If ever there was a list of Australian terroirs, Clare Valley would be near the top. Its location an hour north of Adelaide, its latitude and heat degree days (over the growing season) suggest a very hot clime suited to reds, yet white wines prevail. Taut, lime-sherbet Rieslings with fine minerality and ageing capacity are the region's most famous product, followed by Shiraz and Cabernet Sauvignon.

If ever there was a list of Australianterroirs, Clare Valley would be near the top. Its geographical position an hour north of Adelaide, its latitude and heat degree days (over the growing season) suggest a very hot clime suited to reds. Yet white wines prevail as these factors are offset by an average altitude of 398m (versus Geisenheim at 100m), low relative humidity (37 percent versus 56 percent), high sunshine hours, significant continentality levels (albeit less Geisenheim), cooling south-westerly sea breezes and prime, low, fertile red loam over marly limestone and shale soils set in cooling hill pockets. Irrigation is strictly controlled and less called for in the dry climate.
The town of Clare, founded by Irishman Edward Gleeson in 1840, first prospered on the back of copper mining, then a wheat and wine boom during the late 1800s. Vines were first planted in 1853 by an itinerant Cornishman at a site near present-day Watervale, and Birks Wendouree was founded before the century was over. The corporates moved in during the 1960s dry-wine boom, although there remains a core group of small, family-owned estates.
