Wynns operates in Coonawarra, the Limestone Coast's most celebrated wine region, where terra rossa soil and cool maritime influence shape wines of distinctive character. The winery's portfolio centers on Cabernet Sauvignon and Shiraz, varieties that thrive in this terroir. Johnson's Block Single Vineyard Cabernet Sauvignon represents the pinnacle of the range, while V & A Lane Shiraz and the Cabernet-Shiraz blend demonstrate the region's capacity for structured, age-worthy reds. These wines have been assessed by Wine Advocate, Wine Spectator, Wine Enthusiast, Decanter, and Falstaff. Coonawarra's cool climate and limestone-rich earth produce Cabernets with the structure and complexity the region is known for, alongside Shiraz wines marked by peppery spice and dark fruit depth.
