The wine region of Toro is a predominantly red-wine appellation in Castilla y León in north-western Spain. Toro is situated in the province of Zamora, west of the Rueda and Ribera del Duero wine appellations, and in the Spanish Duero river valley near the Portuguese border. The Spanish word toro means 'bull'. While it is unclear precisely how the town's name came about, the bull is nonetheless a fitting symbol for these robust wines.
