What is the leading white grape variety grown in South Africa?

The leading white grape variety grown in South Africa is Chenin Blanc. This grape is highly adaptable to the country's diverse climates and is valued for its versatility in producing a wide range of wine styles, from dry to sweet and sparkling. South Africa has established a reputation for producing high-quality Chenin Blanc, often labeled as Steen, which is its historical name in the region. The grape thrives in various terroirs across the country, allowing winemakers to express different flavor profiles, making it a key player in the South African wine industry.

Sauvignon Blanc, Chardonnay, and Riesling are also significant grape varieties, but they do not surpass Chenin Blanc in terms of volume or significance in South Africa's vineyard landscape.
