Sister's Run operates in McLaren Vale, the warm-climate heart of South Australia's Fleurieu Peninsula. The winery focuses on Shiraz and Grenache—varieties that thrive in the region's Mediterranean conditions—alongside Cabernet Sauvignon and the traditional southern Rhône blend component Mataro. Cow's Corner Grenache-Shiraz-Mataro anchors the portfolio, a wine that reflects McLaren Vale's signature ripeness and structure. Epiphany Shiraz and Old Testament Cabernet Sauvignon round out the core range. Decanter, Wine Advocate, Wine Spectator, and Wine Enthusiast have all assessed the winery's output, offering independent perspective on its approach to these classic varietals in one of Australia's most established wine regions.
