Geography of Clare Valley

Situated approximately 130 kilometers north of Adelaide, Clare Valley lies within the picturesque Mount Lofty Ranges. Its Mediterranean climate, characterized by warm days and cool evenings, contributes to the ideal growing conditions for high-quality grapes.
While there are no official subregions, five notable wine-growing areas exist: Auburn, Watervale, Sevenhill, Polish Hill River, and Clare itself. Each boasts a unique soil composition and microclimate, enhancing the diversity of wines produced.
Soil Diversity

The unique soils of Clare Valley are a product of millions of years of geological evolution, hosting eleven distinct soil types. The famed terra rossa, a red earth over limestone, found particularly in Watervale, contrasts with the grey loam over blue slate of Polish Hill River.
