Txakoli lovers know that the rain in Spain falls mainly on the Atlantic coast, and not on the plain. What they may not know is how close Txakoli's wine tradition came to disappearing entirely: phylloxera and oidium gutted Basque viticulture over a century ago, reducing it to a forgettable domestic novelty well into the 1980s, before San Sebastián's emergence as a world gastronomic capital restored its standing, first at home and then abroad. The Errasti family has been farming these slopes since the 1940s, and when Getariako Txakolina became the first official Txakoli designation in 1989 (the heartland of the tradition, as most producers and drinkers acknowledge), they were already there. Their 15 hectares occupy windy hillside sites above the Cantabrian Sea, including the only Txakoli vineyard within a natural park, farmed with biodynamic tendencies and vinified with minimal intervention in keeping with a house philosophy of improving the tradition rather than departing from it. The wines deliver exactly what the style promises, and then a little more.
