Josef Chromy Wines sales and marketing director David Milne said it was a credit to chief winemaker Jeremy Dineen, senior winemaker Ockie Myburgh, and the rest of the team behind the celebrated drop.

"They work tirelessly during vintage - it's 24 hours a day," he said.

"This is great recognition for the work that they're doing."

And Tasmania's wine-growing climate deserves some credit, too.

"The 2017 pinot just exhibits a really bright, red fruit character and lovely spice, and a firm and fine tannin," Mr Milne said.

"It's a very elegant, very pretty wine - it's a great expression of fruit.

"The winemakers don't overplay their hand: its flavours are complementary, and on this occasion they really stood out for the judges."

There were 2200 entries into the KPMG Sydney Royal Wine Show across all categories.

Mr Milne noted that four out of the five finalists in the pinot noir category - officially called the The Geoffrey Crundall Perpetual Trophy for Best Pinot Noir - were grown by Tasmanian businesses.

"It's a great example of the quality of Tasmanian wine," he said.

"Tasmania's climate lends itself to pinots that have great suppleness and great fruit profiles - they're very diverse.

"Certainly Tasmania is a centre of quality pinot noirs."

Tasmania didn't manage to nab the honour of best wine in show, however - that recognition went to the Yabby Lake 2017 Heathcote Estate Single Vineyard Shiraz.

The other top pinot noirs in the country in the opinion of the judges were: the Meadowbank Wines 2017, the Montalto 'merricks block' 2017 from Victoria, two Devil's Corner varieties - the 2017 Resolution and the 2017 Mt Amos - and the 2017 Tamar Ridge Estate.
