Merayo produces wines from Bierzo, the acclaimed red wine region of Castilla y León in northwestern Spain. The winery focuses on Mencía, the indigenous dark-skinned grape that defines the area's character—a variety known for its mineral precision, moderate tannins, and ability to express the region's slate-rich terroir. El llano, the winery's flagship, has earned recognition from Wine Enthusiast, Wine Advocate, and Decanter. Aquiana Bierzo and Las Tres Filas Mencia Bierzo round out the portfolio, each showcasing the depth and structure that Bierzo's cooler climate and elevation impart to Mencía. The wines reflect the region's reputation for producing elegant, food-friendly reds with distinctive character.
