What is the name of Spain's New Year's Eve tradition of eating 12 grapes with the 12 midnight clock chimes?

Las doce uvas de la suerte is Spain's tradition of eating 12 grapes with the 12 midnight clock chimes.

The Spanish phrase means “the twelve grapes of luck.” Participants try to eat one grape for each stroke of the clock at midnight on December 31. Completing the sequence is popularly associated with good fortune for the twelve months ahead.

The best-known public countdown is broadcast from Madrid’s Puerta del Sol, where the clock of the Real Casa de Correos provides the chimes. Families and friends commonly follow the countdown at home, often using prepared tins or small packs of twelve grapes.

The custom is sometimes described as beginning with a single official decree, but historical accounts connect its spread to grape surpluses and promotional efforts around the start of the twentieth century. The exact origin story is therefore less certain than the modern practice itself.
