John Duval produces Shiraz from the Barossa Valley, one of Australia's most celebrated regions for the variety. The winery's portfolio centers on single-varietal expressions that showcase the intensity and structure the region is known for. Ebenezer Shiraz, the flagship, has earned recognition from Decanter, Wine Spectator, Wine Enthusiast, and Wine Advocate. Annexus and Eligo Shiraz round out the core range, each offering distinct character from Barossa fruit. The winery's focus remains narrow and deliberate: Shiraz-driven wines that reflect the valley's warm climate and mature vineyards. Barossa Shiraz typically displays dark fruit density, peppery spice, and the ripeness that defines the region's signature style.
