Climate & Terroir
The Central Valley has a Mediterranean climate with warm, dry summers and cool, wet winters. Soils are largely alluvial—sands, silts and clay—with local granite and volcanic influences in some subregions. Vineyards sit on flat valley floors and gentle foothills, enabling irrigation from rivers fed by the Andes. The combination of reliable heat, long growing season and varied soils supports consistent ripening and a broad range of wine styles.
