Ribera del Duero
Ribera del Duero is located in the central, northern part of Spain, on the Duero river. It is home to many icons of Spanish winemaking; estates which produce red wine using the Tempranillo grape (locally known as Fino Tinto) often blended with Bordeaux varieties Merlot, Cabernet Sauvignon and Malbec. The grapes, grown on limestone soils, produce intense, long-lived and highly complex wines, usually through extended vinification processes. 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.
