Orange Wine Show | Perils of tasting 100 wines a day | Photos

But, being a wine show judge does come with a serious occupational hazard - and it's not alcoholism.

Orange Wine Show chief steward Will Rikard-Bell says the judges have to look after their teeth.

"[Wine], it's acidic, it can strip the enamel off your teeth," he said.

"It can be arduous, it sounds like a great job, but by the end of the day they are screaming for a glass of milk."

He said the judges needed to regularly rinse out their mouths with water and keep their palate in check with dry biscuits and cheese.

Judging for the 2019 Orange Wine Show started on Wednesday.

Eight judges, spread over two panels, will share in the tasting of 340 wines over a day and a half.

He said the judges were a mix of winemakers, sommeliers and people within the wine industry from all over Australia.

Mr Rikard-Bell said he was expecting this year's wines would be top quality after favourable grape growing seasons.

"The wines will be the [20]17's, 18s and 19s which were pretty warm, dry years," he said.

Mr Rikard-Bell said those conditions promoted a greater concentration of flavour in the wine and reduced the risk of disease compared to wet years.

The awards will be presented at a lunchtime ceremony at the Hotel Canobolas on Friday, October 11.

The Orange Wine Show Tasting and Masterclass, where you can taste the show wines, will open the Orange Wine Festival on Friday October 18.

Tickets to the tasting and masterclass cost $80.
