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.

Grapefruit Slam

Bottled 1/23/14, poured 2/18/14.

Appearance: Deep gold, almost orange color. Perfect clarity. Half finger of fluffy white sand head sticks around. Not much lacing. Lot of carbonation streaming from the bottom. (4.5/5)

Smell: Hopalicious. Pine and grapefruit, surprise surprise. Smelling really fresh. Pleasant as hell on the nose. Not a huge depth of aroma, but this doesn't need it. (4.25/5)

Taste/feel: The feel is the first thing I notice, and good God, that's nice. A creamy sort of medium mouth feel with a moderate carbonation that mellows out the somewhat harsh hoppy, grapefruity bitterness. Big grapefruit up front with a bittersweet finish of pale malts and hop resin. Not a legendary tasting sort of beer, but the mouthfeel definitely bumps this one up a tick. Incredibly easy drinking. (4/5, 4.5/5)

Well done. There's an awesome balance here. The hops are heavy, but mellowed by the nice amount of malt and smooth mouth feel. Bitter one second, sweet the next, though I'd overall say it's more bitter than sweet. Another great one from Stone.

Stone Stochasticity Project Grapefruit Slam:

Appearance: Light amber caramel in color, great clarity and heavy carbonation visible right off the bat. Wonderfully thick, fluffy head in an off white egg-shell color. Head took a good three minutes to dissipate, leaving a rim of thick foam around the rim. Actually, as I am watching my husband consume this beer without cares, the lacing is present all the way down the glass- very nice!

Smell: Sweet malt hits first, followed by piney hops. Not much fruit on the nose, but the caramel malt is definitely present.

Taste&Mouthfeel: Wow killer carbonation! My favorite part of the beer is always the carbonation, and this is just fantastic! The thick malt of this IPA is very nice. Rich, thick over the tongue. The hops are definitely piney over citrus. Slight grapefruit hits the tongue late, on the directly on the bitter receptors.

Overall: Very interesting beer. If they were going for a "grapefruit beer" this does not fit the bill. But as a very rich, deep, malty and seriously bitter IPA, oh yeah, this is the stuff! I happen to love this beer. Not what it's supposed to be, which bothers me, but overall a very solid, strongly flavored IPA .

Grapefruit Slam!

Pale golden color with a tangerine glow. Low lying foam subsided to little.

Super C-hop leafiness and citrus notes with a wham-bam-thank-ya-ma'am of grapefruit peel and flesh. Still IPA hop intensity. Pale malts have a wet crackery vibe. Nice nose!

Slammingly hoppy with big juicy and tart grapefruit flavors upfront. Light pale malts have a tinge of sweetness. Lots of rind, peel, pith, and raw hop leaf. Notes of hemp and bitter greens. Awesome!

Crisp and quenching with a rigorous carb and bitterness combo that I love.

Really wanted this one. So worth the effort!

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.

3.84/5  rDev -4.2%
look: 4 | smell: 3.75 | taste: 3.75 | feel: 4 | overall: 4

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.

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

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.

Surprisingly good. I was convinced to buy this from the guy in the package store. I have never been a fan of fruit flavored beer, but I'm always willing to give anything a try. It was excellent. Very nice IPA with more than a hint of grapefruit. They actually complimented each other really well. I was a bit expensive, but I would definitely get it again. Highly recommended. Thanks to the guy in the liquor tore for recommending it.

I don't review beers. However, I feel compelled to prepare you for what you are about to experience. It is awful! I was genuinely looking forward to this. You know that back-of-the-throat taste you have after puking? This is it. Imagine taking a bite of the rind of a grapefruit and then grabbing an IPA to cleanse your tastebuds of that terrible, lingering taste only to discover that it's no help.

I will say that it poured a beautiful ruby/orange color with an inch of pillowy head. On the nose, I got not so subtle hints of, you guessed it, grapefruit. Oh, and a pine tree.

After an 8 oz pour from a 22 oz bomber I drain poured this with confidence and woke up the next morning with a horrible, puckering astringent taste in my mouth. Proceed with caution.

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!

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!

22oz bottle poured into an IPA glass, bottled 1/30/14
A: Pure orange, lots of little bubbles, two+ finger head that lingers
S: Grapefruit zest, grapefruit juice, tons of greapefruit. Also some pine resin and a touch of caramel
T: Again just loaded with all parts of the grapefruit, especially fresh juice. Pine on the midpalate, caramel and some bitterness on the finish
M: Medium-bodied, crisp, long finish
O: Perhaps a little one-dimensional but incredibly flavorful. Intriguing and well made

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!

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.

Couldnt tell this was a Stone beer. The clerk had to tell me.

Poured into my usual glass and got very clear dark gold beer with meringue like head and great lacing.

NOse is tropical, spicy and of course grapefruit.

Taste is intense. Grapefruit, malt, hops. The finish, in some ways, is stronger than the initial taste. Grapefruit peel is really there!

Mouth feel is about as good as it gets. Just right carbonation and not dry. Alcohol is not overwhelming. A unique and well done beer.

Pours a medium orange with a one finger off white head with some nice lacing. Aroma is of citrus peel (a lot of grapefruit), pine, herbal hop noes, sweet malts, and some tropical fruits. Taste is citrus peels (grapefruit mainly) resiny pine, herbal hops, tropical fruits, sweet malts, and some light bready malts. Has a medium body with a semi creamy mouthfeel and a semi dry, moderately bitter, medium-long, grapefruit dominated bitter finish.

Bomber to snifter, bottled 1/23/14

Pours a nice vibrant golden orange with a finger of foam and great clarity. Retention is okay, as is the lacing. Mild/moderate carbonation stemming from the sides, not bad looking

Smell is a citrus hop bomb, as expected. Grapefruit, lemon and lime, orange and tangerine, along with a big dose of pine. Sweet bready malts come through in the back with a touch of alcohol

Taste is with the nose, strong grapefruit and pine followed by a lot of other citrus- lemon, orange, a bit of tropical fruit. Malt profile translates well, sweet and bready with a splash of alcohol on the finish

Feel is really bitter with a moderate body and dry finish. Alcohol concealed pretty well, highly drinkable

Overall a really great beer. First time ever hearing about Stone's Koochen Vagner project. Hope they keep releasing things as good as this

Bottled 1/23/14 (about 3 weeks old).

A: Pours a clear gold. Tall, frothy and fizzy white head (maybe off-white). Good head retention but moderate sticky streaks of lacing.

S: Welp, grapefruit. Duh. Lots of of bitter, pungent grapefruit. Some spicy, resinous pine as well backs it up. No sign of malt. Duh.

T: Surprise, surprise, grapefruit. Followed by more grapefruit. Bitter, sharp, pungent grapefruit through and through. Grapefruit bombs everywhere. There is that spicy, resinous, dank pine that backs it up quite well. This spicy resin continues once the grapefruit has faded out, well into the finish and aftertaste. The aftertaste is spicy and bitter at the same time. Lots of super dry and bitter grapefruit peel but the spicy resinous dankness holds its own. No real noticeable malt anywhere but I'm sure it's hiding somewhere to help balance.

M: Medium-heavy, bitter and dry.

O: "Grapefruit slam" indeed. A nice highlight of grapefruit-y hops and actual grapefruit. Big, bold and bitter. Just enough accompanying hops to give it some backup and some complexity. Regardless, this is still a showcase of grapefruit and it executes it well.

Twenty-two ounce bottle, dated 1/30/14.

A: Pours a clear orange with a 2" white head which fades slowly to the rim and cap leaving spotty lace.

N: Juicy and pungent grapefruity citrus, floral, honey and malt.

T: Enormous grapefruit presence, pith and peel, resiny and almost piney with a mild malt backing for balance.

M: Moderate body and semi-full carbonation. Finishes with a lingering bitter grapefruit finish.

O: One dimensional and singular grapefruit focus if that is your thing. Refreshing.

22 ounce bottle, bottled on 01/30/14. Served in a DFH IPA glass, the beer pours a clear golden/orange color with about an inch and a half off-white head. Head retention is good, and there's a lot of lacing. Aroma is nice, the brew smells like citrusy (grapefruit) and pine hops, along with grapefruit peel. The taste? Good bitter grapefruity hoppiness is that this beer is all about! There's also some spicy hops, sweet/bready malt and some earthy flavors noticeable too. Mouthfeel/body is medium, it's slick with a good amount of carbonation. I liked this brew a lot, it's definitely worth trying. Hopefully this isn't a one time brew because I'd like to try this again in the future. $6.49 a bomber.

I'm always excited about a special release from Stone and this one's no exception. This offering begins by pouring a handsome but unremarkable golden straw color with an almost greenish hue. It poured with a generous thick foamy white head that gave way to a offwhite film and substantial lacing. The aroma is very citrusy (obviously) with hoppy pine and resin notes and a little malt to offset the bitterness. The flavor follows suit. Super bitter tons of citrus and very very refreshing. It is a simple ipa and rather one note but that one note is damn good. Keep it up Stone!!!

Golden Honey color, light wheat, slight carbonation and a slight head. Very, in-your-face grapefruit/citrus smell. I small hint of dark corn syrup bordering on molasses on the nose as well. Very hoppy/grapefruit juice on the palate. Definitely some bitterness but nothing crazy. Minimal maltiness but this doesn't take away from the beer, especially considering the 90+ IBU. Overall very crisp, refreshing and pretty easy drinking but the grapefruit presence and hops are there throughout.

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!

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!
