The Denominación de Origen (DO) de Jumilla, delimited in 1966, straddles two provinces. 45% of the vineyards are located in the province of Murcia, while 55% are in the province of Albacete, in the south-east of Castilla la Mancha. The Jumilla terroir is characterized by its succession of valleys and plains created by the La Serrania mountain range which crosses the region from the sea to the central plateau called the Meseta.

It extends over 21,620 hectares of vineyards that produce 79,606 tons of grapes (2015) cultivated by more than 2,000 winegrowers at an altitude that varies between 400 and 900 meters in arid conditions. Despite this, the region's viticulture dates back to the Romans and has built a solid reputation for its dense but good quality wines. It must be said that the grape variety most often planted, the monastrell, which constitutes 80% of the grape variety, is much more adapted than the cencibel (tempranillo) to this arid region, with its continental climate and low rainfall (250 to 300 mm per year). But the soil contains a good proportion of limestone, which conserves humidity, and the altitude provides some relief from extreme weather conditions. The region also enjoys 3,000 hours of sunshine per year and temperatures can reach 42°C in summer and -5°C in winter. Occasional but potentially torrential rainfall and frost in the spring are additional risks for viticulture in this region.

Apart from Monastrell (Mourvèdre), there are recently planted Cabernet Sauvignon and Merlot which combine rather well with this grape variety as long as they remain minor components. For the whites, we still find airén, macabeu, pedro-ximenez and malvasia as well as some chardonnay. Jumilla is undoubtedly the most interesting DO of Castilla la Mancha and Murcia.
