Maule is one of Chile's oldest wine regions as well as currently being it's largest production area. New projects push its borders toward the sea but the real attraction here is its ancient head-trained, dry-farmed Pais and Carignan. Some of the valley's vineyards are more than 100 years old and many have been organically managed since their inception. Grapes were originally solely used for simple wines for local consumption but winemakers now use modern vinification techniques to produce fine quality fresh and fruity wines that are gaining attention in Chile and abroad. Placing renewed value on old vines has given rise to innovative projects such as VIGNO in which several wineries, including Undurraga, work together to promote excellent old vine Carignan.
