Vega Sicilia own and operate 250 hectares of the most splendid winegrowing terroir on the Ribero Del Duero. The exacting standards involved in making Valbuena begins with the husbanding of vines, which are controlled down to each detail. Vega Sicilia have established limits to the production of the estate's vines, all are dry grown and hand pruned, yielding less than two kilos each. A cepage of varying proportions, Tempranillo and Merlot, Malbec and Cabernet Sauvignon, the separate vintages of Vega Sicilia are treated to an extended maturation in a selection of new and seasoned, French and American oak casks and larger format vats for many years, followed by assemblage and bottle ageing before release.
