango. Bitterness is bold and alcohol is mildly noticable.

Mouthfeel: medium bodied. Crisp to start, less crisp and mildly dry at the finish. Long lasting aftertaste.

Overall: a very refreshing and citric forward IPA. Very enjoyable.

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

very cool beer, thinly veiled as something other than stone brewing, but thats cool. love the idea here, huge grapefruit hop buff, so this is right in my wheelhouse. i thought the execution overall was a little better than okay, but not as good as it could have been, or was in my head. a clearing orangey color, well carbonated with a bold white head that lasts. a nose as hoppy as it is grapefruity, plenty of bitterness, but some pale or maris otter malt backbone too. the flavor starts like a robust ipa, balancing grain and heavy handed hop additions wight he woodiness of centennial and the columbus citrus profile. the grapefruit waits until the end to show up, but it comes on strong. its all rind, not flesh so much, i get that bitter white pithy flavor, which is a really nice compliment to the hops, they both sort of play off each other, getting ever more bitter. the finish is forever, citrusy bitterness without the accompanying acidity. i wanted a little more fruitiness to this, and a little more sessionability. with all the bitterness and alcohol strength and malt body, its a very slow sipper for me, and when i was thinking of an all day style ipa with refreshing grapefruit, this is a little odd, but i love the idea, and maybe would like to see a series of these, one with flesh, one with ruby red fruit, one with pils malt, one around 4% abv… it would be a cool project. glad i got to try this beer, but i probably wouldn't buy it again.

The name is indeed "Stochasticity Project Grapefruit Slam IPA," not "Stochast...India Pale Ale." So props so whomever added this correctly. Bottled 01/29/illegible. (I assume 01/29/14). 1 pint 6 fl oz brown glass bottle with appealing label print and unbranded black pry-off pressure cap acquired at me local H-E-B grocery a couple hours ago and served into a Pinthouse Pizza conical pint glass in me gaff in low altitude Austin, Texas. Reviewed live. Expectations are below average given the brewery. Reviewed as an IPA since the label and description clearly identify it as such.

Served cold - at fridge temp. Side-poured with standard vigor as no carbonation issues are anticipated.

A: No bubble show forms as it's poured.

Pours a three finger wide head of very pale khaki colour. Okay creaminess, thickness, and frothiness. Okay complexion and consistency. Head retention is good - about 7-8 minutes. Leaves spotty inconsistent lacing on the sides of the glass as the head recedes.

Body colour is a transparent translucent copper of very good clarity and average vibrance. Clean; there's no visible yeast sediment or anything. Appears well-carbonated.

Overall, this is predictable standard fare for an IPA. Far from unique or special.

Sm: Soapy - I think this spent too long in primary. Bubblegum. Fresh citrus peel. Grapefruit. Faint pine. Floral hops. Fruity. Fairly resinous, but not real oily or nectary (much to my disappointment). The fresh citrus peel notes are a definite highlight for me personally, but the unwelcome bubblegum seems to drown the finer notes out. Maltwise, it's got a sweet bready undertone with plenty of pale malts and caramalts. Surprisingly, if anything it seems too sweet, not too bitter; did Stone brew this? I'm shocked they seem to have brewed an IPA without unnecessarily overaggressive hop bitterness.

Overall, this is a fairly pleasant clean aroma of mild strength, though it does seem too sweet and the bubblegum is unappealing.

No yeast character or alcohol is detectable.

Mf/T: Okay, right up front it's obvious this is too dry and pithy. It also comes off a bit stale and rough - which is disastrous for an IPA. Wow, this mouthfeel is poorly executed. Overcarbonated, soapy, and medium bodied. Slightly oily. A biteen coarse. Horrid presence on the palate. This is a poor texture for a beer in this style. I'd almost prefer a watery beer to this. Ugh. It just scrapes the tongue.

Not gushed, hot, boozy, harsh, or astringent. There is some tolerable alcohol warmth.

Soapy detergent dominates the flavour profile; this definitely spent way too long in primary. The backbone of the beer is a weak pale malt/caramalt core. I pick up on faint hints of graham cracker as well. Once you get past the soapiness, you're confronted with poorly integrated bubblegum tones. The pleasant citrus peel from the aroma becomes a bitter raw nightmare in the taste, and the grapefruit character is poorly executed. It doesn't quite have the bite of most grapefruit-based IPAs, but it has all of the pithy rindy bitterness. As a result, this flavour profile is soapy and off-putting throughout, but too sweet and bready up front and too bitter on the backend. Obviously, the imbalance is extreme. As it warms, I pick up on that stale orange juice note I always despise in IPAs - a note which lingers on the aftertaste along with the pithy bitterness. Ugh.

No yeast character comes through.

Lacks subtlety, complexity, intricacy, and nuance. The build lacks cohesion. Not a gestalt flavour profile by any means. Below average depth and duration of flavour. Average intensity of flavour. I'm having trouble liking this.

If the off notes don't get to you, the wretched imbalance will. I applaud the experimentation, but frankly this shouldn't have made it to market.

Dr: I swear I approach my reviews of Stone's beers with an open mind, but it sometimes seems like their hop choices and approach to brewing IPAs is just diametrically opposed to my personal tastes. This is absolutely not a beer I'd recommend to friends and not a beer I'd consider buying again. I'll finish this bottle without too much trouble - it's surprisingly drinkable in spite of its many flaws - but boy is this a sad attempt at an IPA. It's the kind of failure at brewing an IPA only Stone (and Green Flash) is (are) capable of. To all those who love this, I wish I was one of you. But unfortunately it's really not doing it for me. Not Stone's finest work, but then it's not a collaboration beer.

Surprisingly, it does get better (less bad?) as it warms. The bitterness becomes less obnoxious and the stale orange juice note picks up a little.

I'm surprised Stone has gone with this sneaky labeling approach. "Koochenvagner's Brewing Co" indeed. I tend to view Stone as a marketing company that happens to manufacture beer, but this marketing decision is somewhat confounding.

On tap at Capone's.

Clear, golden pour, with a thin white head that retained as a ringlet; minimal lacing. Nice aroma, obvious grapefruit, crisp leafy hops, promises of a pale biscuity malt profile. Blast of fresh grapefruit in the taste, pith, peel, and pulp, good balance of sweet and bitter, herbal/leafy hops, solid biscuity malts. No complaints here. Medium body, crisp mouthfeel with a dry finish, moderate to low carbonation. Pretty good overall. I'd imagine its charms wouldn't last very long in a bottle, so drink it fresh.

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: 4 | smell: 4 | taste: 4 | feel: 4.25 | overall: 3.75

Bomber poured into a stone standard pint glass. The brew appears a hazed, pale golden copper color. A sudsy white topping rests atop fading to a thin film with a curtain of lace sticking.

The aroma is all pulpy and zesty like rinds of fruit. It doesnt scream grapefruit but you certainly get that feel of citrus zest, pulp and pith. A little grassy as well but the nose leaves little room for anything but zest and citrus hops.

The taste is very dry and bitter. Pulp and zest of grapefruit pith/rind. A bit herbal and grassy with a resinous cling throughout. Despite it being dry, there is a light toast grain element before getting a bit piney.

This is medium to light bodied with a modest amount of carbonation. Overall not bad but not the slam of grapefruit I was expecting. I would rather take any other hoppy stone offering that is fresh, over this.

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

A: Pristine orange soft glow in the glass, with a soft mesmerizing rise of carbonation. A bready, dairy white colored head is a good size with high rate of stickage being left behind.

S: The nose is fresh grapefruit juice, a lightly dry sweetness of caramel grains, and some freshly cut orange. A hint of lime sneaks in with some fresh citrus and flowery hops on the finish. Decent level of awarness.

T: The flavor was bitter orange peel, grapefruit peel, with a some dry flowery hops, pine brush and dry, pale grains. Bittering level of dry hopped citrus, bready caramel with a hint of untamed laquer alcohol from the 8.2% that felt a bit out of place and misflavored.

M: Dry hopped flowery coating on the tongue, some oily hop resins mixes in, sticky, medium consistency.

O: Overall a lingering dry hopped bitterness stays awhile. Sticky oily hop resins with a dry finish. Very good beer, but think honestly the flavor complexity wasn't as bright or forward as expecting (maybe im comparing this to harshly to thier ruination) but still brought an appreciable amount of hop bitterness.

Pours a nice clear golden color with a white head and ample lacing. Retention is good and the beer looks the part. The aroma was expectedly citrus laden and a bit piney. In the taste, fresh pink grapefruit and rind. Some pine and hoppy grapefruit citrus and a sweet malt base. It tastes like a stone, with amped up citrus. Medium bodied, crisp, smooth and refreshing. Overall a tasty double ipa worth checking out for sure.

Golden to bronze in color with a fluffy head. The aroma does indeed bring some grapefruit, as well as citrus peel, pine, resin, alcohol. The flavor is just meh. A mediocre offering. Not even in the same ballpark as the Stone Enjoy By series. Muddled and boozy. Citric and harsh on the palate. Notes of cleaning solution and chemicals. The title was alluring, but this beer didn't deliver the goods for me.

22 picked up tonight at the COOP for a seemingly pricey $7... Pours with a short lived white head... little to no lacing... cap is spotty at best... the brew however is a polished golden... pretty, but needs work.

Nose seems spot on for a massively hopped So-Cal DIPA... grapefruit zest is certainly present, but honestly, IMO this leans toward a well done DIPA with the citrus just adding some background character.

Flavor is MUCH more grapefruit centric... pithy and a little oily.. moves into the hops easily but the pithy (almost English marmalade) notes seem a little too much and overpowering.

Very interesting.... would have been fine without the citrus zest and it works IMO but gets pretty unbalanced on the palate.

Glad I got a chance to sit and enjoy it by myself... but I doubt I will buy it again.

Pours a nice golden blonde color with a slight orange hue to it and a decent, frothy head into my glass.

Lives up to its' name in the aroma. The use of grapefruit peel gives a boost to the citrusy hop profile.

A definite grapefruit bomb here. Acidic with the perfect touch of bitterness and light buttery malt.

My only problem is that all the grapefruit notes can overwhelm those not used to a citrus-heavy IPA. Warms the throat with the perfect dose of lingering bitterness.

Perfect IPA for those who wish to drink their grapefruit and enjoy it too!

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

Poured from the bottle into a Spiegelau Dogfish Head IPA glass.

Real great looker, really reminds me of Stone Enjoy By, deep bronze and super crystal clear, with controlled carbonation, and just the right amount of it. Fluffy, large, tan like head, fistfull and big but in control off the pour. Clumps of lacing and spiral lines all around the glass, an IPA winner of a beer in the looks department.

Nose is rindy grapefruit, even a bit spicy strangely. Lots of zest and almost candied like, but not with some sweetness. There's a real neat earthy character to this as well, and a real wonderful green peppercorn spice aroma that just wallops. Grapefruit and pepper what a great combination.

A real winner in the palate. Matching bouquet in flavor. Earthy pepper and wonderful almost chile like heat. Green peppercorn warmth and earthy steak like meaty quality. Great oil slick palate but not syrupy. Popping hops and real coating oils with of course wonderful grapefruit aromatics and juicy flavors.

Juicy, peppery, hop forward citrus and great zest and Stone solid IPA quality. An interesting turn with the added grapefruit. Last added fruit of grapefruit beer I had was weal(and yes it was an IPA too). This though is a real winner.

I've had at least a couple of other IPAs with grapefruit peel added, but for the most part the grapefruit didn't add a lot- too subtle of a flavor in the amounts added. It's a logical idea, there being so much grapefruit peel flavor is so many hop varietals. If you could really capture that grapefruit flavor from the grapefruit peel itself, it should work well in the beer. No fear of that here- huge grapefruit peel notes. The citrus oils really come through here, and are the predominant flavor and aroma, although there is a nice nutty graininess that complements the citrus. Nice!

22 ounce bottle into tulip glass, bottled on 1/23/2014. Pours fairly crystal clear golden orange color with a 2 finger fairly dense white head with good retention, that reduces to a small cap that lingers. Spotty soapy lacing clings around the glass. Aromas of big grapefruit peel, orange zest, tangerine, pineapple, lemon zest, citrus rind, floral, grass, pine, light caramel, bread, and floral/grassy earthiness. Incredible aromas with huge citrus/floral hop and citrus peel aromas, with light-moderate malt balance; and great strength. Taste of big grapefruit peel, tangerine, pineapple, orange zest, lemon zest, citrus rind, pine, floral, grass, light caramel, bread, and floral/grassy earthiness. Good amount of floral/pine bitterness on the finish; with lingering notes of grapefruit peel, tangerine, pineapple, orange/lemon zest, citrus rind, pine, floral, grass, light caramel, and floral/grassy earthiness on the finish for a good bit. Damn nice balance and complexity of bright citrus/floral hops with grapefruit peel, and light malt balance; with a crisp malt/bitterness balance and zero cloying flavors after the finish. Medium carbonation and body; with a smooth, crisp, and moderately sticky mouthfeel that is great. Alcohol is very well hidden with only a light warming present after the finish. Overall this is an awesome DIPA. All around great complexity of citrus/floral hop and grapefruit peel flavors, with light-moderate malt balance; and very smooth and crisp to sip on for the ABV. A highly enjoyable offering.

A: Pours a lightly hazy golden apricot in color with moderate amounts of active visible carbonation rising from the bottom of the glass and moderate amounts of orange highlights. The beer has a two finger tall sudsy foamy off-white head that reduces to a couple of small to medium sized thick patches of moderate sized bubbles and a medium thick ring at the edges of the glass. Significant amounts of lacing are observed.

S: Moderate to strong aromas of grapefruit and citrus/grapefruit hops with some lighter notes of citrus/grapefruit pith and herbal hops. There is also a light hint of grainy malts.

T: Upfront there are light to moderate flavors of slightly sweet grainy malts with moderate amounts of white grapefruit juice. That is followed by moderate flavors of citrus/grapefruit, citrus/grapefruit pith, and herbal hops. Moderate amounts of bitterness are present and they linger well through the finish.

M: Medium bodied with just shy of moderate amounts of carbonation. Moderate amounts of dryness in the finish.

O: Definitely an enjoyable brew and it does not disappoint with respect to the grapefruit - both the grapefruit juice and the hops are very present in both the aroma and taste. Alcohol is well hidden in my opinion and the beer is refreshing. Matched very well with my homemade General Tso's Chicken - nice contrast to the sweet and spicy flavors.

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.

Pours a clear, gold color. One inch head of a white color. Good retention and good lacing. Smells of citrus hops, wet hops, hint of grass, slight alcohol, slight citrus, slight sweet malt, and a hint of earthy malt. Fits the style of an American Double / Imperial IPA. Mouth feel is sharp and crisp, with an average carbonation level. Tastes of citrus hops, floral hops, hop oil, sweet malt, alcohol, hint of grass, and hint of caramel malt. Overall, good appearance, aroma, blend, and body.

22 oz bottle poured into a snifter.
8.2% ABV, Bottled on 01/30/14

A - Clear golden orange, this beer is a cross between the yellow grapefruit skin and it's darker, pink pulp; frothy off-white foam caps the brew and splatters some lace on the snifter for added effect. A sexy looking beer to be sure!

S - With a name like Grapefruit Slam IPA, one might be inclined to expect some grapefruit up front. Stone's Stochastcity Project delivers on that promise with a nose of ripe, freshly squeezed grapefruit juice filled with pulp, as well as chunks of those delicious little sugary grapefruit candies. Sweet malt provides some base for this aromatic hoppy brew, delicately offering warming alcohol on the back end.

T - Traces of caramel creep through the big malty base of Grapefruit Slam IPA inserting sweetness into the mix of bitter grapefruit peel and piny, resiny hops while grapefruit juice leaves bitterness lingering on the tongue.

M - Stronger malt presence provides a rich and smooth base but rises to the surface creating a fuller feeling body and warming alcohol, even for the "lower" 8%. Both of these attributes aren't terrible, they just serve to diminish the delicate grapefruit nature of this IPA; it's bitter finish remains in tact, however.

O - Stone's Stochasticity Project Grapefruit Slam IPA, the first release of this project, is a fantastic beer, but one that seems to step away from what one might expect from Stone, especially in regards to their hoppy beers. Grapefruit Slam IPA doesn't scream double IPA in terms of it's hoppiness and while the aroma seems spot on, it doesn't quite deliver on the name's promise of bold characteristics of the subtropical citrus fruit. Finely brewed, it's certainly hard to put down this damn tasty brew, I just wish my senses were truly slammed with grapefruit.
