Indeed, fifty years young. As Wine Australia put it in the intro to a recent celebratory tasting: "With the first varietally-labelled Chardonnay produced in Australia in 1972, now is the perfect time to revisit the story of Australia’s most iconic white wine. From the first vine cuttings in the 1830s to the big buttery wines of the 1990s, to today’s regionally distinct refined styles, Australian Chardonnay has come a long way."
