Madrid has the famous Puerta del Sol countdown where people eat 12 grapes at midnight.
The celebration centers on the clock at the Real Casa de Correos in Puerta del Sol, a major square in central Madrid. As the clock strikes the twelve midnight chimes, participants try to eat one grape with each chime. The twelve grapes represent the twelve months of the coming year.
Spanish television broadcasts the clock chimes nationwide, allowing people to follow the ritual from homes and public gatherings. The custom is widely known as las doce uvas de la suerte, or the twelve grapes of luck.
The tradition is often linked to a surplus grape harvest in the early twentieth century, though earlier elite grape-eating customs may also have influenced it. The twelve chimes are preceded by warning sounds, so participants must wait for the actual midnight strokes.
