Kirk Hammett along with Dark Matter Coffee, based in Chicago, is coming up with his own coffee blend, named Ghoul Screamer. According to the Dark Matter website:
Guarding a serpentine circuit of obsidian, Ghoul Screamer was forged in the bottomless mines of Az'g'orath to protect humanity from the forces of evil by summoning the scream of the Ghoul. (from "ghôùll", Sumarian for "sick tone"). Heed the prophecy; only warriors of the sacred caffeine-to-blood ratio will wield the power of Ghoul Screamer, a fully fermented brew with waves of untamed punch. Those unworthy will be consumed by its force.
Whew...That's intense. The coffee features notes of Apricot, Praline, and mulling Spice. Grab a bag now, it'd be the perfect gift for the coffee, and Metallica lover in your life.
