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. The vast region of South Australia is home to a wide variety of vineyards, growing a large range of different grape varietals. Because the South Australian wine region is so large, it benefits from a great array of climatic conditions – from dry and hot, to cool and windy – which wineries can use to their advantage when it comes to selecting the grape varietal they wish to thrive in a particular sub-region. South Australia is most commonly associated with the big, powerful and fruit-forward Shiraz wines which are produced in the cooler valley areas of the region, but recent decades have seen something of an explosion in the South Australian wine industry, leading to wineries expanding their repertoire enormously and experimenting with other fine grape varietals and making the most of their unique terroir.
