Max Schubert's experimental work in the 1950s confirmed that South Australian Cabernet of the period was unreliable, he recognised that Grange should be based on a spectrum of fruit. One of the great strengths of Grange is that it does not rely on the performance of a single vineyard. The 1984 Grange is predominantly Shiraz with a small amount (5%) of Cabernet Sauvignon from the Kalimna and other Barossa Valley vineyards, Magill Estate, Coonawarra, McLaren Vale and Clare Valley. Generally good weather for the vintage, a cool summer followed by dry conditions towards the harvest season. Maturation in new American oak hogsheads for twenty months. Alcohol 14.2%
