It will be 30 years this year since the first modern-day wine made in the Alexandra basin was sold.
In his new book Latitude 45.15S - among the world's southernmost vineyards journalist, Otago Daily Times columnist, bed and breakfast co-owner and author Ric Oram said 2400 bottles of Black Ridge gewurztraminer and riesling and 2000 bottles of assorted William Hill varieties were sold in 1988.
Bill Grant, of William Hill vineyard, and Verdun Burgess, of Black Ridge, sent their grapes to Rippon vineyard in Wanaka to be made into wine by Tony Bish.
Mr Oram also believes this year is possibly the 150th anniversary of the first wine made in Central Otago, in Clyde, using grapes grown by Frenchman Jean Feraud.
However, as nothing was documented on the planting and first vintage, it was just an estimate.
