Vineyard staff were put to work yesterday on Quartz Reef's 30ha of fields in Bendigo.
Following a historic early season start in 2018, Quartz Reef winemaker Rudi Bauer said yesterday's first day was more "typical''.
"Sparkling wine is quite early. Our main harvest will be March 20, which is quite late compared to the rest of New Zealand.''
Vinewise viticulturist Grant Rolston said the regular rainfall in spring had led to more stability for winegrowers.
"The wet spring has helped us in many ways because it's taken the pressure off irrigation.
"You compare it to last year, where there was high pressure on irrigation resources, to this season, which is one of the lowest seasons of irrigation usage in many years.''
As things got under way, the issue of employment remained an early-season consideration for Central Otago growers, Mr Rolston said.
"You never really know until you get into the season proper what the employment situation is going to be like.''
About 20 vineyard staff toiled away at the Bendigo vineyard during the first day.
"We're hoping to eventually have a staff of about 40 as we get through the season,'' Mr Bauer said.
The local product has started turning heads internationally, as 40 Masters of Wine members visited Central Otago during the week.
Mr Bauer said the members "were very impressed with the region''.
Central Otago Winegrowers Association acting president James Dicey said it "was looking positive'' as the local product forged a high reputation.
"By working together, we're helping develop the reputation of the region.
"These [Masters of Wine members] are from around the world.
"They want to understand what's driving the great wine that is being made here.''
