Castilla y León, a vast region in north-central Spain, is defined by a high-altitude plateau and a continental climate shaped by the Duero River. The region is known primarily for its red wines, with Ribera del Duero leading the charge with powerful Tempranillo-based wines, though Toro and Bierzo also contribute, alongside emerging white wines. On the southern border is the Sierra de Gredos, a separate region within the same broader area, known for its high-altitude vineyards and elegant Grenache (Garnacha) wines. The diverse soils, ranging from alluvial to sandy, clay, and gravel, combined with significant temperature swings between day and night, allow for the slow ripening of grapes, resulting in concentrated flavors and good acidity.
