The Mount Edelstone vineyard, situated in the Eden Valley, was planted in 1912 by Ronald Angas, a descendant of George Fife Angas, who founded South Australia. Unusual for its time, it was planted solely to shiraz. The ancient 500-million-year-old soils on the vineyard are deep red-brown clay-loam to clay, resulting in low yields from over 100 year-old drygrown ungrafted centenarian vines. First bottled as a single-vineyard wine in 1952, it became recognised as one of Australia’s greatest shiraz wines.
