Battle of Bosworth draws from McLaren Vale, the warm heart of South Australia's Fleurieu Peninsula, where Shiraz thrives in Mediterranean conditions. The winery's portfolio centers on this signature variety—a grape that finds particular expression in the region's gravelly soils and generous sunshine. The White Boar, a Cabernet-Shiraz blend, and the Puritan Shiraz represent the core of the range, wines that have drawn attention from Wine Advocate, Wine Enthusiast, Decanter, Wine Spectator, and Falstaff. McLaren Vale Shiraz characteristically shows dark fruit density, peppery spice, and the structural weight that defines the region's best examples. The winery's focus remains on these core varieties and their expression of place.
