About the Vineyard

Pioneer Charles Crane, after whom the village of Craneford is named, established the region in 1866, on a tributary at the source of the North Para River near Eden Valley. In 1877 George Crossman Thyer purchased a nearby property at the top of the range overlooking the valley, from a tract of land granted to George Fife Angas in 1856. This land was in the fertile area called Flaxmans Valley, named by German geologist Johann Menge in 1839. After Thyer’s death it was transferred in 1912 to Joseph Hill Thyer, who pioneered the first vines on this property.

Cyril Henschke purchased the property from his son Kenneth Crossman Thyer in 1966, and established a large planting of predominantly riesling and shiraz at a time when riesling was scarce and bonuses were being paid by the large wineries. Today the riesling is the source of the Julius Eden Valley Riesling, named in honour of Stephen's great-uncle Julius Henschke, a highly acclaimed artist and sculptor, while the shiraz is used in the Keyneton Estate Euphonium blend. This wine is named after the early English pioneer Joseph Keynes who settled at Keyneton in 1842 and after whom the village was named.

Other plantings subsequently took place. The cabernet sauvignon is the source of the Cyril Henschke, the wine made to honour the fourth generation of the Henschke family and one of Australia’s outstanding winemakers and pioneers in the production of varietal table wines. In addition, it was Cyril who in 1958 created the wine that has so captured the heart of red wine drinkers around the world, the Hill of Grace. The cabernet franc and merlot are used as blending components of the Cyril Henschke Cabernet Sauvignon. The 1983 Cyril Henschke Cabernet Sauvignon won the Tucker Seabrook Trophy judged as the best Cabernet in all national wine shows. The semillon provides fruit for the Louis Eden Valley Semillon, named in tribute to vigneron Louis Henschke who tended the Hill of Grace vineyard for 40 years. The Cranes Chardonnay is named after Charles Crane and the Joseph Hill Gewürztraminer is named after Joseph Hill Thyer. The Eleanor’s Cottage Sauvignon Blanc is blended with Semillon and is named after Eleanor, the wife of George Crossman Thyer, who built their settlers cottage on the tributary of the North Para River, adjacent the sauvignon blanc vineyard.

The Henschke Eden Valley vineyard is located in the cooler part of the Mount Lofty Ranges, in the Barossa Range just east of the Barossa Valley, at an altitude of 500m and a rainfall of 700mm. The vines are planted on their own roots on a contour planting to conserve soil moisture and reduce erosion. They are effectively dry grown, although the soil moisture is monitored and in drier years drip irrigation is used to keep the vines physiologically active. Vines are planted on a spacing of 3.4m between rows and 2m between vines, and yield an average of 5 t/ha. There are a number of trellis types ranging from single wire to VSP (Vertical Shoot Positioned) and Scott Henry. There is ongoing research on canopy management and trellis style. A clonal research trial for semillon, including old and new clones, is being run and eutypa control trials on shiraz will help discover ways of improving the longevity of old vines.

The Eden Valley vineyard is on a range of well-drained duplex soils from sandy loam over gravel and bedrock with patches of clay to sandy loam over clay. Originally the ground was cultivated for weed control. Nowadays the vineyard has a permanent sod culture of early-maturing perennial rye and cocksfoot grasses in the row. A wheat straw mulch is used under the vines to retain soil moisture, build up organic matter, and inhibit weed growth. Prediction of disease pressure through an integrated pest management program results in minimal chemical input in the vineyard. Organic and biodynamic practices are being introduced.
