Leasingham produces wines from South Australia's Clare Valley, a region celebrated for its cool-climate intensity and mineral precision. The winery's portfolio centers on two classical varietals: Riesling and Shiraz. The Classic Clare Riesling demonstrates the region's signature dry style—crisp, structured, and age-worthy. The Classic Clare Shiraz and Show Reserve Limited Release Shiraz showcase the darker, spice-driven character that defines the valley's Shiraz expression. These wines have been assessed by major critics including Wine Spectator, Wine Advocate, Decanter, Wine Enthusiast, and Falstaff. The winery's approach reflects Clare Valley's continental climate and slate-influenced soils, which impart distinctive mineral notes and tannin architecture to both red and white wines.
