Sustainability is central to the Eguren family. The vineyards have been cultivated according to organic viticultural principles for over thirty years. Chemical pesticides have therefore not been used for a long time. The vineyards of Sierra Cantabria are protected from the cold northern winds by the Sierra Cantabria mountain range of the same name. The vineyard locations differ from each other in altitude, soil composition, location and age of the vines. They all benefit from the confluence of Atlantic and Mediterranean climate influences. Each vineyard therefore has its own character and it is these different character (terroir) properties that the Eguren family wants to reflect in the wines.
