It is the Vega Sicilia flagship. The qualities of the Tempranillo and cabernet sauvignon in different proportions are assembled to perfection in this wine. Each provides a differentiating factor that makes the wine great in every vintage. The vines are grown on plots where the land is located at the point between the slopes down from the wasteland and the alluvial plain. The soil nearest the surface is made out of fine colluvial deposits from the hillside with small fragment of limestone. There is abundant quartz gravel deeper down in a sandy main soil. There are many angular limestone boulders on the surface. Red wine made in controlled fermentation using native yeast in wooden tanks. Malolactic fermentation also takes place in wood. After its fermentation, its goes through what is probably the world's longest ageing of a red wine, almost 10 years between wood and bottle. The different stages take place in different types of barrel: American and French wood, new and used 225-litre barrels, 20,000-litre vats, each batch is what determines the type of wood and the time spent in each container.
