The Castile and León appellation, located in the north-west of Spain, is a renowned wine region encompassing several sub-regions with distinct wine-producing characteristics. This vast area is known for its production of high-quality wines that blend tradition with innovation. Among the most famous domains is Ribera del Duero, renowned for its powerful reds primarily based on Tempranillo, often compared to the great Bordeaux wines for their complexity and ageing potential. Rueda, another notable sub-region, is recognised for its vibrant and aromatic white wines made from the Verdejo grape, offering tropical fruit aromas and captivating freshness. Toro, with its robust and concentrated reds, also focuses on Tempranillo, locally known as Tinta de Toro. Thanks to a continental climate with hot summers and cold winters, coupled with a variety of soils, the wines of Castile and León benefit from a diverse terroir. This region, rich in wine history and culture, continues to appeal to both enthusiasts and connoisseurs, affirming its crucial role in the Spanish wine landscape.
