Inspired by the classic South Australian wines of the 1950s and 1960s, particularly Penfolds, the visionary Roman Bratasiuk, a former biochemist, bought the old Elysium winery at Blewitt Springs, near Clarendon in McLaren Vale. By chance, he found the nearby 10-acre Astralis Vineyard as a source of "as good as you can get" Shiraz. The vines were first planted in 1920 with 19th-century colonial vine stock derived from Chateau Reynella. Best known for the flagship wine Astralis Syrah, Clarendon Hills also produces a portfolio of single vineyard age-worthy Grenache & Syrah wines derived from 35 to 75-year-old dry-grown vines, from the Clarendon, Blewitt Springs, and Kangarilla sub-regions of McLaren Vale. Among the single vineyards of Cabernet and Merlot is the Domaine Clarendon BDX vineyard which is located within the Blewitt Springs sub-region of McLaren Vale, South Australia. All of the wines at Clarendon Hills are made by hand and are crafted using only natural processes and ingredients.
