Ramsay said about 20 per cent of the original stock had been bottled, with about 360 barrels still left.
"We need to think about production coming in as stocks wind down," he said.
Ideally, barley and malt ingredients would be sourced from around the South Island, Ramsay said.
He said the deal with Woolworths in Australia, which operates four separate liquor chain stores, was likely to account for half of the remaining stock in sales in the next four to six years.
He understood that for every A$1 spent on off-premise liquor purchases in Australia, Woolworths had the equivalent of a 38c (or 38 per cent) market share. Australians were paying A$89 ($116) for a bottle of Dunedin DoubleWood, with the New Zealand whisky becoming popular with expatriates in Queensland, Sydney and Perth. In New Zealand the DoubleWood price was $79.
The single malts include Milford, 1987, (cask strength) 1988 and South Island Single Malt, and blends the Water of Leith and Dunedin DoubleWood.
Ramsay said the United Kingdom's second largest distributor, Gordon & MacPhail, was interested in stocking its New Zealand-origin whisky, which in general had been boosted by the brand of New Zealand moving up the global rankings, from seventh to fourth recently and now ahead of Australia.
Retail sales and tastings have been established in a seven-day cellar door outlet in the Loan & Mercantile in Oamaru's historic precinct and a part-time outlet in Dunedin's railway station, timed for cruise ship visits.
The syndicate paid an undisclosed sum for the whisky assets of a company which had been placed in receivership in February 2010 by South Canterbury Finance, owing an estimated $3 million.
