In each vintage worthy of making iconic wines, Wynns produces two flagship wines: John Riddoch Cabernet Sauvignon and Michael Shiraz. Michael Shiraz is Wynns Coonawarra Estate’s best-of-vintage Shiraz. The first Michael (once called Michael Hermitage) was a one-off from the 1955 vintage, made after proprietor David Wynn noticed the outstanding quality of the wine from two particular barrels. He ordered that these two barrels be bottled separately and this wine – named after Wynn’s young son – is a legend of the Australian wine industry. Original bottles still offer a great wine experience. Revived with the superb 1990 vintage, the fruit used for the Michael Shiraz comes from the best vineyard sites in Coonawarra. It is only made in years when the grapes are of extraordinarily high quality.

First made in 1982, the John Riddoch Cabernet Sauvignon was conceived as a flagship wine for the Wynns portfolio. The wine honours pasturalist and parliamentarian, John Riddoch, who was the largest land-owner in South Australia’s south-east corner. With his brother George, the two owned the freehold of more than 70 000 acres. Wynns John Riddoch Cabernet Sauvignon is made in small quantities from the best available fruit grown on the estate’s extensive Cabernet plantings. It has become a definitive Coonawarra Cabernet Sauvignon, made only in years when grapes of extraordinarily high quality are available - less than one percent of Wynns' top Cabernet grapes.
