Airén

Airén is a variety of Vitis vinifera, a white grape commonly used in winemaking. This grape is native to Spain where it represents almost a quarter of all grapes grown. As of 2017, Airén was estimated to be the world's fourth most grown wine grape variety in terms of planted surface, at 252,000 hectares (620,000 acres), an increase from 218,000 hectares (540,000 acres) in 2004, where it held 1st place, although it is almost exclusively found in Spain.

Since Airén tends to be planted at a low density, several other varieties (including Cabernet Sauvignon and Merlot) are more planted in terms of number of vines.
