It has returned home from the South Coast Wine Show with a swag of trophies and medals boosting its prize winning tally to more than 240 trophies and medals at regional, national and international wine shows since the first vintage in 2005.

In fact, only six gold medals were awarded across 19 classes at the show and Tertini Wines received three of them.

The recently released 2009 pinot noir proved to be the star of the 2012 South Coast Wine Show, winning a gold medal and trophies for Best Pinot Noir, Best Red Wine of the Show and Best Wine from the Southern Highlands.

The 2008 Tertini riesling continued the winery's extraordinary track record with this grape variety by winning a gold medal and trophy for the Best Riesling. This riesling has now won nine gold medals, including at the International Riesling Challenge.

The 2009 Tertini Reserve Noble Riesling also seems to be destined for further show success, winning a gold medal at its very first wine show.

Tertini Wines sales manager Robert Kay said the Tertini team was "absolutely delighted" with the result.

"The judges at this wine show are highly respected, with plenty of national and international experience," he said.

"The chief judge emphasised in his summation that three of the wines, including the 2009 Tertini pinot noir and 2008 Tertini riesling, are truly world class."

The 2009 pinot noir had won four gold medals in recent months.

"This includes the 2011 National Wine Show, Australia's only best-of-the-best wine show where a wine has to win gold or silver at another major wine show to be eligible to enter," he said.

"Like riesling, pinot noir is a variety that is well suited to the cool climate of the Southern Highlands and it seems to be doing particularly well at Tertini's Yaraandoo vineyard near Berrima.

"Pinot noir is a challenging variety that is very sensitive to climate, soils and vine age, so it is particularly pleasing to see these results from such young vines.

"The success points to a great future for pinot noir from Yaraandoo and the rest of the Southern Highlands."

Mr Kay said Tertini was committed to producing the best quality fruit possible at Yaraandoo, with hand pruning, regular soil testing, careful canopy management, low cropping and hand picking.

"Then we hand over the fruit to our winemaker, Jonathan Holgate, with the expectation that he will craft an award-winning wine, which he has done brilliantly and consistently," he said.

Tertini's cellar door is on Kells Creek Road, off Wombeyan Caves Road, Mittagong, and is open from 10am to 5pm from Thursday to Monday.
