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. When it comes to New World wines, and especially wines from the United States of America, Napa Valley is something of a standard bearer. Over its relatively short history, it has managed to transform itself from being a fairly insignificant region, to becoming one of the most important and highly regarding wine locations on earth. With an ideal climate for viticulture, blazing sunshine and a low level of rainfall, this valley is shielded on many sides by mountain ranges which help it maintain a consistent level of heat, light and moisture throughout the year. Today, Napa Valley is a home of innovation and quality, with dozens of grape varietals thriving in the fertile soils. However, the main varietals grown there have always been Cabernet Sauvignon, Chardonnay, Pinot Noir, Merlot and Zinfandel, and the wines they produce are constantly lauded by critics and competitions across the globe.
