Maule Valley?is the largest wine-producing region in Chile other than the?Central Valley, of which it is a part. It has 75,000 acres (30,000ha) under vine, and has traditionally been associated with quantity rather than quality. But this is rapidly changing ? the bulk-producing?Pais?vine is gradually being replaced with more international varieties such as?Cabernet Sauvignon?and?Carmen?re, and careful winemaking practices are being employed to make some world-class red wines from?old-vine?Carignan.
