Ribera del Guadiana is a Spanish Denominación de Origen (DO) for wines located in the region of Extremadura (Spain). It extends over two provinces, Cáceres in the north and Badajoz in the south. It takes its name from the River Guadiana, which flows through the region from east to west.

History
The region was officially created in 1999 by combining the six sub-zones that up till then had produced Vino de la Tierra, a lower quality of wine on the Spanish quality scale.
Sub-zones
The DO is divided into 6 sub-zones, of which Tierra de Barros is the largest, comprising 80% of the vines.
Tierra de Barros
The Tierra de Barros sub-zone covers 36 municipalities. The soil is clayey with very good moisture retention properties and has a high lime content. The lie of the land is flat which allowed the mechanization of vineyards activities.
Cañamero
The Cañamero sub-zone covers 5 municipalities in the Sierra de Guadalupe range to the east of the province of Cáceres at an altitude of over 800 m above sea level. The vines are planted on slopes on poor soil over a slate stratum.
Montánchez
The Montánchez sub-zone covers 27 municipalities to the south of Cáceres. The land comprises hills and valleys, with rich, brown, slightly acidic soil at an altitude of about 625 m above sea level.
Ribera Baja
The Ribera Baja sub-zone to the west covers 11 municipalities and reaches to the Portuguese frontier. The soils are clayey and alluvial at a low altitude of about 250 m above sea level.
Ribera Alta
The Ribera Alta sub-zone to the east covers 38 municipalities at an altitude of about 400 m. The soils are sandy and not very deep.
Matanegra
The Matanegra sub-zone is further to the south covering 8 municipalities. The soils are similar to those in Tierra de Barros, while the climate is cooler due to the higher altitude of over 600 m above sea level.
Climate
Extremadura has a continental climate: hot dry summers when temperatures can reach 40 °C, and cold winters when they can drop to 0 °C.
Rainfall varies according to the sub-zone in question, and can be considerable in the mountainous areas, such as Cañamero. The average rainfall is 450 mm/year. The main challenges faced by the grape growers is drought in summer and frosts in spring.
Grapes
29 different grape varieties are authorized by the DO Regulatory Council, some of which are native to the area and are unknown in the rest of Spain. Tempranillo is the most widely planted variety (14,500 ha out of a total of 25,000 ha covered by the DO).
