their barb-wire fence one night and pruning their vines. The export driven Australian wine industry was well situated for the Chardonnay boom of the 1980s and 1990s and Australia responded with a unique style of wine that was characterized by big fruit flavors and easy approachability. To compensate for the very warm climate, richness was enhanced by the use of oak chips and acid was added during fermentation. During this period the number of Chardonnay plants increased fivefold and by 1990 it was the most widely planted white wine grape in Australia and third most planted overall behind Shiraz and Cabernet Sauvignon. Early in the 21st century, demand outpaced supply and there was a shortage of Chardonnay grapes which prompted Australian winemakers to introduce new blending partners like Sémillon (known as "SemChard") and Colombard. Being a rather neutral grape, Australian winemakers first approached Chardonnay in the same manner they were making wine from the similarly neutral Sultana grape. Aromatic yeast were added and maceration was extended to get more flavors from skin contact. While the style of Australian Chardonnay is mostly characterized by the mass-produced products of the hot Riverland region, the cooler climates of the Southern Highlands in New South Wales, Victoria and Tasmania have been creating more crisp, less oaked wines with lime notes. In the Cowra region, Chardonnay's citrus notes are emphasized while Hunter Valley examples have more richness and smoky notes. The Adelaide Hills and Yarra Valley produce a more Burgundian style while Mount Barker in the Great Southern wine region of Western Australia produces Chardonnay that more closely resembles those of Chablis. A rare, isolated clone exists in the Mudgee region that locals believe traces its ancestry back to some of the first vines brought to Australia in the 19th century. While the wine made from this clone is not particularly distinguished, it can still be of very good quality. Overall, there has been a shift in style since the 1980s from deep golden, oily wines with melon and butterscotch flavors to lighter, paler Chardonnays with more structure and notes of white peaches and nectarines. Sparkling wines from Chardonnay are produced in the cool regions of Geelong, Adelaide Hills, Macedon Ranges and Tasmania. Despite being more famous for its Sauvignon blanc production, Chardonnay was New Zealand's most widely planted grape variety from 1990 till 2002 when Sauvignon blanc finally surpassed it.
