MUNICH (AP) — The beer is flowing at Munich's fabled Oktoberfest.

Mayor Christian Ude inserted the tap into the first keg Saturday with two blows of his hammer and the cry of "O'zapft is" — "It's tapped."

As tradition demands, he handed the first glass to Bavarian governor Horst Seehofer, who beat him in a state election last weekend.

This is the 180th edition of the Bavarian capital's annual celebration of beer, with beer tents spread over sprawling grounds close to downtown Munich.

Some 6 million visitors are expected by the time the festival ends on Oct. 6. Last year, 6.9 million liters (14.6 million pints) of beer were quaffed at the Oktoberfest.
