The fruit is predominantly from the Mount Langi Ghiran vineyards in The Grampians, Victoria, and Shiraz growers from Heathcote, Bendigo, and Swan Hill play a supporting role. The Mount Langi Ghiran vineyard is 350 metres above sea level and set between the namesake Mount Langi Ghiran (922m) and Mount Cole (760m). The mountains create a cooling effect as cold air tumbles down and into the valley. The shadow cast shortens the effective sunshine hours in autumn, extending grape ripening and contributing natural acidity and intense fruit flavours. Mountain erosion over time has created a unique profile of granite sands over sedimentary red clay loam. The texture of this soil profile is ideal for moderating the natural vigour of the Shiraz vine. It contributes to the subtle spicy pepper flavour that has made Mount Langi Ghiran renowned. These raw climate, soil, and vine elements combine to create this unique vineyard, one of Australia's most isolated. The weathered granite cliff face and sedimentary soils, the cold prevailing winds forming off the Southern Ocean, and the historic vine stock all play a critical role in producing the distinctive flavour.
