Rockford is in the South Barossa Valley. It was founded and is still owned by Robert O’Callaghan, whose grandparents on both sides of his family were grape growers. In 1971 O’Callaghan bought five acres and a 19th century cottage in the heart of Barossa Valley. Though acclaimed winemaker Chris Ringland made the estate’s wines in the 1990s, today O’Callaghan and Ben Radford share winemaking. Australian wine writer James Halliday has written that “Rockford can only be described as an icon…It has a devoted band of customers who buy most of the wine through the cellar door or mail order.”
