Different climate zones are used to ensure a wide selection of quality grapes. Firstly, the south-easterly slopes on the Tygerberg Hills, Durbanville and the south-westerly slopes of Devon Valley, Stellenbosch are both characterized with high clay content soils resulting in excellent water retention. The
cool breeze from the cold Atlantic Ocean also ensures healthy grapes. The northern facing
slope on the Helderberg basin in the Somerset West region ensures excellent sun exposure and fertile soil to enable stabile growing conditions.
