What is the most widely planted grape variety in Spain?

The most widely planted grape variety in Spain is Airen. This white grape, primarily grown in the central regions of the country, is known for its resilience and ability to thrive in hot, dry climates. Airen is often utilized for producing a range of wines, from fresh, dry whites to those suitable for blending. Its popularity stems from its adaptability and the fact that it produces large yields, making it preferable for many growers.

While Tempranillo, Macabeo, and Garnacha are also important and widely recognized grape varieties in Spain, they do not match the planting extent of Airen. Tempranillo is highly prized for red wines and has gained international acclaim, while Macabeo is known for quality white wines, particularly in regions like Rioja and Cava. Garnacha, another prominent red variety, contributes to some of Spain's most famous wines but still does not compare to the large vineyard areas planted with Airen.
