Which region is recognized as being located on the Mediterranean coast of Spain?

Levante is the correct choice because it refers to a geographical area along the eastern Mediterranean coast of Spain, encompassing regions known for their influence on winemaking due to the warmer, dry climate conducive to grape growing. This area includes provinces like Valencia, Alicante, and Murcia, which are known collectively as the Levante or the East region in Spain.

Rioja is primarily located in northern Spain and is known for its red wines, primarily made from Tempranillo grapes. La Mancha is situated inland, south of Madrid, and is one of Spain's largest wine-producing regions, primarily known for its production of white wine from the Airén grape. Priorat, on the other hand, is located further inland in Catalonia, known for its robust reds and a rugged landscape, not directly on the Mediterranean coast. Therefore, Levante is the region that fits the description of being located on the Mediterranean coast of Spain.
