The climate of Ribera del Duero is unique and ideally suited to growing quality red grapes. Mediterranean with Continental influences, the Ribera climate is characterized by extremes; the region has the highest average elevation in Europe for growing red wine grapes, hot summers, cold winters, a short growing season, minimal rainfall, and a diversity of soils.  Combined, these conditions favor the highest quality winemaking.

Summers are short and hot with temperatures ranging from 50 to 60 °F (10 to 15.5 °C) at night to over 100 °F (38 °C) during the day.  Rapid daily temperature changes during the growing season facilitate healthy ripening of the grapes by day, and promote balanced acidity and aromatic complexity at night.  Moderate to low rainfall, with an average of approximately sixteen inches per year, and extremely limited summer rainfall, also contributes to a perfect, consistent ripening of the vine.

On average, the vineyards of Ribera are planted between approximately 2,500 to 2,800 feet (760 to 850 meters) above sea level (with some vineyards as high as 3,100 feet or 945 meters), resulting in considerable differential between night and daytime temperatures.

Soil conditions in Ribera are near-perfect, with a great diversity of soils extending from the banks of the Duero to the steepest slopes.  Closest to the river, soils are alluvial with sand and reddish clay.  At higher elevations, alternating layers of limestone, marl and even chalk are a notable feature, even with many outstanding plantings on limestone sites.
