The Hunter business won the accolade for the fourth time at the 2019 International White Wine Challenge in London on Tuesday, UK time. McGuigan Wines is the only Australian winery in history to win the big gong four times. It bagged a total of 29 awards at the gala ceremony - four gold medals, 11 silver medals and 14 bronze medals.

Gold medals were awarded to the McGuigan Personal Reserve Shiraz 2017, McGuigan Shortlist Chardonnay 2015, McGuigan Shortlist Riesling 2013 and McGuigan Cellar Select Chardonnay 2017, with the latter also claiming two International Trophies for Eden Valley Riesling and NSW Chardonnay.

McGuigan Wines chief winemaker Neil McGuigan said he was proud of the winery's achievements at the competition.

"To have received the White Winemaker of the Year award four times in the last decade is unprecedented and extremely humbling," Mr McGuigan said.

"I am immensely proud of our achievements at this year's show, which are a testament to the commitment of our winemaking team.

"Every time an Australian wine is recognised at international wine competitions it puts Australia on the map and highlights the quality being produced. We continue to be incredibly honoured to represent Australia on the global stage.

"Award wins such as this reinforce the reputation of Australian wine and demonstrate we have truly earned our place among the world's best wines."

McGuigan Wines previously won the White Winemaker of the Year award in 2009, 2012 and 2013.
