Of all the white wine grape varietals, surely the one which has spread the furthest and is most widely appreciated is the Chardonnay. This green skinned grape is now grown all over the Old and New Worlds, from New Zealand to the Americas, from England to Chile, and is one of the first varietals people think of when considering white wine grapes. Perhaps this is because of its huge popularity which reached a peak in the 1990s, thanks to new technologies combining with traditional methods to bring the very best features out of the Chardonnay grape, and allow its unique qualities to shine through. Most fine Chardonnay wines use a process known as malolactic fermentation, wherein the malic acids in the grape juice are converted to lactic acids, allowing a creamier, buttery nature to come forward in the wine. No grape varietal is better suited to this process than Chardonnay, which manages to balance these silky, creamy notes with fresh white fruit flavors beautifully. 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.
