A wine region located east of Melbourne, Victoria. It is a cool climate region that is best known for producing Chardonnay, sparkling wine and Pinot Noir. Its proximity to the urban centre and high profile wineries have made it an important destination for ecotourism.

The westernmost point of the Yarra Valley is Whittlesea, north to Kinglake, east to Mount Gregory and south to Gembrook. It is divided into 2 subregions: the Valley Floor and the Upper Yarra, with distinct altitudes, soils, rainfall and climates.

Australian Chardonnay has long been associated with a deep, oily, buttery style that experiences full malolactic fermentation and excessive amounts of oak treatment, that has since gone out of fashion. Australia's cooler wine regions, especially the Yarra Valley, are leading the charge on leaner, acid-driven styles of Chardonnay, more closely aligned with Burgundy, with winemakers reducing or entirely preventing malic acid conversion and reducing both the duration of oak maturation and the percentage of new oak used.
