Species: Vitis vinifera
The variety is most likely a selection from northern Spain, but some believe that Tempranillo originated in southern France as a natural hybrid of Cabernet franc and Pinot noir.
Tempranillo vines are productive to very productive, capable of bearing medium to large crops of 8 to 12 tons per acre. High yields may sacrifice color intensity and fruit flavors, significantly reduce acid level, and increase pH while delaying harvest.
Tempranillo produces good- to excellent-quality wines with good color under optimum conditions, especially at lower crop levels. The wine can have distinctive varietal character. Its uses range from good blending varietal to high-quality varietal table- or port-wine blends. Future interest in Tempranillo as a premium wine should increase for all areas, although lack of marketing and consumer awareness may limit its overall importance.
