Chile's Valle Central, a verdant valley tucked between the Andes and the coastal mountain ranges, has a mild climate and moist soil perfect for grape growing. Made up of four distinct wine regions, Maipo, Rapel, Curico and Maule, the area is criss-crossed by well-traveled wine roads. At the northern end of the valley is Maipo, the oldest of Chile's wine regions, famous for its Cabernet Sauvignon. At the opposite end is Maule, which still grows Pais, the first grape brought to South America.
