James Dicey, of GrapeVision, said the botrytis levels were as low as he had seen.
"After a summer that delivered colder than normal temperatures, higher winds and higher rainfall, we were blessed with a very dry lead-up to vintage, which has resulted in incredibly low botrytis levels and very clean fruit when harvested,'' he said.
"We had a superb run through harvest with only one frost of note. We are about one week to 10 days later than normal in the Cromwell basin, but because of the differences in ripening times, wineries have been able to stagger the picking until perfect fruit ripeness.
"Some wineries are still picking sauvignon blanc. Riesling and pinot gris yields have been heavier than expected and pinot noir is a little bit down on expectations but tasting intensely flavoured.
"Initial looks at the wine under ferment is very very positive,'' he said.
VinPro chief winemaker Pete Bartle said he was surprised at the quality of the grapes after a cold summer.
Central Otago would "produce some great wine'' this year, he said.
