Aitaren is a family-owned winery located in Zestoa, in the Basque Country, near the coastal town of Zumaia. It specialises in producing txakoli, a traditional Basque white wine, under the Getariako Txakolina Designation of Origin. The winery focuses on expressing the character of its local landscape through wines made from its own vineyards, combining traditional craftsmanship with modern winemaking techniques.

The winery cultivates approximately four hectares of vineyards, mainly growing the indigenous Hondarrabi Zuri grape variety. Located around 1.5 kilometres from the sea, the vineyards benefit from the maritime climate and distinctive soils rich in clay, marl and minerals. The grapes are harvested by hand in small boxes and carefully selected to preserve their freshness and quality. During production, gravity is used to move the grape juice gently, avoiding pumps and minimising handling. Fermentation and ageing take place in different vessels, including stainless steel tanks, French oak barrels and concrete eggs, depending on the wine.

Founded in 2015, Aitaren continues the legacy of Juan Eizagirre, whose passion for winemaking inspired his children to establish the winery. Its name means “of our father” in Basque, reflecting its family heritage.
