Haro Wine Festival is organized in the town of Haro located in the northern Spanish region of La Roja. The festival is held on the San Pedro (Saint Peter) day, the 29th June. The highlight of this festival is so called Batalla de Vino (Battle of Wine).
Everything starts at 7.00 a.m. with a procession involving locals wearing white shirts and red scarves. Everyone carries jugs and similar containers full of wine. The procession is lead by the town's mayor riding a horse.
As soon as everyone arrives at the Cliffs of Bilibio a mass is celebrated. After the mass there is a famous battle. Everyone tosses wine on each other. People get soaked from head to toe. At noon the celebration continues at the Plaza de la Paz (Square of Peace).
