Changing Tastes and Climate Push Australian Winemakers Toward Volcanic Slopes

Climate Pressures and Shifting Palates

Australian winemakers are increasingly sourcing grapes from cooler, high-altitude regions as a changing climate and shifting consumer preferences challenge traditional production areas. Industry participants and regional associations report that a decade-long trend toward lighter-style wines has accelerated the movement of fruit across regions.

Traditionally warmer areas, such as the Hunter Valley in New South Wales, face growing difficulties in cultivating lighter styles. Consequently, some Hunter Valley wineries supplement their production by purchasing grapes from cooler regions like Orange in the Central West.

The Appeal of the Orange Region

Located around the slopes of the ancient extinct volcano Gaanha Bula-Mount Canobolas, the Orange wine region benefits from high altitudes ranging between 600 and 1,390 metres above sea level. This geography provides:

• Nutrient-rich volcanic soils suited for agriculture
• Cooler ambient temperatures that support lighter wine styles
• Favourable conditions for growing varieties like pinot noir

According to Wine Australia's National Vintage Report, Orange produced nearly five times the quantity of pinot noir compared to the Hunter Valley, highlighting the regional divergence in grape output.

Industry Adaptation and Regulations

While exact figures on outsourced grapes remain difficult to quantify, local growers and industry figures suggest that a significant portion of fruit processed in the Hunter Valley originates elsewhere. Industry representatives note that sourcing fruit from external regions helps maintain supply consistency during periods of variable weather, including extended heat periods and intense rainfall.

Under Wine Australia guidelines, regional labelling requires at least 85 percent of the grapes in a bottle to originate from the stated region, though wines can be sold anywhere provided labels accurately reflect their composition.
