The Riverina wine region, located in south-central New South Wales, is one of Australia's largest and most productive wine regions, accounting for a significant portion of the country’s wine output. Centred around the city of Griffith, Riverina has a warm, dry climate supported by extensive irrigation from the Murrumbidgee River, enabling consistent, large-scale viticulture. While the region is best known for its high-volume production of popular varietals such as Shiraz, Chardonnay, and Merlot, it also has a reputation for producing premium-quality botrytis-affected Semillon, often referred to as Australia's answer to Sauternes.

The combination of fertile soils, reliable sunshine, and water access has made Riverina a powerhouse for both domestic consumption and export markets. Despite its industrial scale, the region is home to a growing number of family-run wineries focused on quality and innovation, adding diversity to its wine offerings.
