Clare Valley
South Australia’s other great Riesling region, producing bone-dry, lime-driven wines.
Dry Riesling with intense lime and lemon, bone-dry, very high in acidity, and famously long-lived — it develops a toasty, honeyed character over a decade. Also firm, structured Cabernet and Shiraz.
About Clare Valley
Clare Valley Riesling is the archetype of the Australian dry style: intense lime and grapefruit, searing acidity, no residual sugar and a long life ahead of it.
Clare producers were early and near-universal adopters of screwcap, specifically to protect these wines from cork taint and premature oxidation.
A set of narrow valleys at 300 to 500 metres, hot by day and sharply cold at night, which is an unusual combination for a region this far inland. Watervale and Polish Hill are the two names that appear on labels, and they differ: Watervale is on limestone and gives softer, lime-scented Riesling, while Polish Hill is on slate and shale and gives a harder, slower-developing wine.
It was the region that led the Australian move to screwcap: a group of Clare producers switched together for the 2000 vintage, specifically to protect Riesling’s aromatics from cork variation. The industry followed, and it is the clearest example of a closure decision made on evidence rather than tradition.

Clare Valley has a warm climate with continental and altitude influences, at roughly 33.8° of latitude. The gap between day and night temperatures is very large. Rainfall falls mostly in winter, leaving a dry growing season. Drought is a serious constraint. Hot days and cold nights at 300–500 metres. The swing is what preserves the acidity that defines Clare Riesling.
Vintage variation
Vintage matters little
Reliable sunshine, low disease pressure and — often — irrigation to smooth out what rainfall does not deliver. The grapes ripen every year.
- Latitude. At around 34°, there is more heat available than the vine needs in most years.
- Rainfall timing. The rain arrives outside the growing season, so harvest is usually dry. This removes the largest single source of vintage variation.
- Continental influence. No large body of water to buffer the extremes. Continental places have hotter summers, colder winters and sharper frost risk, all of which widen the gap between years.
Derived from the climate above, not from anyone’s view of particular years. Why there are no vintage scores here.
These are influences on how a wine turns out, not determinants of it. Picking date, yield, vine age and every winemaking decision sit between the climate and the glass.
