Carneros is one of California's key wine producing regions, situated close to the Pacific coast. Although Carneros is relatively young, having been first used for viticulture in the 1940's, it has proven to be a highly successful region, capable of growing high quality grapes and producing wines of real character and distinction. Unlike many other regions of California, Carneros is considerably cooler, and benefits from the tempering effect of Pacific fog on the vineyards. As a direct result of this, Carneros wineries are able to produce fine grape varietals which require cooler temperatures, such as Chardonnay and Pinot Noir – grapes perfect for the sparkling wines the region has become famous for. However, plenty of still red and white wines are made in the region, from a wide array of grape varietals. 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.
