Undoubtedly the most important viticultural region of the country of Argentina is Cuyo, the arid and red-soiled area within central-west Argentina which produces over eighty percent of the nation's wine each year. Cuyo represents the finest aspects of Argentinian wine making, with wineries in the region celebrating their traditions which stretch back to the sacramental wines first introduced to the country by Spanish settlers hundreds of years ago. As with much of Argentina, Cuyo is most famous for the production of Malbec wines, with Malbec grapes thriving prodigiously in the hot climate of the region, reaching full ripeness in ways they rarely could in their native France, and producing wines of exceptional flavor and quality. The Desaguadero River is the key water source in this otherwise dry and dusty region, and successful irrigation projects have helped bring water to even the driest vineyards within Cuyo. Known as Syrah in most countries around the world, and Shiraz in Australia and certain other regions of the New World, this grape varietal has proven over the centuries to be one of the most powerful and flavorful red wine grapes there is. It is now one of the planet's most widely grown grapes, and is a favorite with wineries as a result of its robustness and versatility. It isn't easy to identify many characteristics of this particular varietal, due to the fact that it is highly versatile and shows significant differences in flavor and character depending on the terroir it is grown in, and the climatic conditions of the region. However, Syrah is most widely associated with full bodied, strong and loud red wines, packed full of fruity and spicy flavors, held in a beautifully deep red liquid.
