Clarendon Hills produces Shiraz and Grenache from South Australia, a region celebrated for its warm climate and ripe fruit expression. The winery's portfolio centers on two flagship Syrahs: Astralis and Onkaparinga Syrah, both of which have earned recognition from Wine Enthusiast, Wine Advocate, Wine Spectator, Falstaff, and Decanter. Onkaparinga Grenache rounds out the core range. These wines reflect the intensity and structure characteristic of South Australian Shiraz, where the variety achieves full phenolic ripeness and dense fruit concentration. The region's maritime influences and varied terroirs allow for wines of both power and definition.
