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.

I typically do not enjoy beers from Stone Brewery, however The Grapefruit Slam is an amazing beer. Wonderful floral citrus nose. But it is the finish on the beer that blew my mind. Subtle waves of sweet grapefruit flavors. Going to go buy all the bottles at my local beer guy tonight!

This beer is probably an acquired taste but believe me it really, really, really hits the spot on a hot summer' day or evening in the SW desert! Slightly tangy with grapefruit which is most definitely discernible without spoiling the taste of a light pilsner style more than IPA in my opinion, but ultra refreshing. Beware - it's strong! That's the IPA kick :) I can't get enough if it!

Poured from a 22oz bottle (Bottled On: 2/06/14) into a 12oz, Saxo branded, large mouthed, stemmed tulip. Although the artwork might seem random, it is quite amazing. Step back a few feet and you will see the gargoyle art in the chaotic lines of the 62,560 pixels used.

A- A conservative pour reveals a gorgeous, crystal clear, deep orange/copper hued beer with 1-finger's worth of a white, frothy head. Despite the non-nucleated glassware, a few conservative streams of carbonation emanate from the bowels of the glass. (4.75)

S- The grapefruit adjunct was immediately detectable...but hit my nose as being closer to a white grapefruit 'flesh' as opposed to the advertised 'rind' component from the fruit. After the initial sip and allowing the senses a moment to adjust, the intense grapefruit aromas fade rather quickly in favor of those familiar resinous, black tea-like aromas that is nothing but classic Ruination. Hints of other citrus and tropical notes (lemon/lime, peach, honeydew melon) from the Centennial dry hopping reveal themselves, but never dominate...the grapefruit is the steals the show with this offering. (5.0)

T- Grapefruit, grapefruit and more...yep, grapefruit. The palate is consumed with that very citrus fruit across the entire palate and its bitterness lingers well after the sip. As it warms, some of the other flavors as detected on the nose come to the party, but never dominate. However, I feel that the grapefruit 'peel' addition mellows the intense piney qualities found in standard Ruination. Despite 8.2% ABV, the malt stays well at bay, masking the alcohol completely. (5.0)

M- Stone's beers are never overcarbonated and always tend to weigh in on the more conservative side (IMO, 2.50 - 2.55 vols for all you brewers) and is no different here. Carbonation is on the softer side of medium and just enough to get the job done. Like its cousin, Ruination, the body of this beer ranks on the lighter side of medium. Hefty enough to support the generous more and no less. (4.75)

O- A really nice variation and surprising improvement to an already proven (and recently amended), world-class offering. Although I have yet to perform a side-by-side comparison, I think I prefer this a bit more than Ruination. The addition of Grapefruit peel/flesh helps bolster the citrusy character from the Centennial dry hop as well as tone down the piney (i.e. 'dank') component from the Columbus...the result is a more balanced, yet just as pungent (aromatic and flavor) offering. However, due to the increased price for this 'special release,' I will be more than content sticking with Ruination (5.0)

This is a great beer, hope they make it more often. I happen to like grapefruit, and my IPA's, so when I have described other IPA's in the past has having a "grapefruit" taste or aroma I take it all back about them. THIS baby does have GRAPEFRUIT. Really is a nice refreshing beer, light, hoppy and they used the kind of hops that really have a potent scent to them and as others have commented before now; it is very light on the malts. This is a bitter, but refreshing beer, not a lot of sweet available. Am I describing a "fruit" beer? NO. It has got that grapefruit rind (maybe a little of the oil too), contribution rather than juice. More like a good double IPA swallowed while someone shoved grapefruit peels up my nose.

All in all a very interesting experiment that I like very much, and I am drinking it on a sunny 75 degree day!

This has been the best new beer I've had this year. The grapefruit is intense, and it's a bitter paradise with this IPA. The grapefruit could have killed this beer, but it didn't. It made it more intense to the pallet in the best way possible.

Wish this was a yearly offering.

This beer is fantastic. Really surprised by how much I enjoyed this special release by Stone.
Nose is completely dominated by grapefruit, first time I've been able to really pinpoint one dominant flavor in an IPA.
Taste follows, much more sweetness and citrus than regular ruination. I prefer this 100x over.
Mouthfeel is what you'd expect, medium carbonation. Beautiful lacing down the glass.
Can't get enough of this beer, I'd order it over and over again.

This one was such a huge surprise for me! So fresh and delicious! The aroma was very nice with the scent of a freshly squeezed grapefruit. But, the flavor was sensational! Fresh grapefruit juice meets a perfect fresh hop balance! The mouthfeel was fantastic as well and everything you could hope for from a big IPA. What a combination this was! I've tried Pliny, Alpha King, Zombie Dust, Permanent Funeral, Nugget Nectar, Hopslam and a bunch others. I'd honestly have to say this is a t top 5 IPA for me hands down! Wonderful!

I had a hard time not just giving this one a straight 5.0. This is a pretty amazing IPA.

A: A very light amber, almost gold.

S: Great aroma, the grapefruit is very detectable, a great hop bouquet, the perfect combination of pine and citrus.

T: A modest hop bitterness balanced with a sweet malt bitter hop mix mid palate, with a bit of a sharp, dry, finish.

M:Perfect full bodied.

O: One of the best IPA's I have had. If you like Stone's style of IPA you will love this. It only takes a second to Enjoy By.

I am in love with grapefruit and this hits the spot, just like biting right into a bitter grapefruit in the morning! Great smell as soon as you open the bottle and the great bitterness of a real grapefruit on your first sip and the aftertaste doesn't stop!

Tried on tap at Magic Tree in Boardman Ohio. WOW! Punch in the face hoppy grapefruit aroma, followed by incredible grapefruit citrusy flavor. They nailed this one! Had at least 3 of these during my meal. Could've had a couple more, but had to work the next morning. Nice light-med golden color, very smooth going down, a very well made dipa. I was worried at first that the grapefruit zest might be too overpowering, but they balanced it perfectly to accent the hop profile.
If you like cascade, centennial, and citra, you'll absolutely love this! Quite possibly placed in the top 5 of my favorite beers, definitely in the top 10.

Poured into a snifter/wine glass/tulip hybrid

A - BEAUTIFUL copper/blood orange sunset, one finger fluffy white head and some sugar legs

S - wow, GRAPE FRUIT (slammed me in the nose, seriously!), sugar, soil, wet hops, kush, sharp bite of citrus and mostly grapefruit rind, baked/roasted malts, booze, floral perfume and a bright sunshiny mountain morning!

T - Grapefruit (with all of the wonderfully bitter sweetness), some nice booze, sugar, huge malts, HUGE citrus hops, pine, mango, slight pineapple, slight floral, fresh cut grass, mary jane and the great outdoors!

M - Medium to full body, well balanced (hops is over the top but nice), Good complexity and a long sugary hoppy goodness

D/O - Even being over the top with citrus and hops, this beast is refreshing, crisp, very clean, and all together tasty! I could rock this dude on the regular for sure! I bet with a wax cap, this dude could last years. Hops would calm down but maybe be even more gorgeous and the malt would be even more sexy!

Final thoughts - at $7 a pop and 8+ abv, this dude is a hop (specifically citrus hop) bombers dream! Tread lightly and often!

Orange color with a good head and lacing
Citrus smell with definite grapefruit odor
Clear, crisp, fresh taste. Strong citrus-grapefruit- at the start with strong bitterness at the end
Medium mouthfeel with some carbonation
Overall a good, crisp IPA with great citrus and bitter ending. Good ABV. Glad I tried this brew and may well again.

Another winner by Stone, poured into a Stone old guardian 10.5oz glass.

A: Similar to the enjoy by, a little darker, maybe more close to their IPA color. 1 and a half finger white head that dissipates to a thin/spotty layer. Not overly carbonated, very few bubbles rising to the top.

S: Smells great, grapefruit hits you right away, nose is very similar to Ruination. I'm getting a really funky hoppy grapefruit smell with just a slight bit of alcohol.

T: Bitter bitter bitter, Stone's signature of course. Grapefruit, hoppy, bites your tongue, VERY similar to Ruination. Very citrusy, orange zest, the aftertaste is grapefruit absolutely delicious, leaves your mouth/tongue feeling like a hopped up grapefruit blew up in it.

M: Zesty, sharp, carbonation yet no too much. Mouthfeel is almost perfect, not too light not too heavy, the bitterness bites your tongue and yes it is pushing overly bitter it's just about perfect. Yet I wouldn't call this sessionable, one bomber will be more than enough.

O: Overall this is very similar to Ruination, it has been over 4-5 months since I have had Ruination but if I did a side by side blind taste test I might not be able to tell the difference, I am only about a year and half into the craft industry (had my fair share of IPAs) but I am still acquiring the art of tasting different hops/fruit flavors in beer. In the end this is a typical Stone IPA, it's overly bitter which I don't mind one bit, it separates the boys from the men, as well as it's Stone's IPA signature, but the flavors make up for it, especially how well the alcohol is hidden. This would be a beer to DEFINITELY seek out on draft, I know I will. $7.50 for a bomber from Total Wine (30 mins away) is not too bad. In town at local stores I'm sure I will see 8.99-9.99, I will probably buy 2-5 more bombers over the course of the spring/summer.

Added: 1 glass down, this leaves your mouth and lips just coated in a sticky sweet grapefruit hop mess, it's delicious. I will have this on draft that's a fact.

Great beer from my old hometown Brewery, this is a hoppy citrusy IPA lovers dream, seek it out and you won't be disappointed! Great job Steve and Greg!

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.

This is nothing other than stone's ruination ipa with grapefruit. A very highly hopped, high quality ipa with an added dose of flavoring which many west coast ipa styles should have plenty of. Color is straw and akin to any double ipa. Smell is where the grapefruit shines as it gives way to some booziness. Bitter orange is also in the along with spice and pine from the centennial hops. Taste is pretty good....just as you'd expect; ruination with bitter grapefruit. Some heat from the alcohol. This beer is very bitter and not sweet at all. It's a great take on the classic ruination and definately trying at least once.

A - Two fingers of dense white head over a crystal clear pale yellow body. Incredible retention, the head never leaves, and lots of good lacing.

S - Lots of grapefruit citrus as the name would suggest.

T - Nice bitter hops upfront; grapefruit, pine and floral. But then comes a rush of earthy smokey malts. Alcohol is subtle and masked by the big hop and malt flavors.

M - Medium body with moderate/high carbonation. Not very sticky, slick and refreshing.

O - What a great surprise and happy to get this on the East coast. After reading the label I was concerned that it would be overly fruit flavor. Instead what I got was yet another fantastic West coast IPA with massive hops taking center stage. However, I was impressed with how nicely balanced it is with a big malt base that comes through without overpowering the hops. Nice and complex, there are plenty of great flavors to take note of. I will most definitely be picking up more of these!

...and as I write this I now realize this is brewed by Stone?! That was not obvious from the bottle but should have been from the taste. This seals the deal, Stone Brewing is hands down my favorite large craft brewery. Although it's still a tight race with Sierra Nevada and Green Flash.

World of Beer exclusive

Appearance - looks very typical. Average lacing.

Smell - HOLY GRAPEFRUIT. That is all.

Taste - Like a very subdued version of ruination, where all missing taste is replaced with grapefruit. I'm actually surprised, given that this is a stone beer, that the hop flavor is taking a backseat to grapefruit.

Mouthfeel - Pleasant, a very good viscosity for an ipa. An unremarkable carbonation, which I typically think is a good thing.

Overall - I really like it. I've never had anything close to this grapefruity. It's not as good of an ipa as regular ruination, but I think it is as good of a beer.

L: Pours copper tinted amber under a 2” cream colored foam cap that persists and provides sheets of lace. S: Big grapefruit nose, both added and hop driven. T: Rich malt attack provides a slightly sweet backdrop with added grapefruit, grapefruit rind and hop derived grapefruit flavors playing off one another. F: Medium to medium full body, medium carbonation. O: the interactions of the various grapefruit elements make this a very interesting beer.

Pours a clear golden color with a tight, white head that leaves good size chunks of lacing..

Smells of big grapefruit notes with some pine.

Tastes of the big hop notes with a solid malt backbone. Hops lead off with big grapefruit notes accompanied by some grass and pine with plenty of bitterness. Malt notes come through and cut the hops with some caramel sweetness and toasted grain notes. Hops come back in with finishing bitterness and spice. Alcohol is a bit noticeable.

Mouthfeel is medium with a slightly assertive amount of carbonation.

Overall, this is a great DIPA if you like grapefruit.

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 had two bottles of this beer in my possession that were both bottled 1/23/14. It arrived at the bottle shop I go to late and didn't get a chance to drink it until March I believe.

Great looking DIPA with an orange/yellow appearance with a nice, almost soapy like head that stuck around for a bit as I drank it.

The smell was incredible and was definitely one of the best aromas my nostrils have experienced so far. This is where you get slammed with the grapefruit. HUGE citrus and grapefruit on the nose. If I had a day old bottle it probably would have permeated throughout the entire house.

At two months old it was still a great tasting beer. Big grapefruit and citrus flavors, but definitely not as impressive as the smell. After each drink I remember smacking my mouth due to the grapefruit bitterness and overall "sticky" mouthfeel to it.

As good as it was at two months old, I figured this would be an IPA that would hold up for a while longer. I had the second bottle about 2 weeks ago and it was like taking a shot of liquor and chasing it by chewing on a grapefruit peel. Just plain booze and bitterness. Not slamming the beer at all, because I loved it the first time. This is just a warning to those who might stumble upon it in a beer shop. When Stone has a beer that says "Enjoy Fresh" on the label I should probably take their word for it.

Got this on draft at Row 34 in Boston, MA. Served in a snifter.

Little to no head. Crystal clear. Golden orange color. A swirl brings bubbles to the surface that quickly fade.

Outstanding aroma. Fruit and resin dominate. Very strong aroma. Nothing to search for. A swirl makes the aroma even more intoxicating. One of my favorite noses on a beer.

Up front citrus bomb. The bitterness is subtle and balancing. Alcohol is present but not hot or solvent like. Alcohol adds a sweetness that brings some balance to a typically out of balance style. Reminds me of Heady Topper.

Creamy mouthfeel. Almost feels oily, which may be due to massive hopping. Still crisp finish due to bitterness and high carbonation.

Great beer overall. Especially for those who can't get enough hop flavor.

This is an incredible beer....I bought it at first sight (2 bombers for $6.99 each), because I am obsessed with grapefruit, and therefore centennial hopped ipa's in general.

To be honest, I'm slightly disappointed with this beer only because there isn't enough grapefruit peel in it...I bought it thinking "Finally, A beer with so much b-myrcene and d-limonene that I will make an awkward face after ever sip, and then love every minute of it.

What I got was a somewhat average tasting IPA. And by average, I only mean that these flavors can all be found in other beers. It is definitely a delicious, well-rounded brew. I was just expecting a more aggressive usage of the grapefruit peel.

As my rating suggests, I would still highly recommend this beer to everybody. It is excellent, as are all of Stone's beers. It just didn't live up to the "grapefruit slam" name that it was given. I was expecting to get on here and rate this beer 5/5, because I have been looking for a beer heavy in terpenes such as myrcene and limonene, so heavy that I will almost gag at the flavor capacity. Instead, i tasted a brew that is quite good, in my top 20 of all time probably, but not what I expected it to be.

I would prefer a more aggressive profile, especially with the name "grapefruit slam"....It was more like a "grapefruit acknowledgement".
