Chile offers wines such as fruity, oaky Chardonnays, delicious Cabernet Sauvignons and tempting Merlots. Chile is most famous for ungrafted vinestock. Through some remarkable fate, the plague of phyllorexia has never embarked upon the region and hence grafted vinestock is not needed. Interesting Chilean grape varieties include the Pais and the and the Carmenere. A recent influx of modern techniques and technology has given the region new fervor for the industry. Chilean winemaking regions include Aconcagua, Casablanca, Maipo, Rapel, Curico and Maule, and Bio Bio. Superstar Chile wines include the Caballo Loco, Cousino Macul's Finis Terrae, Montes "M", Erazuriz's Sena and Almaviva. Chile's dry climate depends on the Pacific ocean and Andes mountain range for the ability to produce grapes. Most of the wine growing regions are at the south end of Santiago. Chile has grown into the fourth largest exporter of wines to the United States.
