Vintage 1977 was finished with a higher proportion of Cabernet Sauvignon, weighing in at a hefty nine percent. A collation of exceptional harvests, the backbone from the spiritual home of Grange at Magill Estate, adjacent to the Penfold wineworks in Adelaide Hills, the distinguished Kalimna Vineyard and other prestigious sites in Barossa Valley, assembled alongside the pick of fruit from Valley Clare. Cool, mild conditions prevailed during the growing season. Central to the long lived style of Grange is an extended term of maturation in an extravagant selection of exclusively new American oak hogsheads.
