The peak body for the country's wine industry says too much Australian wine on the market has affected the profitability of the Hunter's wine industry.
Hunter vignerons are holding an open forum today to discuss the industry's future.
Winemakers Federation of Australia chief executive Paul Evans says the oversupply of Australian wine has created fierce competition.
"Well for Hunter wine growers, they've got to compete with wines from all across Australia," he said.
"If there is an over-supply of course that competition increases.
"That competition is extremely fierce at the moment and that reduces margins and profitability for everybody."
Mr Evans says Hunter winemakers have been doing it tough, but emerging markets and a lowering of the Australian dollar may provide some relief.
"It's been a tough time for the industry," he said.
"The recent correction in the Australian dollar will help, and there's a lot of optimism around emerging markets such as China.
"But overall it's been a very challenging three or four, five years for the industry."
