A grape varietal which certainly requires no introduction, Cabernet Sauvignon is not only the principal component of the great Bordeaux wines, but also reigns as the grape varietal most widely known for putting the U.S. on the wine making map. It is grown prolifically throughout America, perhaps at its best in Napa, Sonoma and Washington. Even though in this country we see many 100% varietally based wines, Cabernet Sauvignon is usually blended to add complexity and to round out the often tough-to-handle tannins which are characteristic of this wine. It should be full-bodied, rich, firmly structures and powerful. It is reserved in the bouquet, yet the tell-tale black currant, dark berry, cedar and vanilla (from oak barrels) often show themselves. When grown in a cool climate, it can smell of green pepper or olives, but beware of unripe fruit that can be weedy or even vegetal. Some of its popular grape blending companions include Merlot, Cabernet Franc, Malbec and Petit Verdot.
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.
