Syrah production. This made Shiraz the most planted variety in Australia and Australia the world's second largest Syrah/Shiraz grower, after France. Victorian regions include Heathcote, roughly 1.5 hours north of Melbourne. Cooler climate regions such as Western Australia's Margaret River produce Shiraz with marginally less alcohol content and often in a more traditional French style. A well-known example of the Shiraz grape in Australian viticulture is the Penfolds "Grange". This wine was created by winemaker Max Schubert in 1951 and has a reputation for aging well. The Penfolds Grange is predominantly Shiraz but often includes a small quantity of Cabernet Sauvignon.

Rougier, an ampelographer writing for Pierre Viala and Victor Vermorel's catalog of grape varieties, determined that the two were separate varieties with Étraire de la Dui likely being an offspring of Persan. Over a 100 years later, DNA testing conducted by Swiss geneticist José Vouillamoz "strongly suggested" that there was, indeed, a parent-offspring link between Persan and Étraire de la Dui but in what direction (i.e. who is the parent and who is the offspring) is not yet known. Other varieties that Persan has been confused with over the years include Mondeuse noire, Syrah and
