The Coastal Region is the most important wine-producing region of South Africa. A Mediterranean climate helps to ripen the grapes during the day whereas the cold nights ensure that the flavor profiles and the acidity of the wines are maintained. A plethora of grape varieties thrive in the Coastal Region's terroir, with all the major popular grape varieties making quality wines. Chenin Blanc (locally known as Steen) and Pinotage perform exceptionally well.
