Region
The Valley runs from Stirling in the South to Ashton in the North. The Valley bed sits at just over 400m altitude and the highest hill is Mount Lofty at 727m. The vineyards are situated at altitudes of 450m – 600m, and are on small internal undulations, with slopes from 10°C to 20°C that give aspects to many points of the compass. The amount of heat received by a site is very orientation dependent. The geology of the Piccadilly Valley consists of pre-cambrian sediments ranging from 1,600 million years-old calcsilicates to 700 million years-old phyllites, shales, sandstones and quartz-rich strata. The soils are podsolised duplex, sandy to clay loams and the geology is from either Woolshed Flat Shale, Basket Range Sandstone or Barossa Complex. It is interesting to note that the development of Australian sparkling wine production following the Traditional method used in Champagne started simultaneously in the Piccadilly Valley and in Tasmania.
