Vega Sicilia is unquestionably a unique wine, one of the great Spanish classics. It's personality is derived from the quality of fruit and uncompromising attention to detail. At Vega Sicilia, the oak cask is an essential part of the vinification, forging a true consortium with the wine. In the same way that the grape is an achievement of the vineyard itself, it is essential for Vega Sicilia that most of the casks are coopered at the winery. A cepage of varying proportions, according to vintage, Tempranillo and Malbec, Merlot and Cabernet Sauvignon, Vega Sicilia Valbuena is treated to maturation in a selection of new and seasoned, French and American oak casks and larger format oak vats for up to three years.
