Frankland Estate operates in the Frankland River subregion of Great Southern, Western Australia's cool-climate wine country. The winery produces wines across multiple varietals, with particular strength in Shiraz, Mourvèdre, and Riesling. The SmithCullam Shiraz has drawn attention from major critics including Wine Advocate, Wine Enthusiast, Wine Spectator, Decanter, and Falstaff. The Isolation Ridge Mourvèdre and Smith Cullam Riesling round out the portfolio, each receiving assessment from the same prestige publications. Great Southern's maritime influence and diurnal temperature swings create conditions suited to both structured reds and aromatic whites, characteristics evident across the winery's range.
