The designation draws its name from the largest town in the area, known for its hovering 14th-Century castle, the Castillo de Almansa. It was the frontier territory between the Moorish and Christian kingdoms of Aragon and Castilla. The climate is continental with long, hot summers and cold winters, with sparse rainfall. The stony and limy soils retain water and the altitude (900m above sea level) mitigates the hot summer sunshine. This area favors red grapes and has been farmed viticulturally since the 16th century.
