Chardonnay wine from New South Wales - Australia. From The Hunter Valley. It regional Geographical Indication is officially just 'Hunter', is unquestionably New South Wales' best-known and most-prized wine zone. It was here that the country's first Chardonnay (now its most popular white variety by far) was grown in the early 1970s. The Hunter Valley was also home to James Busby, the 'father' of winemaking in Australia and New Zealand, whose pre-phylloxera European vine cuttings were the ancestors of some of Australia's finest vines.
