Black Sabbath has teamed up with Half Time and Knucklebonz to create the Iron Man Lager. The beer was brewed by Decadent Ales and is presumably available to everyone on the planet aside from Bruce Dickinson. The beer's product description reads as follows, and is available for pre-order here (depending on if you state allows beer to be shipped).
"Iron Man Lager, the first ever officially sanctioned Black Sabbath beer has traveled through time to save mankind from bland and flavorless beer. Produced by Knucklebonz in coordination with Black Sabbath and brewed by Decadent Ales, Iron Man Lager is a rich, full-flavored lager brewed with premium barley malt that gives it a slightly sweet, well-balanced taste. A light hop addition accentuates a crisp, clean finish.
