Stone Stochasticity Grapefruit Slam IPA
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.
The essential oils and the monoterpenoids like geraniol and citronellol that are found in hops often provide aromatic components that are described in professional sensory panels as "citrusy" and are reminiscent of the flavors of grapefruit, lemon, or lime. For that reason, the potential synergy of specific hop varieties with citrus fruit is something that brewers who research unique ingredients, and who focus on combining the brewing art with brewing science, have been experimenting with for a while.
This particular beer combines the lemony and piney aspects of the Centennial hop with the intensity provided by dry grapefruit peel, which is added as a dry hop along with the hops.
The brew is converted in the brewhouse using a temperature rest profile designed to accentuate dryness and fermentability. The resulting Real Degree of Fermentation is high, the attenuation limit is low, the residual dextrin content
