St Johns Brook sits in Margaret River, Western Australia's premier wine region, where Mediterranean climate and gravelly soils favour bold red wines and refined whites. The winery's Reserve lineup demonstrates the region's signature strengths: a Shiraz with the dark fruit intensity and structure Margaret River is known for, a Chardonnay that captures the region's ability to produce layered, complex whites, and a Cabernet Sauvignon built on the varietal's natural architecture. These wines have been assessed by Wine Enthusiast, Wine Advocate, Wine Spectator, Falstaff, and Decanter. The Reserve Shiraz, Reserve Chardonnay, and Reserve Cabernet Sauvignon form the core of the portfolio, each reflecting the terroir and winemaking precision expected from Margaret River's serious producers.
