Every year on March 19 the txakoli wineries of Bakio present the previous year’s vintage to the public. A celebrity is in charge of opening up the first bottle of the prized wine, which carries the Denominación de Origen Bizkaiko Txakolina mark of quality control. Some of the other better-known products in the region, such as cheese, bread, lamb, and pastel vasco (Basque cake) will also be on sale. Several stands are also dedicated to crafts and basket making. The public can also view different types of animals, including pigs, goats, oxen, sheep, cows, a breed of Basque horse known as pottoka, and dogs. Sports activities are also a mainstay of the San José fair. Bakio will host the pala championship (a version of Basque pelota which uses a bat) and an exhibition of herri-kirolak (rural Basque sports), which will include the event that will determine the winner of the San Jose gold medal for stone-dragging by oxen.
