A Philadelphia brewery is celebrating the season 4 finale of the AMC's "Walking Dead" with its own brain-flavored, blood-tinted beer.

Dock Street Brewing Company's head brewer Justin Low is a big fan of the hit TV show, which is set in a post-apocalyptic world where zombies reside and regularly eat humans. Low told ABC News he came up with the American Pale Stout along with brewery representative Sacha Certo-Ware, who suggested ingredients such as cranberries to give it its "bloody red hue" and wood-wire roasted goat brains (not human) which give it a certain "smokiness."

The beer will be available on tap from Sunday, March 30.
