Stellenbosch is one of the oldest wine-producing regions in South Africa. Together with the valleys of Paarl and Franschhoek, it forms the Cape Winelands, the largest of the two main wine regions in South Africa. Most of the vineyards are located at an altitude of about 100 meters above sea level.
Climate
Stellenbosch enjoys a Mediterranean climate with generally hot and dry summers and cold, wet winters. Summers begin with windy days. The wind helps to alleviate the high temperatures of the season. When this wind subsides, temperatures can reach 40º C. In autumn, the weather is more pleasant, with moderate temperatures, and it brings the first rains. Winter, on the other hand, is characterized by cold fronts, strong northwesterly winds, and torrential rains, followed by scattered showers interspersed with warmer, sunnier days. Finally, spring begins with cold and wet weather, although the fronts gradually weaken. Little by little, the weather becomes warmer and drier.
Soil
The terrain of Stellenbosch is composed of a variety of soils ranging from the alluvial and well-drained ones on the slopes to the decomposed granitic soils of the valley.
