I believe this is just the regular Green Blaze with some grapefruit juice added. Still hazy, perhaps a light ruby tint from the grapefruit. Smells of juicy grapefruit and citrusy hops, malt is deeply hidden. Tastes of juicy citrus and dry, crackery malt, low hop bitterness comes in to back it up. Full mouthfeel leads to a distinctly grapefruit flavored finish, with a light, spicy hop overtone. Good use of the grapefruit flavor.
