Fonthill draws from McLaren Vale, the warm maritime region of South Australia's Fleurieu Peninsula known for bold reds and distinctive white varietals. The winery's portfolio centers on Shiraz, the region's signature grape, alongside Grenache and Verdelho—a white varietal that thrives in McLaren Vale's temperate coastal climate. The McLaren Vale Silk Shiraz, rated by Wine Advocate, Wine Spectator, and Wine Enthusiast, anchors the range with the depth and structure characteristic of the region's best expressions. Complementing it are the McLaren Vale Dust Of Ages Grenache, which captures the spiced, earthy character of the variety, and the McLaren Vale Sea Air Verdelho, a crisp white that reflects the peninsula's maritime influence. Each wine reflects the terroir of one of Australia's most established wine regions.
