Tempranillo is a variety of vitis vinifera, the red grape used commonly in winemaking. It is native to northern Spain, and widely cultivated in both northern and central Spain. It is also fairly common in Argentina, and plays a minor role in the wines of two regions of Portugal, the central Alentejo, where it is known as Aragonez and used in red table wine blends of variable quality, and Douro, where it is known as Tinta Roriz and mainly used in blends to make port wine.
