Michael Shiraz is Wynns Coonawarra Estates best-of-vintage Shiraz. The fruit used for this wine comes from the best vineyard sites in Coonawarra and is only made in years when the best quality fruit is available. The first Michael (then 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 and ordered them to be bottled separately.
