Only three vineyards in New South Wales have been included in the listing and Printhie is the only finalist from the Orange wine region.

Vineyard of the Year is new national initiative of by the Young Gun of Wine team, which usually focuses on the Best Winemaker of the Year.

From more than 6000 grape growers, the judges selected the final 50 from those who demonstrated a commitment to innovation and sustainability that resulted in improved vine health and wine quality.

Printhie Wines was shortlisted because of its focus on innovation and the use of air sampling technology to detect disease spores, which can be used to monitor vine health and reduce reliance on traditional methods of vineyard maintenance.

Printhie Wines viticulturalist Charlie Simons said the top 50 selection was testament to Printhie's aim to constantly improve the environmental sustainability of the vineyards.

"We're completely focused on producing premium quality wine and to do that we need to have the best vineyards," Mr Simons said.

Printhie Wines is a family owned winery and cellar door where brothers Ed and Dave Swift manage the operations and Drew Tuckwell is in charge of winemaking.

To judge the Top 50 Vineyard awards, a group of leading experts on viticulture, agronomy and sustainability were enlisted to personally review all the applicants.

Dr Mary Cole, Dr Mardi Longbottom, Mark Walpole, Dr Irina Santiago-Brown, Dr Peter Dry AM and Max Allen selected the top 50.

"Among the group of 50, there is a trend of going away from scheduled sprays and many of them are choosing to use less harmful chemicals to try to create a healthier environment for a more self-balanced vineyard, with beneficial insects, healthier and more alive soil, as well as being healthier for the people who work there," Dr Santiago-Brown said.

"Many innovations are being used to reach this end... from more suitable grape varieties, to state-of-the-art technology to measure vine and soil status in order to make better decisions."

The judges will visit the shortlisted vineyards and they will award four trophies with the winners to be announced in February 2021.
