Four Ohio breweries -- Great Lakes, Platform, North High and Samuel Adams -- are entered in this year's Global Warming Open, a beer competition sponsored by The Brewing News.

The 11th annual competition pits beers against each other in a single-elimination bracket format until there is just one winner. It begins Friday, (June 15) with the champion being declared July 9.

This year, the Global Warming Open is broken into two brackets: "Most Refreshing" and "Hoppily Refreshing."

Great Lakes entered Burning River Pale Ale, Turntable Pils, Holy Moses Raspberry White Ale and Holy Moses White Ale. Platform entered Torrential Downpour Hazy IPA and Hyper Retro Lemon Ginger Saison, while North High submitted its Grapefruit Walleye.

Samuel Adams, which operates a brewery in Cincinnati, entered Hoppy Wheat, New England IPA, Porch Rocker and Raspberry Lemon Gose.

In a cruel twist for Ohio beer lovers, Turntable Pils faces off against Torrential Downpour in the first round.

Beer fans can play along and attempt to predict the winners -- just as you would for the NCAA March Madness basketball tournament. The top prize is a case of the champion beer.

Last year's winner was Florida Avenue Cucumber Berliner Weisse.
