The beautiful and historic name Mount Edelstone is a translation from the German Edelstein meaning ‘gemstone’, a reference to the small yellow opals once found in the area. The Mount Edelstone Vineyard was planted in 1912 by Ronald Angas, a descendant of George Fife Angas who founded The South Australian Company and played a significant role in the formation and establishment of South Australia. Unusual for its time, the vineyard was planted solely to shiraz. The ancient 500-million-year-old geology in the vineyard has given rise to soils that are deep red-brown clay-loam to clay, resulting in low yields from the dry-grown, un-grafted centenarian vines. The wine was first bottled as a single-vineyard shiraz in 1952 by fourth-generation Cyril Henschke.
