Marquis Philips 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 and gravelly soils. Shiraz 9, the flagship, demonstrates the depth and structure McLaren Vale Shiraz can achieve, earning recognition from Wine Spectator, Wine Advocate, Decanter, Wine Enthusiast, and Falstaff. The Grenache expresses the lighter, spice-forward character the variety brings to the region, while Sarah's Blend—a Shiraz, Merlot, and Cabernet Sauvignon composition—shows the winery's approach to blending across the classic red palette. These wines reflect McLaren Vale's signature style: ripe, full-bodied reds with the balance that cool nights and maritime influence provide.
