The Cámbrico vineyards are located on the granitic terraces of the mountainous Sierra de Francia Natural Park, a UNESCO Biosphere Reserve in Salamanca, western Spain. The region has been home to vineyards for centuries, though 85% are now abandoned, due to depopulation and the difficulty of cultivating the mountainous landscape. In 2000, the founders of Cámbrico purchased 130 small plots of abandoned vineyards, saving many old vines, some up to 110 years old. The winery is devoted to preserving the natural ecosystem of this beautiful place. They not only follow strict organic growing practices but also encourage and revel in the flora and fauna that live in and around their vineyards. The native flora includes their vines, as they grow only native varietals, including Rufete and Tempranillo. The vineyards are planted on centuries-old mountainside plots, at elevations of 2,300-2,625 feet and are plowed by horse and harvested by hand.
