The annual Global Warming Open -- a beer competition sponsored by the Brewing News -- is back.



The judged tasting, set up like the NCAA March Madness tournament, features 32 beers pitted against each other in rounds until a champion is declared. The final four and championship will be held July 22.



Two Ohio beers are entered this year: North High Grapefruit Walleye from Columbus and Great Lakes Steady Rollin' from Cleveland. (The Fat Head's brewpub in Portland, Ore., also entered Grapefruit Goggle Fogger.)
