According to Andrew Teubes in History of Rootstocks in South Africa, 101-14 Mgt is the traditional rootstock of the coastal area of Stellenbosch. He says the deep red soils on the slopes of the Helderberg and Simonsberg (Hutton, Clovelly and Oakleaf soil forms) are very well-suited for good performance of 101-14. Here, it induces moderate vigour and early maturity of late-ripening vigorous red wine grape varieties like Cabernet Sauvignon.

99 Richter was popular through the 90’s, but has been replaced by 110 Richter for drought resistance. It’s welcomed because of its slow rate of early growth, a necessary characteristic because time is needed to set the right structure and form for the plant.


Various clones are planted throughout the region depending on soil types, drainage, climate and style. Each vineyard is unique and clones that work on that specific site are usually what is planted. It’s all about ‘giving yourself options’ says the team at Ernie Els, who planted clone garden to monitor what works best in the region. Clones like CS163, CS169, CS46, CS15, CS338, CS37 (one they believe is underutilised by Stellenbosch growers because of the beautiful fruit and tannin structure it delivers) are also readily planted in the region. The most planted clone is CS46 for its consistent good quality.
