Clare Valley wine region

The Clare Valley wine region is one of Australia's oldest wine regions, best known for Riesling wines. It lies in the Mid North of South Australia, approximately 120 km north of Adelaide. The valley runs north-south, with Horrocks Highway as the main thoroughfare.Extent and appellationClare Valley wine region covers an area adjoining the both sides of the Horrocks Highway as it passes through the town of Clare near its northern extent and the town of Auburn near its southern extent. The region is located at the northern end of the Mount Lofty Ranges zone with its southern extent being about 100km north of the Adelaide city centre. The Clare Valley wine region was registered as an Australian Geographical Indication on 25 March 1997.Soil and climateThe wines are planted from 400to. The climate is moderately continental, with cool to cold nights and warm to hot summer days. The higher altitude, compared to other wine regions in South Australia, ensures cool nights even during the heat of summer allowing the fruit to ripen more evenly and slowly. Rainfall is predominantly in winter - spring (June - September) with an annual average of around 630 mm. Summers are dry and make irrigation desirable but also ensure a minimum of fungal diseases. Varied soil types throughout the valleys are another feature, ranging from red to brown grey over basement rock.
