South African wine and Chenin blanc. The cool climate Overberg region has been the site of the most recent interest and development in the South African wine industry, particularly with increased plantings of Chardonnay and Pinot noir. The entire area received very little attention until the late 20th century and was not even classified in 1973 within the original Wine of Origins programme. The maritime climate of Walker Bay and the cool, higher elevation vineyards of Elgin located east of Cape Town, have had success producing these varietals as well as Sauvignon blanc. The "Klein Karoo" region (meaning Little Karoo) has a semi-desert
