Kershaw operates in Elgin, a cool-climate pocket of the Cape South Coast in Western Cape. The winery focuses on Chardonnay, a variety that thrives in Elgin's maritime conditions and chalky soils. Its portfolio includes the Deconstructed Groenland Bokkeveld Shale CY548 Chardonnay, the GPS Series Lower Duivenhoks River Chardonnay, and a Clonal Selection bottling—each expressing the region's mineral character and precision. These wines have been assessed by Wine Advocate, Decanter, and Wine Spectator, reflecting the technical rigor evident in their production. Kershaw's approach emphasizes terroir specificity and varietal focus, with each release anchored to distinct vineyard sites and clonal choices within Elgin's complex geology.
