Ribera del Duero is a Spanish Denomination de Origen (DO) located in the country's northern plateau and is one of eleven 'quality wine' regions within the autonomous community of Castile and León. It is also one of several recognized wine-producing regions to be found along the course of the Duero river.
The region is characterized by a largely flat, rocky terrain and is centred on the town of Aranda de Duero, although the most famous vineyards surround Peñafiel and Roa de Duero to the west, where the regional regulatory council or Consejo Regulator for the denomination is based.
Ribera del Duero was named wine region of the year 2012 by the prestigious Wine Enthusiast Magazine.
Wine has been produced in the region for thousands of years, but viticulture as we know it probably arrived in the Ribera del Duero region with Benedictine monks from Cluny in the Burgundy region of France in the twelfth century.] Ribera del Duero wine making goes back over 2,000 years as evidenced by the 66-meter mosaic of Bacchus, the god of wine that was unearthed relatively recently at Baños de Valdearados.
The Denomination de Origen (D.O.) of Ribera del Duero was founded on July 21, 1982, by an organization of wine producers and growers who were determined to promote the quality of their wines and enforce regulatory standards.Reports that it was set to be upgraded to Denomination de Origen Calificada (DOCa) status in 2008 proved to be unfounded and, as at 2011, it remains a DO and has no plans to change
Ribero del Duero wines are currently enjoying greater popularity, thanks largely to the considerable interest shown in the area by experienced growers from other regions.
The Ribera del Duero is located on the extensive, elevated northern plateau of the Iberian Peninsula. It occupies the southern plains of the province of Burgos, extends west into Valladolid and includes parts of Segovia and Soria provinces to the south and east, respectively. As its name suggests, the region follows the course of the Duero river for approximately 115 km upstream from Valladolid and is around 35 km at its widest. The region is located around the younger stretches of the river, which later passes through the nearby Toro and Rueda regions before traversing the famous Portuguese growing areas of Douro and Porto, where it drains into the Atlantic Ocean.
Geologically, tertiary sediments, consisting of gently lenticular layers of silty or clayey sand, alternate with layers of limestone, marl and chalky concretions. The Duero valley, formed during the Miocene period, has a flat, rocky, gently undulating terrain, ranging from 911 m down to 750 m above sea level. The national highway N122 follows the river valley.
The Ribera del Duero has moderate to low rainfall (450 mm per year) and is exposed to quite extreme climatic conditions; long, dry summers with temperatures of up to 40 °C are followed by hard winters during which temperatures may fall as low as -18 °C. There are also marked variations in temperature within each season. The climate is continental and Mediterranean, with more than 2,400 hours of annual sunlight.
Vineyards occupy around 120 km² of the region, most of which are situated in the province of Burgos, with around 5 km² in Valladolid and 6 km² in Soria.
Wines produced in the Ribera del Duero DO derive almost exclusively from red grapes. The Albillo grape is the only white variety grown, white wines being mostly destined for local consumption. The vast majority of production is dedicated to Tinto Fino (the local name for Tempranillo), the dominant red varietal in the northern half of the Spanish peninsula. Tinto Fino is often, but not always complemented with Cabernet Sauvignon, Malbec and Merlot, although the famous Tinto Pesquera, grown by Alejandro Fernández in Pesquera de Duero, is a 100% Tempranillo varietal wine. The introduction of Pesquera's 100% Tinto Fino wine was, at the time, somewhat controversial, as the considered benchmark Vega Sicilia wines traditionally blended Tinto Fino with such Bordeaux varietals as Merlot, Cabernet Sauvignon and Malbec.
There are other similarities between Rioja and Ribera del Duero. Whereas the wines are quite distinctive as a result of significant differences in terroir, both regions produce wines selected for long aging with highly complex vinification procedures, producing intense, extremely long-lived wines emanating from largely limestone soils. Wines are classified as much for their longevity as their grape quality, and Ribera del Duero produces some extremely well-aging wines. The aging requirements for Ribera del Duero are the same used in Rioja. Wines labelled as "Crianza" must age two years with 12 months in oak. "Reserva" wines must be aged at least three years with at least 12 months in oak. The "Gran Reserva" labelled wines must spend 5 years aging prior to release, two being in oak.
The town of Pesquera is particularly noted for its wines and the area around La Horra (another small town in the region) is respected by locals for its consistent quality. Viña Sastre is one of the region's more respected wine producers and the world-renowned Vega Sicilia easily the most famous. Vega Sicilia's more eminent customers include Prince Charles of the British royal family, while Alex Ferguson's favourite wine is Pesquera. Other notable bodegas include, Dominio de Pingus, Bodegas Alion, and Hacienda Monasterio, all of which lie along The Golden Mile, Spain.
