The Clare Valley is actually a series of narrow north to south valleys, each with a different soil type and slightly different weather patterns along their stretch. In the southern heartland between Watervale and Auburn, there is mainly a crumbled, red clay loam soil called terra-rossa and cool breezes come in from Gulf St. Vincent. A few miles north, in Polish Hill, is soft, red loam over clay; westerlies blowing in from the Spencer Gulf influece this area's climate.
The differences in soil, elevation, degree of slope and weather enable the region to produce some of Australia’s finest, aromatic, spicy and lime-pithy Rieslings, as well as excellent Shiraz, Cabernet Sauvignon and Malbec with ripe plummy fruit, good acid and big structure.
Clare Valley is an isolated farming country with a continental climate known for its warm and sunny days, followed by cool nights—perfect for wine grapes’ development of sugar and phenolic ripeness in conjunction with notable acidity levels.
