Madrid hosts the famous Puerta del Sol tradition of eating 12 grapes at midnight on New Year's Eve.
At midnight, people try to eat one grape with each of the twelve chimes from the clock at the Real Casa de Correos. The grapes symbolize the twelve months ahead, and finishing them in rhythm is widely associated with good fortune for the coming year.
The custom became nationally famous in Spain through newspaper coverage and the spread of the clock chimes by radio and television. Madrid's Puerta del Sol became its best-known public setting, although families across Spain follow the tradition at home.
The grapes are not simply eaten at any point during the countdown: participants wait for the twelve main midnight strokes. The preceding warning sounds from the clock are part of the broadcast sequence but are not themselves counted as the twelve grape chimes.
