This bulletin details what is special and unique about the geology, soil and climate of the south-west of Western Australia (WA), an area that encompasses the state’s 9 wine regions.
We have arranged the information into 2 parts:
- In Part 1, we broadly describe the special geological, soil and climate features of the south-west of WA to provide context for the wine regions.
- In Part 2, we describe the geology, soil and climate of the regions and subregions of the Geographical Indications (GI) scheme (administered by Wine Australia) for WA.
Through this work we have found that the wine regions of south-west WA are unique and special in many ways and believe that the combination of characteristics contribute to the south-west’s reputation for producing the grapes that make fine wines. Although we are still a long way from fully understanding the interactions between environmental conditions and wine production in WA, 3 features of the south-west stand out:
- the ubiquitous ironstone gravelly soils
- the ancient granitic geology
- the influences of afternoon sea breezes, such as the Fremantle and Albany doctors.
This study only describes the regions contained within the GI scheme’s South-west Australia Zone and the Greater Perth Zone. The other GI zones in WA have no regions allocated to them, despite the presence of a few isolated vineyards. Viticulture in these other zones is mainly limited by climatic conditions, water availability and isolation.
