Airén is a white wine grape. It is native to Spain where it represents about 30% of the total wine production.
In 2017, Airén was estimated to be the 4th most grown grape variety in the world.
But, Airén plantations are declining and being replaced in Spanish vineyards with more popular red varieties like Tempranillo.
Because of a too bold style, high sugar level and low acidity, Airén is most often blended with other grapes to make a more balanced wine, or fermented and distilled for Brandy or fortifying wines such as Sherry.
In the Canary Islands, Airén is called Burra Blanca ("White Donkey").
