Oktoberfest will open after the ceremonial keg-tapping by Munich Mayor when he inserts the tap into the first keg at noon on Saturday.

Strong, amber-colored Marzenbier is the traditional beer served at Oktoberfest in Munich, Germany. But it's now found only in the United States.

Oktoberfest is open. Mayor Dieter Reiter officially started Oktoberfest at noon Saturday when he inserted the tap into the first beer keg, signaling the 189th start of the festival. Thousands of beer lovers celebrated in the Munich fairground as the first to clink their mugs during the world’s largest folk festival.
