Iñaki and Rosa María Exteberría have always run the family’s dairy farm, but in 2001 they planted 4 hectares of Hondarribi Zuri, Petit Corbu, and Gros Manseng, and started making Txacolí. Having their vineyards inland – as opposed to the majority of producers who have them right by the sea – meant that they fell outside the official appellation area, and Iñaki and Rosa María fought an arduous battle to have their wines recognized under the DO status.

Nowadays they work their vineyards organically and produce a style of wine quite distinct from the light and sparkly examples found in San Sebastián.
