Which of the following is NOT a primary white cultivar in South Africa?

In the context of South African viticulture, Sauvignon Blanc, Chardonnay, and Semillon are all recognized as significant white wine cultivars contributing to the country’s diverse wine offerings. These varietals are widely planted and celebrated for their unique expressions in various regions of South Africa, thanks to favorable climates and soil types, as well as a growing reputation for quality wine production.

Malbec, on the other hand, is primarily known as a red grape variety, originally hailing from France but more famously associated with Argentina. While some growers may experiment with Malbec in white wine production, it is not a primary white cultivar, nor is it widely recognized for producing white wines in South Africa. This makes it clear why Malbec does not belong to the group of primary white cultivars in the South African wine industry.
