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.

The beer does not remind me much of grapefruit peel, but instead mostly of a Stone hoppy brew, and I believe this is Ruination with citrus peel.

The beer has a punch of hops of pine and grapefruit and citrus peel, onto a medium malt quality. The beer drinks quite easily, but does not separate itself with the grapefruit that is hidden.

Poured out of a 22 oz bottle into a Boulevard Smokestack tulip.

This is not my style, not even a little bit. But, this is pretty neat, for a style that lately seems to be about how much hops you can put in the its all pined out, this is a nice twist.

Pours out a dark golden hue, with a thin head, and nice lace. A seriously hopped up aroma, with a distinct citrusy grapefruit aroma...faint malt note. Not heavy malt, but malty nonetheless. Very hopped up flavor to open, slightly malty in the middle, and finishes out with more hop and the grapefruit mixed in for good measure. Heavy mouthfeel, medium prickly carbonation. Overall not too bad, not my preferred style, but I'd recommend this for something different...word of warning, this is a beer that is highly nuanced, it could; easily be took me a while to figure this one out.

Pours tawny golden hue .. Bright orange. Reminds me of the look of blue moon with a frothier head and more cloudiness.. A good sign. Head diminishes quickly into mild white bubbles clinging to the surface of the brew. Aromas of light fruity breadiness of malt..reminds me of an aged beer or barleywine scent. Must be from the abv. Some fruit but not as much grapefruit as I would expect in the nose. Taste does not follow the nose in this instance as the bitter tang of grapefruit is prevalent here.. Piney and bitter..almost too much so, but opens slowly as it warms. Boozy indeed but well balanced. Mouthfeel is foamy and refreshing.. Digging it for sure. Overall a refreshing take on an IPA.. Stone gets this style right every time for a reason..they know IPAs.

A: Cloudy, auburn/apricot colored beer. The head is fluffy and off-white, with a long retention and a ton of lacing.

S: Deep caramel malts, green apple and a ton of citrus. The citrus aroma hits you as soon as you open the beer.

T: The taste follows the beer really well. The flavor is a great balance of sweet and bitter. The beginning of the beer is all about the malts, sweet toffee flavor. Soon the bitterness from the hops come in, piney and citrusy. The taste from the grapefruit itself comes at the end, a bright acid note.

M: Moderately heavy body, almost chewy, with lots of carbonation.

O: A really tasty beer. a Great balance of sweet and bitter. I was surprised that they didn't use Cascade, but it almost seems that with Cascade it might have been too much. A well balanced, very drinkable beer.

Thrilled to find this in Joplin MO

Pours an effervescent honey color with 3+ fingers of rocky pearl colored head. Through the roof head retention & lacing

S: Some grapefruit, & a little pineapple & grassyness

T: Big time grapefruit & grapefruit pith up front., some bready sweetness, pear & passion fruit as well. Much more grapefruit as this warms, a little dryness & pineapple & a little more pear. Finishes with much grapefruit bitterness & some pineyness.

MF: Medium bodied, subtle carbonation, skews hoppy until it warms

Pretty damn grapefruitty

Very drinkable for the ABV, not completely in my wheel house, but this delivers what it promises... No complaints here!

Good One!!! Kind of like an "Avery Maharajah Lite". Less bitterness, lower abv.,more grapefruit flavor.

Pours a hazy golden amber color into a pint glass. Average white head with a little better than average retention. Some lacing.

Aroma is a big grapefruit presence with some additional hoppiness.

Taste is good and bitter ( not a total head shrinker but a good IPA bitterness) with more grapefruit flavor than most IPAs I have tried. The addition of extra grapefruit, in addition to all the citrus hops, makes the flavor really stand out.

Interesting mouthfeel. Good bitterness, including that from the actual grapefruit flavoring. Crisp and refreshing.

I would easily drink this one again. A well crafted brew.

Poured from a bomber into a pint glass

A: translucent gold, very thin head

S: sweetness of malt, a bit of citrus. Not a ton of alcohol notes for a 10% beer

T: this is where the beer shines. Taste starts bright and citrusy, and then finishes with a punch of grapefruit. Wow! One of those beers you need to drink a few times because there's so much going on.

M: creamy and smooth. Light carbonation

Overall: I really enjoyed this beer. Unique flavor of grapefruit really compliments what would otherwise be "just another IPA". I won't try to spell the name again though!

Poured a great golden, hazy body, 2 finger head, nice lacing. Smelled like it says, grapefruit, big malt presence in this one, bready at times, but for the most part the smell was citrus and pine. Taste wasn't as great as the nose, very 1 dimensional in terms of the hop profile. Mouthfeel was medium body. Overall, I wouldn't have this one again. I'm under the impression that anything Stone involved will have people automatically sucking their d*icks for reviews. This was a good beer, but not worth the price or flavor. This was okay.

A small white head on top of a perfectly clear, copper colored body. The aroma is full of grapefruit and pine with notes of caramel. Lots of malt up front with spicy hops. Finishes with pithy bitterness and citrus zest. Medium thick body, moderate carbonation, and a dry finish. Not bad, but the bitterness is excessive to the point of surpassing pith and reaching full on aspirin harshness. Drinkable, but they really seemed to have grabbed some of the more undesirable aspects of grapefruit.

BOD 2/7/14. Pours a slightly hazy light amber with a full head that retains the lacing quite well. Nose is of grapefruit over sweet biscuit malt. Medium bodied to the heavy side with a smooth texture. Low carbonation level with no effervescence on the finish. The flavor profile is well balanced and focuses on hop flavor rather than bitterness. It begins with a biscuit sweetness overlaying a robust grapefruit which flows into a flavor reminiscent of grapefruit rind. The finish is grapefruit rind with a touch of pepper. As it warms, the alcohol content is also evident on the finish. A higher carbonation level would improve the finish by bringing the grapefruit sweetness more forward. This one gets an outstanding by the skin of its "rind".

22oz bomber purchased from BevMo in Sunnyvale, CA. "Ale with grapefruit peel added" it says on the bottle.

Pours a beautifully clear, and fairly pale golden colour, with a fine white head that settles out to a fine bubbled film. Lacing is patchy but good. Body has some weight behind it, and allows carbonation to form in powdery waves. Looks great.

Nose is also great. Big peely citrus characters, bright and sharp: piercing in intensity. Under this is a distinct sweetness, like a clear but flat honey malt. The two characters don't integrate all that well, but they're each quite pleasant in their own right.

Taste is similar, although the sweetness takes on a slight marmalade character what with the citric bitterness from the hops and the grapefruit peel. This bitterness probably comes fairly strongly from the peel, as there's a acidic quality to the bitterness—different from the sharper, earthier tones you just get from hops. It integrates fairly well, but it's also maybe a tad too aggressive. Feel is glassy and smooth, with some weight behind it.

Overall, there's no doubt this is a good beer, and a big beer. I'm afraid it may be too much for me: it feels a little unbalanced, while still seeming very sweet and very bitter. But there's stacks that's good in it—it's just not the beer for me.

Grapefruit definitely complements an IPA. I recently had an Abita that worked great, and this one is similar, but on a grander scale. It definitely is not as easy drinking and it probably costs at least twice as much.

It has an amazing yellow color and the foam and head are plentiful. The aroma is to die for. A huge mix of hops and grapefruit.

The taste is a wonderful balance of large amounts of malt and hops, cut with the fruit. The fruit really kicks in on the aftertaste, and it is a great effect.

This is definitely a great one to try. I am going to hog the entire bomber!

A nice summertime beer for the back yard on a hot day. Not as grapefruity as I expected, basically a citrusy but balanced light-bodied IPA. Would drink again, despite the blatant fruit inclusion.

Hoppy, refreshing, slightly citrusy, and pretty easy-drinking. Good hot weather beer.

Appearance: cloudy gold/ amber, finger of white head settkes to lacing that tightly hugs the glass.

Smell: smell is a faint, but very pleasant grapefruit aroma, mixed with some malty sweetness.

Taste: very unique, malty sweetness hits you first, followed quicly by a delicious grapefruit taste, and a bit if bitterness, but much less then expected.

Mouthfeel: carbonation is quite mild, body is full, dryness in the finish.

Overall: very unique, delicous in an IPA kinda way, but not an ipa, highly recommended.

I bought a bottle of Grapefruit Slam in a bottle shop. $7.99. Poured in to a tulip.

Pours a deep gold color, clear, with a frothy white head. Silk screened bottle is nice, and has a lot of written content.

Smell is a strong pine and citrus aroma. Predictably I guess?

Taste has a lot more sweet bread flavor than I was expecting. I had this figures for a super wet hop bomb, but the flavors are remarkable well balanced.

Mouthfeel has some body to it, dry, bitter and a bit cloying.

Overall not bad. Not worth the price, and with the grapefruit rind as an adjunct I make it something of a gimmick beer.

Poured into a balloon glass.

Look: Faded burnt orange body, cream colored head that calms to a bubbly film. Light lines of lacing.

Aroma: Massive citrus, grapefruit, a glue aroma, citrus rind.

Taste: So bitter I pucker. Grapefruit juice, pine, hops.

Mouthfeel: Really thin and hot. Boozy.

Overall: It's so bitter that I can't enjoy it. I feel like I'm drinking glue.

Appearance - a cloudy golden pour, two to three fingers of white foam. Big bubbles in the middle, lots of dotty lace around the glass.

Aroma - yeah, some citrusy aromas for sure, tart grapefruit but not as intense as I'd expected. Good resilience though.

Taste - brief sweet malts, covered quickly by the bitter hops. More grapefruit rind flavor than the actual fruit, bending this more to the bitter side. Slightly better balance as it warms. Pretty decent grapefruit representation. A dry finish without going too bitter at the end, and a rather nice warming.

Mouthfeel - somewhat weighty, medium carbonation, good smooth feel.

Overall - my only real comparison flavor-wise is two brothers sidekick, which I think represents grapefruit flavor better in a lighter brew. Glad I tried it but I like sidekick better.

A - Bright and vibrant clear orange, slightly off white head that stays thin and disappears, soapy lacing on the glass.

S - Citrus up front, big grapefruit notes burst through but are met with a caramel sweetness that makes it all quite pleasant.

T - The caramel sweetness in the nose gets lost behind a wave of huge citrus and grapefruit meat, pith and rind. Mild floral spiciness lays underneath. Medium hop bitterness meets bitterness from the grapefruit. I imagine this is what biting an unpeeled grapefruit would be like, it smacks your palate around. Did the flavor go too far? Maybe.

M - Medium heavy body, less carbonation than I'd expect from an IPA. Prickly feel on the tongue, this may be the grapefruit, clean finish with not as much lingering bitterness as I expected.

O - Some constraint here may have made this epic, maybe even mixing in different citrus to get the sweetness up to match that big grapefruit blast. Glad I tried it.

After the utter abomination that was Crime, I should really take a break from Stone beers, but I like the idea of grapefruit added to grapefruity hops. 22 oz. bomber split with my wife.

The pour is a dark orange you could play shadow puppets through; moderately carbed. Sans surprise, this is akin to the One Ring of citrus in the nose. I'm sure the grapefruit it contributing but this comes up my nostrils more citrus that g-fruit, though it's there, & more fruity than hoppy, if that makes sense. Light.

Grapefruit Slam IPA goes for extreme & obliterates the mark. Wow. Stingingly angry grapefruit & citrus swamp the palate. Bitterness that is hops plus - must be the grapefruit peel - desensitizes the tongue after just a couple of sips. It's hard to pick out anything under the wall of sensory deprivation, but mid-palate there's a spicy zest, quick shot of Dove (ugh - anybody else have that experience when you were young & had a vengeful mother?) doesn't do any favors, herbal tea. Finish is back to all bitter, all the time.

Love the aggressiveness. This creation sticks seven or eight toes out over the Gone Too Far beer abyss, but somehow manages not to topple over. A very good brew that's right next door to excellent.

I was really excited to see this on tap, appearance - great, looks slightly hazy but overall very appetizing. Nose- expecting to get punched with grapefruit/citrus but not here. Does show some fruit but not what you would expect. Taste- Holy grapefruit! For me it's over the top and not balanced. Has a nice mouthfeel and finishes dry but really disapointed overall. This beer = sucking on a very bitter grapefruit rind while drinking an IPA. Won't get again.

Reddish-gold body. Medium white head.

Nose is less than I expected. Crisp, clean citrus, but just not enough of it.

Flavor is definitely grapefruit all the way. Super light malt body barely makes an impression. A hint of black pepper as well, (of all things). Just a tangy, tart taste sensation.

Mouthfeel: Grapefruit on the finish takes the enamel off my teeth...and I love it!

Superb drinkability. Great overall brew. The only real hit is the lesser than expected nose.

Pours a golden amber color with a huge pillowy white head that slowly settles. Left a nice wall of lacing on the glass.

The aroma is of grapefruit hops but it also has a noticeable tropical fruit hop scent. There is some candied apricot and pineapple. Some pepper. Sweeter aroma than I expected.

The taste is more tropical fruit than grapefruit. Some pineapple and apricot are forefront with grapefruit and its peel secondary. There is a bready sweet malt that provides some honey flavors. A peppery hop bite in the finish.

The feel is moderate with weakish carbonation. Its sweet on the palate, almost slick but then comes the bitter grapefruit peel and grass. The beer has an aspirin like dry finish.

A good DIPA but not quite the hop profile that I like. And according to its name, I was expecting more grapefruit. Maybe I waited too long to drink it.

Bottled on 1/20/14 at 43 degrees into standard pint glass
Aroma of grapefruit
Head average (3.5 cm), white, creamy with some rocks, rapidly diminishing to
Lacing average: short lumpy chains covering arcs of the glass, bubbles ranging from small to medium
Body medium yellow, slight chill haze
Flavor begins slightly bitter becoming astringent toward the end; no grapefruit flavor; no alcohol, no malt, no diacetyl.
Palate medium, watery, lively carbonation

I’m disappointed. I eat a couple of cases of grapefruit each season so I known the flavor well; there isn’t any showing in this ale. The grapefruit aroma is there and is underwhelming, and the flavor ends with the grapefruit rind and reticulum bitterness, but where’s the flavor? I was really looking forward to this ale – it looks and smells appealing and has good mouthfeel, but the flavor is not good.
