Dean Metropoulos is positioning himself to sell Pabst Brewing Co., maker of Pabst Blue Ribbon beer, which his investment company owns along with the recently revived Hostess snack-food empire.

All our hopes for limited-edition Twinkies with PBR-cream filling have officially been dashed. [Chicago Tribune, Earlier]
