Founded in 1957 by Guillermo Eguren, Sierra Cantabria is nestled in the heart of San Vicente de la Sonsierra, a town of great winemaking tradition, situated in a unique location between the River Ebro and the Sierra Cantabria mountain range.

The Sierra Cantabria mountain range (1,200 m. of altitude) and the river Ebro (350 m.), create a special microclimate with Mediterranean and Continental characteristics -providing mild winters and gentle summers- unique for vine cultivation.

On the other hand, the summer thermal jump (intense heat during the day with fresh night temperatures) creates an increase in the level of polyphenols, normally associated with excellent quality wines.
