The duo are first-time judges at the National Cool Climate Wine Show that is currently being held in Bathurst.

The role of a wine judge at the event is by invitation only, and this year’s panel are experts in their field.

Nick O'Leary, from Canberra vineyard Nick O'Leary Wines, has been a judge for the past seven years.

But, he said the job is a lot harder than it looks.

“It take a lot of concentration and because you’re spitting wine out, you’re not enjoying them fully. It’s not like drinking at home,” he said.

Each wine entered is tasted multiple times, and Mr O’Leary said judges do not always agree with each other on the points that should be awarded for each entry.

“There’s plenty of discussion so you’ve got to have your wits about you,” he said.

Judge Andrew Locke is the chief winemaker at Fleurieu Wines in the McLaren Vale Wine Region in South Australia and he agreed that it is difficult to judge so many wines.

“It’s actually quite gruelling, you have to think about everything. It’s like an eight or 10 hour exam. It’s quite tiring,” he said.

Mr Locke said each judge brings a different specialty to the role, including the types of wines they are experts in and their familiarisation with certain wine growing climatic conditions.

Judging commenced on Tuesday and on day one Mr O'Leary said sauvignon blanc entries were of a high standard.

“The 2016 sauvignon blancs class are pretty impressive, there’s a lot of solid commercial styles,” he said.

National Cool Climate Wine Show chief steward Mark Hayley said by late Wednesday a good number of gold medals had already been awarded.

“There’s 23 golds so far with one day left to go, with a big class of sparkling and shiraz to go tomorrow [Thursday],” he said.

“Four gold medals have been awarded in red alternate varietals out of a class of 23 which is pretty good.

“The chardonnay class came in with four gold medals, in particular the 2015 entries were great.”

This Friday, the annual public wine tasting event will be held at Bathurst Showground from 6-9pm with people invited to sample all of the wines entered.

Last year’s public tasting event attracted a record-breaking crowd of 320 people.

Ticket are $35 and can be purchased at the door on the night, however people are encouraged to pre-book through the Bathurst Visitor Information Centre.
