Smith & Hooper operates in the Limestone Coast, South Australia's maritime-influenced region known for cool-climate precision and mineral-driven wines. The winery's portfolio centers on Bordeaux varieties and Shiraz, with the Hundred Of Joanna—a Merlot, Cabernet Sauvignon, and Shiraz blend—as its flagship. This wine has drawn assessment from Wine Enthusiast, Wine Spectator, Wine Advocate, and Falstaff. The winery also produces a varietal Merlot and a Merlot-Cabernet Sauvignon blend. Limestone Coast's chalky soils and cool growing season create conditions for wines with structure and acidity, characteristics evident across Smith & Hooper's range. The region's maritime climate moderates ripening, allowing for complexity in both single varietals and blended expressions.
