Spanish tradition says that wearing new, red underwear on New Year's Eve brings good luck. The actual countdown is primarily followed from the clock on top of the Casa de Correos building in Puerta del Sol Square in Madrid. It is traditional to eat twelve grapes, one on each chime of the clock. This tradition has its origins in 1909, when grape growers in Alicante thought of it as a way to cut down on the large production surplus they had had that year. Nowadays, the tradition is followed by almost every Spaniard, and the twelve grapes have become synonymous with the New Year. After the clock has finished striking twelve, people greet each other and toast with sparkling wine such as cava or champagne, or with cider.
After the family dinner and the grapes, many young people attend cotillones de nochevieja parties (named for the Spanish word cotillón, which refers to party supplies like confetti, party blowers, and party hats) at pubs, clubs, and similar places. Parties usually last until the next morning and range from small, personal celebrations at local bars to huge parties with guests numbering the thousands at hotel convention rooms. Early the next morning, party attendees usually gather to have the traditional winter breakfast of hot chocolate and fried pastry (chocolate con churros).
