Red Edge is the second oldest vineyard in Heathcote, having been planted in 1971. Two hectares of Shiraz and Cabernet Sauvignon were planted initially. Further plantings on adjacent blocks have seen the vineyard expand to 14 hectares under vine with some other classic European varieties also planted. The vineyard is planted on the famous Cambrian soil of Heathcote. The soil is vibrantly red, deep, free draining, mineral rich and eminently favourable to the vine, particularly Shiraz. The vines are all dry grown.

Since 2002, this drink now, fruit inspired Degree Shiraz blend is a contrast to the bigger, more tannic Red Edge Shiraz style.
