The vine is the cornerstone for Vega Sicilia of its winemaking. Everything begins with the vine and that is what
establishes the qualities and specific features of the wines that will be,
subsequently, ratified here in the winery.
The 210 hectares used for the vines are divided into
three varieties: Tempranillo, Cabernet Sauvigon and Merlot. Out of these 210 hectares, 140 are used to prepare
Valbuena and Único, and the rest for Alión.
The whole vineyard is structured into 52 different
winemaking plots depending on the grape variety, on the age of the plant and of
the 19 soil taxonomic classifications to be found on the estate.
The minimum age of the plants whose grapes are used
for winemaking is 10 years old and the average age in production is 35. In the
case of the old vineyards such as Ontañón, planted in 1910 after the phylloxera
outbreak, the plots have been studied and analysed to select the clones that
will be used for the parent plants, the plant heritage of the winery.
The vineyard in Vega Sicilia has a 3 x 1.5 m planting
pattern, which means a total of 2,222 plants per hectares with an average yield
of 1 to 1.5 kg of grapes per plant.
The preparation of the land is another of the factors
that is specific to Vega Sicilia. Replanting in the estate is a longer process than normal, as the soil is
disinfected naturally. A selective and biological method is used in our
winery and it dries the artificial products in order to eliminate the nematodes
in the soil that may damage the stocks. Nematicide plants that take five years to clear the land are therefore
used . It should be noted that soil planted with old vines
have high nematode populations and that means that after the old plants have
been removed, a deep cleaning process has to be applied prior to planting the
