On tap to a tulip glass. Golden amber in color, with a nice rich head. Some traces of lacing. Smell is not over the top, but I'm getting some hints of citrus for sure. Taste is awesome. Mellows as it warms up, fantastic citrus and grapefruit pop. Really love the aftertaste of grapefruit. It adds something different for sure. Mouthfeel is on point. Nice resinous coating on the tongue. Overall, different but very enjoyable. Try it!

A - Pours a hazy amber with a full white foam head.

S - grapefruit, pine needles, some citrus.

T - Bitter grapefruit and pine are straight forward. Some malt and hop notes as well.

M - Medium to low carbonation. Velvety and some mild thickness noted; though still balanced.

O - As grapefruit style hop flavor is my preference I may enjoy this more so than usual.
Worth another tasting.

Poured a golden body with two finger head and lace patches all down glass. The aroma is mostly hoppy and bitter but there are detectable notes of "grape" hops in there. I find the beer to mostly bitter and dry, the hops are a tad oily and earthy but there are grape notes to be found in this beer and it is rather light bodied and easy to drink. At times, even, I found the grape tastes to give off a touch of sweetness. Not the most flavorful or complex ale but it hit the spot.

Though I don't have any data or anything to back this up, I always thought that grapefruit-heavy IPAs were a midwest thing. A big, fat, white guy thing, to be specific. We don't care about balance. We want something extreme. The aroma's got to be enough to overpower the fumes of the nacho cheese sauce that's usually clinging to our neckbeards. It also must get us drunk enough so that we forget about the hideousness of our wives.

So, hey, what's the late-sipping, muslim-kissing taxlovers over in California got to say about hideously unbalanced grapefruit flavored IPAs?

This is a pretty good iteration, actually. The aroma is intentionally unbalanced, and the hops are equal parts green and tart citrus. Tastes the same, but with a little bit of crackeriness on the very back end makes it tastes like beer, as opposed to hop tea.

look: 4.25 | smell: 3.75 | taste: 3.5 | feel: 3 | overall: 3

Had this one at Alewife in Baltimore. From notes.

A - Nice golden pour with mild carbonation. Bright. Two fingers of dense, fluffy white head left great lace rings and a film of retention.

S - Grapefruity citrus notes. Something also reminded me of grapefruit seeds.

T - Lot's of pith. Grapefruit very obvious, sweet fruits.

M - Pithy bitterness was strong with a medium body and medium carbonation. The bitterness wasn't my style.

O/D - Not a bad beer, but not my thing. The grapefruit element was just far too strong and I couldn't really get past it. Not a flaw, just not my scene.

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.

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.

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.

Enjoyed on tap at Bier Station as I await the tapping of a firkin of Odell's Tree Shaker. Guess it's gonna be a fruity IIPA type of night. Poured into a small Belgian tulip glass.

Appearance - Pours a bright copper-orange hue with hints of darker shades based on how the light passes through. Almost red clay colored in spots. Atop the body sits a towering three-finger frothy head that looks more like pie meringue than it does beer foam. Just a few larger bubbles sit in the center of the foam on top from where the pour entered the glass, but otherwise, the head consists of bubbles so fine that it looks like a uniform off-white mass at a glance. Retention is excellent and leaves ample lacing as I drink it down.

Smell - The beer is aptly named. Yes, it is full of grapefruit and yes, there is so much that it feels like a slam. Big citrus notes are present, with hints of fresh-squeezed orange and lemon peel, but make no mistake: grapefruit juice is the overwhelming characteristic. It reminds me a lot of a grapefruit mimosa in the aroma. Very hard to detect much in the way of the malt backbone at all.

Taste - The aroma is a perfect herald for the taste that follows. There is so much grapefruit here that I feel like I can detect the different types of grapefruit. Sweetness, like red/pink grapefruit, and an arresting bitterness, as is common with white grapefruit. There are also some more herbal, piney elements to compliment the dominant grapefruit and keep it from getting out of hand. After all, if we wanted only grapefruit, we'd just drink the juice, amirite? Here I do get a little bit of water cracker and light grain to balance out the hop wallop, but the lupulin is the ringleader here.

Mouthfeel - Medium body and moderate to high carbonation. Finish carries a significant amount of bitterness that lingers.

Overall, I must admit to being skeptical coming into this beer. So much so that I refused to buy a bomber. I've been burned by beers that derive grapefruit characteristics from the fruit/juice itself rather than the hops that often impart that sensation in the past. However, this one fully delivers on the promise. I just might have to go out and pick up a bomber now.

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.

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

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.

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

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.

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.

Among the most beautiful in a glass that I have ever seen. Not much in terms of a head, but of a color and clarity that I have never seen in a draft beer before. It practically sparkled in the glass.
The grapefruit was present, but not overpowering. I would use the same terms to describe the alcohol.
I hope they add this to their stable.

A Generous 16oz pour on tap @ WOB in Cherry Creek, CO

A – Bright, translucent orange, red hues around the edges, much more orange than I have seen in others of the style. Head is tall and off white, lacing left behind is sticky and clings nicely.

S – Fresh, tart grapefruit notes, really nice citrus tones here, not overly sweet, the citrus tones are fresh and tart. Little bit of pine comes through as well.

T – Fresh juice notes, grapefruit, clementine. Quite resinous and dry, more reminiscent of the rind and pith of the citrus rather than the flesh. Nice and complex, some balancing notes of pine as well.

M – Medium-Full body, quite dry and tart which is nice, this is no where near cloying which I feared it may be. Great bitter and drying finish.

O – Saw grapefruit slam on the menu and had to have it, this is a great IIPA, the citrus notes are out of the norm for the style, truly a great beer here. I had absolutely no clue Stone was behind this until I came on BA to look 'er up.

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.

4.2/5  rDev +4.7%
look: 4 | smell: 3.5 | taste: 4.5 | feel: 4.25 | overall: 4.25

A - Pours a light medium amber orange gold color (lighting isn't so good where I'm at rt now). Massive amounts of carbonation initially before equalizing after a few minutes to a steady trail of small bubbles. Thin white lacing ring.

S - Once again (as my previous review), a cold serving temp is masking the aromatic goodness. The majority of the aroma is coming from a spicy grapefruit resin.

T - Taste more than makes up for the lack of nose. MASSIVE amounts of spicy tropical rind: grapefruit, oranges/tangerines, passion fruit, guava, lemons, and some floral character in the background.

M - Thick medium texture that's borderline full body. The combination of tropical fruit leaves a metallic-like coating in the mouth.

O - Very well done, another impressive and superbly solid IPA from Stone.

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!

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.

On draught into a goblet, thin lingering head and lots of sticky lacing. Golden honey color.

Slight smell of citrus hops and grapefruit, not overpowering but it's there.

Lots of hop and grapefruit Flavors here, a real citrus bomb with not much malt to balance it out but good. Lingering bitterness.

Not real heavy, moderate carbonation.

Overall, great IPA, heavy on the grapefruit. I appreciate what it is, and it is good but not one of my faves.

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.

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.

At Gainesville HOB. Golden pour with creamy white head and lots of lacing. Smells like Ruination with some extra fruit sweetness. Flavor is big hoppy bitter as with regular Ruination, but lots of extra puckering grapefruit juice and acidity. Slick mouthfeel. This is a nice, albeit lighter variation, of the Ruination brand. More bitter and puckering with a highlight to the citrus. Good stuff.
