The cooler climate wine regions of southern Victoria and South Australia are already suffering under drought conditions but now clear skies have contibuted to a series of freezing nights and, since late September, 3500 hectares of vineyards have been damaged by frost across eleven Victorian wine regions according to the Victorian Wine Industry Association.
Average crop damage is 60 per cent although some vineyards have lost their entire crop. The worst affected areas are Heathcote, the King and Alpine Valleys and Goulburn Valley. A late frost in the Yarra Valley is also believed to have damaged up to 60 per cent of their crop.
The Coonawarra region has also suffered from two weeks of frosts ravaging at least 30 per cent of the vines.
