But Oyster Bay has been no overnight international success, Delegat is quick to point out. "It was launched in 1990 and we started building it in global markets 25 years ago," Delegat says, with this global vision still a key part of the company's philosophy. As an aside he tells me that Oyster Bay Marlborough Pinot Noir is the leading New Zealand pinot noir globally.
Though many wineries preach a philosophy of product quality, Delegat has a different perspective. "Wine quality is a given," Delegat says. All wines have that now, but consumers also seek an emotional reward in their purchase. We did this through the way we communicated about the Oyster Bay brand, which also made it a powerful business proposition for retailers."
Consistency has been crucial to its success, says Delegat, who scoffs at wineries that try to innovate through "tinkering with labels" or create new expressions of sauvignon blanc using techniques such as barrel fermentation. He was also not convinced by the move to plant syrah in the Gimblett Gravels.
"We thought we'd rather make shiraz (syrah) in the Barossa Valley. We'd been contemplating this seriously for the last 18 months, which was behind our decision to purchase Barossa Vineyard Estates."
Although Australian enterprises have had wine interests in New Zealand over the years, it's rare to see this happen the other way around. Delegat's also takes its stake in prime Aussie shiraz territory at a time of growing hostility from winemakers in Australia. Some have been openly critical of New Zealand sauvignon blanc, which has diverted a sizeable portion of Australia's domestic market away from home-grown products.
"I can't understand the sense in bagging what you don't make yourself," says Delegat of this wave of Kiwi-bashing. "They don't have the cool climate conducive to making it, or unique character of Marlborough sauvignon. It's just sour grapes."
Despite now becoming a producer of shiraz, Delegat doesn't think sauvignon blanc has had its day, in Australia or elsewhere.
"New Zealand accounts for 50 per cent of the sauvignon blanc sold in the UK. Just imagine if we accounted for 50 per cent of all the sauvignon blanc sold in the world. In its present style I see no sunset for sauvignon blanc."
