Valbuena, is the purest expression of the Tinto Fino (Tempranillo) in Vega Sicilia. Tinto Fino is clearly the predominant wine in the assemblage of the varieties that make up this magnificent wine. The other variety used is Merlot, which is added to a greater or lesser extent depending on the vintage.

The Valbuena Tempranillo is obtained from plots located on gentle concave slopes that descend from the wasteland. Those soils are made up of material that was eroded and accumulated as colluvial on the lower slopes, developing a high profile soil, with a specific important evolution with the formation of a deep calcic horizon.
