Vega Sicilia is widely regarded as the greatest wine producer in Spain. The estate in Ribera del Duero is known for its dense, complex red wines made principally from the Tinto Fino (Tempranillo) grape variety. Its top wine, Unico, is one of Spain's most expensive and sought-after wines. Since its founding in 1864, the winery has brought international acclaim to Ribera del Duero, a region in northern Spain formerly overshadowed by the more famous Rioja. Many believe Vega Sicilia’s commitment to quality earned Ribera del Duero its rightful place as one of the world’s highest-quality wine regions.
