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. Despite being one of Italy's smallest wine regions, the central Italian region of Umbria is a vitally important one, and home to many of the country's finest and most historic wines and wineries. The reputation of Umbrian wines may have suffered in the 1970s, along with the produce of much of the rest of the country, but the 1980s and 1990s saw significant efforts made by vintners when it came to improving their produce and overall image. By consulting international oenologists, the wineries of Umbria were able to update their traditional techniques, and produce considerably finer wines from their Sangiovese grapes, as well as from imported varietals such as Cabernet Sauvignon, Merlot and Chardonnay. Indeed, the barrel fermented white wines of Umbria, now made with a blend of Chardonnay and Grechetto varietal grapes, has gone on to be something of a flagship product for the region, and is regarded as one of the best and most characterful white wines in Italy.
