3.73/5  rDev -7%
look: 3.75 | smell: 3.5 | taste: 3.75 | feel: 4 | overall: 3.75

Poured from a 22 oz brown bomber into a clear glass snifter. Bottled on 1/30/14 on bottleneck. Purchased at Wine Warehouse (Charlottesville, VA).

A: Fruity orange with solid 1-finger white head with decent retention and a solid smattering of lacing.

S: Muted citrus grapefruit aroma, more like the peel and pith than the meat, with floral and honeysuckle hops notes but a stronger than expected medium caramel malt contribution. No yeast or alcohol contributions.

T: The flavor is also surprisingly strong on caramel malt character, usually not an issue for Stone beers. The hopping/fruiting is heavy on grapefruit citrus but doesn't quite hit the highly bitter level, and the pithy nature of the flavor increases the vegetative side and misses out on the fruity side. There is no yeast or alcohol notes. Bitterness is moderate to high.

M: Very easy to drink despite the high bitterness. Body is medium with medium carbonation. Low-to-no alcohol feature also helps.

O: Good beer but not up to the level of Enjoy By or most top-tier DIPAs by a long shot. I know that it is not supposed to be the same, but they are not really even close. The pithy nature of the grapefruit ups the bitterness with really little to no flavor benefit. One and done for me.

3.79/5  rDev -5.5%
look: 4 | smell: 3.75 | taste: 3.75 | feel: 4 | overall: 3.75

Poured from a bomber in a tulip.

A- Nice pour. No shortage of pale cream head. Nice amber orange color with some light distortion. Good looking beer and leaves nice lacing.

S- Heavy fruit up front. Almost like a tropical citrus fruity pebble mess. Very sweet nose. Mellows out after a while to give a nice sweet grapefruit and peach aroma. I like this better as it warms.

T- Almost like a heady... but the pieces just don't come together. The sweet, bitter citrus from the hops and the malt clash with the alcohol content which isn't overwhelming. It's topped off with a decent amount of bitterness toward the end. I just think there could have been a much better balance to this one. Tasty but it hasn't reached it's potential.

M- Nice carbonation even after it warms. Medium mouthfeel and leaves you a bit dry and bitter.

O- A decent offering from Stone. I especially like the peach/grapefruit nose and taste. The balance is just off though. Recommend if you like a lasting bitter citrus IPA.

3.95/5  rDev -1.5%
look: 4 | smell: 4 | taste: 4 | feel: 3.5 | overall: 4

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.

3.95/5  rDev -1.5%
look: 4 | smell: 4 | taste: 4 | feel: 4 | overall: 3.75

Bomber poured into a large wine glass after sampling a few times on draught. Pour is clear and deep golden in color and offers a decent cap of off white foam. Shows good retention and spotty lace throughout.

Fragrent hop aromas dominate the nose with citrus and a bit of tropical fruit. There is definitive grapefruit there as well and more pronounced that on the tap version. Touch of alcohol on the nose with warming along with even more vibrant hop aromas.

More grapefruit on the taste along with a light caramel influence and some lemony coarse malt texture and a light hint of grapefruit juice. Bitterness appears somewhat subdued but the coarse malt texture offers a lingering finish and keeps the body full. Nice and clean delivery, well balance yet in your face in a Stone kind of way.

4.13/5  rDev +3%
look: 4 | smell: 4.25 | taste: 4 | feel: 4.25 | overall: 4.25

22 oz. bottle poured into a Burley Oak snifter

A: Golden yellow tinged throughout with copper. Very little lacing and a small, rapidly dissipating head. Even with a swirl you get very little head.

S: Tons of citrus, predominately grapefruit. Nearly all of the hops are fruity. There is just a whisp of the sweet, deep malt backbone holding all of these flavors up.

T: Lots of hops but the malt bill is really making itself known. Lots of grapefruit, as expected with the sweetness of the malts. Great aftertaste but not as sticky as some of them (like last night's Flying Dog Single Hop Amarillo).

M: Nice carbonation that is pretty even throughout with lots of coarseness.

O: I kept waiting to open this because I didn't want to drink it by itself, but here I am drinking it by myself.

3.78/5  rDev -5.7%
look: 4.25 | smell: 3.5 | taste: 3.75 | feel: 4.25 | overall: 3.75

Poured Stochasticity Project Grapefruit Slam IPA into a Belgian Tulip.

A - Pours a hazy dark golden with a full finger of off white head.

S - Subtle notes of grapefruit, pine needles, some malt in there as well.

T - Not too bad. You can notice more tangy grapefruit initially. It has some dankness followed by the balance of malt mid palate. On the aftertaste more raw grapefruit with hops. Its not too bad.

M - Love the mouthfeel. Medium to low carbonation. Medium to full mouthfeel.

O - I think I'll stick with the other Stone's IPA's. Cheers!

3.19/5  rDev -20.4%
look: 3.75 | smell: 3 | taste: 3 | feel: 3.5 | overall: 3.5

Poured from a bomber into a goblet.

A: Almost clear, light amber color with one finger of diminishing white foam head. Moderate lacing remains on the glass.

S: Faint overall, with biscuit and floral qualities. No yeast metabolite influences are detectable, nor is any alcohol.

T: Begins off-dry, with simplistic piney and lemon peel hops aromatics and refined pale malt. Acidity is high into the middle where precocious bitterness rapidly replaces aromatic flavors. The finish is piney-herbal and strongly bitter. No alcohol is detected.

M: Medium to thick viscosity, resinous and slightly acidic on the palate, with moderate carbonation.

D/O: This IPA is a tame contribution to the style, positioned deep in the second tier of recipes despite its inclusion of grapefruit citrus fruit. The actual citrus fruit is practically undetectable in the final product, which is malty and unafffected with a hops profile seemingly borrowed from a decade ago. Other than its relatively high gravity (technically a double IPA, although it does not drink as one) it is indistinguishable from something generic like a New Belgium Ranger IPA. Despite relatively potent bitterness, this beer is an easy drinker.

4/5  rDev -0.2%
look: 4 | smell: 4 | taste: 4 | feel: 4 | overall: 4

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.

A: Pale with nice creamy head that lingers a bit. Some haze

S: Strong grapefruit peel on the front end followed by some pine. Slight dankness.

T: Bitterness from the grapefruit peel upfront, nice and dry finish. Some caramel bread notes as well.

M: Medium in body, nicely dry.

O: Not a bad beer, was expecting more out of the flavor but solid.

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

Appearance - The beer was a golden copper color with a modest white head and lacing surrounding the sides of the glass.

Smell - As a whole, it smells like a regular IPA. I detect notes of fresh grapefruit, but not enough to tell me this IPA is much different than others.

Taste - At the initial taste, there is a faint tea-like sensation. Then, the grapefruit comes through. It starts with the bitterness of the rind before becoming progressively more sweet. In the aftertaste, the bitter resin sticks to the roof of the mouth. In some aspects, I think the finish is somewhat dry.

Mouthfeel - The taste clings to the mouth and tongue, so there is some thickness. The carbonation seems to be very appropriate.

Overall - This is a quality IPA, but I do not think it is exceptional. The grapefruit does not add a great deal of depth. Try it, just to say you had it. However, I do not think most drinkers will feel the need to stock up.

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.

4.35/5  rDev +8.5%
look: 4.5 | smell: 4 | taste: 4.5 | feel: 4.5 | overall: 4.25

Poured into a pint glass out of a 22oz bomber.

Pours a slighty hazy medium orange with a billowy two finger white head. Amazing head retention and even better lacing with a near solid ring all the way around the glass most of the way down.

The grapefruit sure makes its presence known in the aroma. Awesome hop notes with the Centennial especially evident. Some nice earthy notes in there too adding a bit of balance.

The flavor closely follows the aroma with tons of grapefruit along with orange peel and a bit of earthiness. A fairly nice malt balance although it remains well in the background. Bitterness is very high but it works quite well in this beer. The alcohol is completely hidden and a fairly dry mouthfeel gives this incredible drinkability.

Overall, as usual Stone does an amazing job with this IIPA. Everything is in balance and the flavor are outstanding. An amazing IIPA that everyone who loves hops should experience.

22oz bottle dated 1/29/14.

Pours clear copper with a thin, white head once settled. Dotted lacing for the duration.

Aromatics are chock full of pungent pine and grapefruit. Some boozy alcohol wafts through.

Medium bodied with a tacky, resinous mouthfeel.

A palate-numbing assault of grapefruit pith and bitter pine sap flavors lay down the gauntlet.
Lingering bitter hops follow through with barely a trace of malt.

Finishes with grapefruit and pine.

Ruination on grapefruit steroids. Nice.

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

Transparent amber color with a finger of fluffy white head that retains for days. This is a beer you can smell from a couple feet away -- the grapefruit is definitely there but I also get some tangerine, orange, lime, and sweet malt. The taste is super bitter all the way down with strong notes of grapefruit peel and lemon peel, a dry malt backbone, hop resin, and some sweeter tropical citrus to provide the only semblance of balance. This is a massively bitter beer, but I can't knock it since its main selling point is that it's brewed with grapefruit peels. It succeeds at what it set out to do.

A well done IPA with a crisp flavor and nice citrus from the grapefruit. Everything about it is what you'd expect from a good IPA, but nothing stood out to make it legendary. Glad I got a hold of this one; however, I won't be purchasing again. It was a one and done beer for me.

Bottle poured into a tulip

A - A pretty orange color with a one finger head. Crystal clear but very active carbonation

S - Grapefruit with a touch of sweet malt in the background. A little muted.

T - A full grapefruit assault on your palate. Super hoppy.

M - Palate wrecker for sure. Very dry finish, a touch oily, and very bitter.

O - Very harsh on the finish and excessively bitter. If it was toned down a bit, it would be more drinkable.

Bottle share at Proof done side-by-side with Proof's Guru IPA blended with Apollo aged on grapefruit. Pale straw in color with very little head. Big grapefruit and orange citrus with some tropical fruit in the aroma. Taste is spicy/citrus combo with a fair malt backbone. High carbonation (despite little head) and medium body. I enjoyed the Proof considerably more.

General: This was purchased at a BevMo in the inland empire. I've heard good things about this beer but never tried it. I poured this into a Bottle Logic "lab glass" for tasting.

Appearance: Big off white head that's more like a foam, it's a lot of little tiny bubbles with a couple of larger bubbles spaced out in between them. Color is a beautiful gold, a touch on the darker side of the gold spectrum but not much.

Aroma: This is a really pine, grapefruit scented beer. Very nice. There is a nice little backbone of malt to the aroma for sure.

Mouthfeel: This is very drying, carbonation is pretty good. It's got the right mouthfeel for a DIPA.

Taste: Grapefruit and pine and resin are the primary flavors. This has a slight maltiness for balance but this is a big hoppy beer.

Overall: This is a pretty good DIPA, I like the flavors. There are a lot of other beers that are out there that taste the same. Everyone is going for a big citrus DIPA beers and this one may just get lost in the mix. It's good, not exceptional, but solid.

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

Poured a clear reddish-copper color in a tulip- my choice glass for a DIPA with a 1/2F head.
Carbonation bubbles from the bottom of the glass.

A different type of grapefruit aroma from the glass: lighter and sweeter than any other DIPA I have tasted. Not conventional nor over-the- top aroma. Pleasant and complementing the MF-taste-finish of the beer.

Mouth feel- as expected- very carbonated. 95 IBUs in this beer.

Taste: Extraordinary. I have never tasted so much grapefruit in a beer. In addition to the hops, there are grapefruit peels added to the mix. It's almost like drinking grapefruit juice itself:)

Finish- very hoppy with a light bitterness.

In general- a very different beer, and a must try for Stone fans.

3.96/5  rDev -1.2%
look: 3.75 | smell: 4 | taste: 4 | feel: 3.75 | overall: 4

Poured from the bomber into a tulip. Appears a nice orange color with a good white head, that doesn't stick around forever, but leaves a bubbly ring around the edge of the glass, as well as some great lacing.

The nose is very citrusy and floral, with a touch of caramel sweetness. The grapefruit is definitely present, but not as forward as I would expect.Just a bit too muted for me. The taste is very bitter, with tons of citrus up front. That bitter grapefruit really comes through in the finish here, and the lingering aftertaste is that flavor. The sweetness is almost non-existent here.

The mouthfeel is medium bodied, with a slight stickiness, but not too much. The carbonation is at a good, average level, but active enough to pull everything together. Overall, this is a good DIPA, but nothing that blew me away. The name is fairly appropriate, with lots of grapefruit presence, but I don't know about the "Slam" part. In the end, something worth trying, but didn't blow me away.

From a bottle into a tulip glass

Nice golden color with a good fruity smell. That's where the fun ends. The taste is nothing but grapefruit pithy peel. I don't get anything but bitterness from the rind. I barely even get any hoppy flavor. Pretty unimpressed. Nicely carbonated. Just wish it would have been more balanced with grapefruit peel and hops. Its very one-sided. Won't visit again.

look: 4.5 | smell: 4 | taste: 3.5 | feel: 4.5 | overall: 4

A-Pour is a slightly hazy yellow gold. Large frothy white head has good retention and spotty lacing.

S-Opens with a large blast of citrusy hop notes, lemon and grapefruit. Malt notes are very light with hints of biscuit. No esters, no alcohol, no DMS. Bitter citrus rind notes persist.

T-Hops take the forefront, as expected. Hop flavor is moderately high, with lots of grapefruit along with some resiny background notes and some pine. Hop bitterness is very high with a bitterness that is long lasting. Malt backbone is solid but understated. Balanced toward the bitterness for sure. Warming alcohol is present at a medium high level, and detracts a bit from the finish.

M-Medium bodied to medium full. Carbonation is medium. Not astringent. No creaminess.

O-Overall a very nice beer. The hop aromas and flavors are the standout. I'd prefer a slightly lower hop bitterness as it lingers long into the finish. A bit less noticeable alcohol would be welcome as well.
