The varietal that represents a significant percentage of white wines from Castilla-La Mancha is Airen. This grape is the most widely planted white grape variety in Spain and is particularly known for thriving in the hot, dry conditions typical of the Castilla-La Mancha region. Airen produces wines that are often characterized by a light body and fresh, fruity flavors, making it a popular choice for both bulk wine production and quality wines that reflect the local terroir.

In contrast, while Palomino is primarily associated with sherry production in the Jerez region, and varietals like Chardonnay and Sauvignon Blanc are more commonly associated with cooler wine regions, Airen is deeply intertwined with the identity of Castilla-La Mancha. Its adaptability to the region's climate contributes significantly to local wine production, which is why it stands out as the dominant white varietal in that area.
