La Mancha is the largest delimited wine region not only in Spain, but in the whole of Europe. Occupying almost one half of the large Castilla-La Mancha region, the La Mancha viticultural area covers a vast expanse of the central Iberian plateau, and is bordered by Valencia and Murcia to the east, Extremadura to the west, Andalucia to the south and Madrid to the north-west. There are more than 500,000 acres (202,350ha) of vineyard here, spread over 182 municipalities and four provinces (Albacete, Cuenca, Ciudad Real and Toledo).
