Sardon de Duero is a wine-growing area in northern Spain, to the west of Ribera del Duero. It is part of the prestigious 'Golden Mile' (La Milla de Oro) of wineries located along the Duero river in the autonomous community of Castilla y Leon. La Milla de Oro is said to have a special microclimate and is home to some of Spain's most renowned wineries, including Vega Sicilia, Dominio de Pingus and Bodegas Mauro. The area has an ancient winemaking tradition, established by the Romans, but Sardon de Duero's name has really only recently gained a reputation, despite not being an official appellation.
Sardon de Duero is home to the award-winning Abadia Retuerta winery, one of Spain's most high-tech producers. The company has been critical in raising the profile of the area and have encouraged other growers to establish themselves here. Abadia Retuerta is located in the grounds of a 12th-century monastery, Santa Maria de Atuerta, 20 miles (32km) southeast of the historic city of Valladolid. Its highly regarded red wines are classified as Vino de la Tierra.
