Excellent Langtons Classification. The Dalwhinnie vineyard is situated on the 37th parallel, within a unique amphitheatre which has its own unique mesoclime. The poor fragile soils left over from alluvial mining projects in the early 1800s are some of the hardest and hungriest anywhere. The first Shiraz vines, planted to the Grand Piano Block, were rootlings from the eminent Sunraysia Nurseries at Mildura. The site is totally frost free and harvests achieve complete physiological ripeness nine out of ten years, all vintage releases must surpass expectations.
