Haro Wine Battle in Haro
Each 29 June, residents of Haro climb the Riscos de Bilibio cliffs outside town and spend about an hour dousing each other with red Rioja wine using wineskins, buckets, and sprayers, a custom tied to a historic land dispute with neighboring Miranda de Ebro, followed by bull-running and further festivities back in town.
Haro's Batalla del Vino takes place each 29 June, the feast of San Pedro, when residents and visitors climb the Riscos de Bilibio, limestone cliffs just outside town, carrying wineskins, buckets, and improvised sprayers filled with red Rioja wine, and spend roughly an hour deliberately drenching each other until everyone present is stained deep purple.
