Spread across the high plateau of north-central Spain, Castile-León is a land of big skies, cold nights, and ancient vines that have survived where little else thrives. The elevation and dramatic swing between day and night temperatures give the wines real freshness and structure despite the heat of the growing season. Tempranillo dominates the reds, while the Verdejo of Rueda has become one of Spain’s most reliable crisp whites. This is a region where old-vine fruit and serious bones come at prices that still feel fair.
