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. Situated in the north-western part of Italy, the region of Piedmont is known worldwide and is highly respected for the quality of the wines produced there. Many of the most successful sub-regions in Piedmont produce many of the world's finest red wines, such as those made from the excellent Nebbiolo grape varietal in areas such as Barolo and Barbaresco. However, the historic wineries which typify this region use a relatively wide variety of grapes, including Dolcetto and Barbera for their red wines, which are typically aged and have a delightful velvety character. Piedmont isn't all about beautifully complex red wines, though, as it is also famed for high quality, elegant sparkling wines, notably the Asti wines made with the white Moscato grape. The region benefits from a range of terroirs which are often well expressed in the sparkling wines, and a wonderfully consistent climate ideal for vineyard cultivation.
