What are the twelve grapes eaten in Spain at midnight on New Year's Eve meant to represent?

In Spain, the twelve grapes eaten at midnight on New Year's Eve represent the twelve months of the coming year.

The custom is called las doce uvas de la suerte, or “the twelve lucky grapes.” Participants try to eat one grape with each of the clock's twelve midnight chimes. Finishing the sequence is traditionally associated with good luck and prosperity for the year ahead.

Madrid's Puerta del Sol is the most famous public setting for the ritual, and national television broadcasts the clock chimes from there. Families and groups across Spain follow the timing at home, often preparing peeled or small seedless grapes to make the challenge easier.

The practice is frequently linked to a large grape harvest in 1909, when growers promoted grapes as a festive New Year's food. Earlier evidence suggests the custom existed before that campaign, so the harvest story explains its popularization rather than necessarily its beginning.
