But what has turned out to be a rather mild summer has set high expectations for the wine industry.

The moderate summer has been great for grapes which slowed ripening, Red Earth Estate Wines owner Ken Borchardt said.

"In our climate I think this year, after last year where we had so much disease and the vines were under a lot of stress from disease, this really slow ripening has been fantastic," he said.

After losing all their vines last year to powdery mildew, Mr Borchardt said the disease had not been at all prominent this year.

"We have had a strict spraying program just in case we did have that high humidity and extensive rain like we did last year, we were well prepared," Mr Borchardt said.

Mr Borchardt and his wife Christine have been able to expose their grapes to the sun this year without leaving them vulnerable to damage from the heat.

Due to an oversupply of grapes in Australia, Mr Borchardt culled some of his crop in respect for the industry to ensure a lasting future for both table and wine grapes.

"About three years ago when the wine industry asked growers to cut down, we actualle went through and took out about a hectare of them."

"There are too many grapes in Australia, there are too many vines in Australia and the production is too high," Mr Borchardt said about the reason behind it.

With grapes harvest soon to begin or in its early stages in some areas, the cool summer mornings are suggested by Mr Borchardt as the best time to pick the grapes as the heat can diminish their life expectancy after harvesting.
