The Clare Valley is something of a contradiction: cool enough to produce pristine Riesling, but warm enough to fully ripen Shiraz and Cabernet. This is due to the region’s variable topography, from the higher altitudes of Polish Hill River at 500m (1,640 feet) in the north, down to the warmer, earlier-ripening soldier’s blocks at Leasingham.
Summers are marked by clear, warm to hot days, low humidity and notable drops in nighttime temperatures in March as picking begins, allowing for good acid retention. Annual rainfall is approximately 630mm (25 inches) and due to lack of water, the majority of vineyards are dry-farmed.
Soil types are variable, but are mostly red loam over limestone around Watervale, while farther north in the Polish Hill River region red-brown clay loam over slate sub-soil predominates.
