Ossian produces Verdejo wines from Castilla y León, Spain's largest wine region. The winery focuses on this native white variety, which thrives in the region's continental climate and limestone soils. Viñas Viejas Verdejo, the flagship expression, has earned recognition from Wine Advocate, Falstaff, Decanter, and Wine Enthusiast. The portfolio includes Verdling Trocken and Quintaluna, each showcasing different facets of Verdejo's mineral character and textural range. Verdejo itself is a high-acid, aromatic white with stone fruit and herbaceous notes—a variety increasingly central to Spain's reputation for distinctive, food-friendly whites. Ossian's commitment to the grape reflects Castilla y León's emergence as a serious source for quality white wine.
