Every year on St. Pedro’s Feast Day in Haro – capital of northern Spain’s Rioja-producing region – thousands of thirsty locals, together with wine-loving tourists, climb a mountain and literally throw vino all over each other. Some tote water pistols loaded with wine. Others are armed with pump-action super-soakers or spray cans filled with wine. Meanwhile, traditionalists opt for gourds, buckets, bottles and even old boots! Rather than a common-or-garden feast day, locals refer to this messy event as La Batalla de Vino de Haro, or, quite simply, the “Wine Fight”. All of this happens on the day of the patron saint San Pedro, and the liquid madness starts the previous night on the evening of June 28th. As the proceedings unfold pretty much all of the townsfolk gather outside – from children to grandparents – and party the night away in Haro’s cobbled streets and jumping bars.
