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.

We pop a bottle labeled under Stone/Koochen Vagner’s “Stochasticity Project” heading, pouring a brew of dingy, dusky orange into our Founders snifters. It produces a commanding three finger head of soapy, thinned eggshell colored bubbles, showing excellent retention. Asymmetric cords and specks of lacing adorn the glasses circumferentially. No haze or sediment is noted whatsoever, and carbonation appears to be nearly nonexistent. The nose speaks of sugary sweet grapefruity and nectary hops, mango, white grape, and strawberry fruitiness, cloven and plastic phenols, pale, amber, and chalky crystal maltiness, lemon and orange rind, cloying cotton candy sweetness, lemon tea tannins, fusel booziness, mustard seed and black pepper, massive bubblegum esters, tight vinegar sugars, and zucchini and celery vegetals. Our first impression is that it is much more bitter than the taste would let on, however, the included grapefruit rind, adds an intensity that would not otherwise be garnered from the hop bill alone. As we sip, the flavoring opens with pith and oily skinned zest of authentic grapefruit and orange fruitiness, continued massive bubblegum aromatics, soured orange juiciness, white sugar, fermented strawberries, chemical lemon cleaner, black pepper and clovey spice, phenolic plastics, and black cherry flesh. The middle hits with sweetness, contained within white and confectioner’s sugars, soft citric, grassy, and floral hoppiness, clean pale and lightly roasted caramel maltiness, banana and bubblegum esters, tart tangerine juiciness, lemon zest, and wheatgrass. The end comes with the sweetest booze mixing with hearty hops of citrus, herb, and soap, green twiggy sap, clean orange rind bitters, cleansing soapiness, cardboard calmness, sweet potato starchiness, burnt molasses and toasty pales, cucumber freshness, tannic lemon teas, and finishing plastic bitterness. The aftertaste breathes of chalky pale malts, dry brown rice, chemical phenols and chlorine bite, piney and grapefruity hop bitterness, fresh curly leaf parsley, walnut and peanut shells, pencil lead, musk and dust, coiny metallics, ale yeastiness, and bitter vegetal tomato skinned acidity. The body is cleanly medium, and the carbonation is lightly medium. Cream, froth, slurp, and smack are all pleasant and wonderfully contributory, with finishing pop drawing hard to the upper lip. The mouth is initially foamed and coated, but this quickly thins to oily astringency and decently robust pucker. The abv is appropriate, and drinkability is high.

Overall, the most enjoyable thing about this beer is its flavoring. This was a hard sell when compared directly to the aroma, however, as that aspect of the brew was intense and inviting from beginning to end. The nose actually showed a surprisingly vast array of sweetness; the primary component of which was a stark, sticky, chewy bubblegum ester. This blended curiously with the heavy bitterness of the hops and the grapefruity inclusions, but made for a rather wonderful balance. This is a sweeter, much more approachable and commercially acceptable DIPA for the masses, coming from the west coast, and from Stone. That balanced sweetness will have a lot of appeal, as will the fresh fruitiness from the grapefruit skins. This should be an interesting series to follow, and hopefully they can maintain the potential hype of “specialty ingredients” with each new addition, and deliver on them fully and without hesitation.

22 oz bottle. Pours clear golden orange with a medium creamy white head that retains well and laces the glass.

The aroma is sugary bready malts and tropical fruit / grapefruit.

The flavor is a little sweet fruity bready malt followed by a pretty big resiny bitterness. The mouthfeel is medium bodied with light carbonation.

Overall, a nice IPA, but not as good as I thought it sounded.

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.

22oz brown bomber with a freshness date.

Stunningly tight and sticky lacing on top of this hazed out pale amber brew. Big bag of smashed grapefruits rush the nostrils, hints of alcohol and hops within. My palate is simply being abused by the onslaught of grapefruit and hops, the alcohol is clean and quite warming. Some light bready tones underneath but the finish is just more lingering grapefruit and hops.

Slam? This is a Smackdown, thanks Stone for this one and keeping things fun.
