The wine co-operative San Pedro Regalado was founded in 1958 by the people of the small village of La Aguilera in the Ribera del Duero wine region. The founding members embraced the spirit of the co-operative movement - that their combined efforts would reap greater rewards than each winemaker working individually. Grapes are all sourced from the small co-operative vineyard sites around La Aguilera, with many of the vines being over 100 years old. The Ribera del Duero is considered one of the most prestigious wine regions in Spain. It concentrates almost entirely on the production of fine red wines using the Tempranillo grape (known locally as Tinto del Pais). In Ribera del Duero Tempranillo yields smaller berries, loose clusters and tougher skin, which encourages more skin-to-juice contact and promotes full-bodied, powerful wines that still retain the grape's renowned elegance. This combination of power and elegance represents Tempranillo's signature in Ribera del Duero, and the region's greatest contribution to winemaking today.
