Txomin Etxaniz is a family estate in Getaria on the Basque coast of Gipuzkoa, run by the Txueka-Etxaniz family, who trace winegrowing near the town to a 1649 reference to Domingo de Etxaniz. The estate works the indigenous Hondarrabi Zuri and Hondarrabi Beltza varieties in vineyards set close to the Atlantic, where high rainfall and maritime exposure shape the local txakoli tradition.
The family was central to the modern revival of the region's wine: Iñaki Txueka led the movement, begun around 1980, to organize Getaria's growers, and the estate was a founding force behind the Getariako Txakolina denominación de origen established in 1989. Alongside its standard estate txakoli and a rosado, the estate produces the single-variety TX cuvée bottled under the Getariako Txakolina D.O. and labelled as estate-bottled (embotellado en la propiedad).
