South Africa for WSET: the Cape in four influences

South Africa is a Mediterranean climate that ought to be too warm for elegance, saved by a cold current, a persistent wind and some very old soils. It also has the tidiest appellation system on the New World side of the syllabus. This is an orientation; the regional drill belongs in your course materials and our app.

What WSET asks you to know

At Level 2, recognition: a warm Mediterranean climate at the southern tip of Africa, with Chenin Blanc as its most planted variety and Pinotage as its unique crossing.

At Level 3, you are expected to explain the moderating influences, navigate the Wine of Origin hierarchy, and place the main districts and wards against the styles they produce.

The framework

Three ideas carry most of the marks:

• Cold water and constant wind. The Benguela current runs cold water up the west coast, cooling sites near the Atlantic. The Cape Doctor, a strong south-easterly that blows through the growing season, lowers temperatures, dries the canopy and suppresses fungal disease, which is one reason organic viticulture is comparatively practical here. It can also damage shoots and disrupt flowering, so it is a mixed blessing rather than a pure benefit.
• Very old soils. The Cape has some of the oldest viticultural soils in use anywhere, weathered and low in nutrients. Low fertility restricts vigour, which favours concentration, and the granite, shale and sandstone-derived soils are frequently cited in producer literature and in exam answers about quality.
• Wine of Origin is a four-tier hierarchy. From largest to smallest: Geographical Unit, such as Western Cape, then Region, such as Coastal Region, then District, such as Stellenbosch, then Ward, such as Simonsberg-Stellenbosch. Unlike the EU model, the scheme certifies origin, vintage and variety claims rather than dictating how the wine must be made.

Within the Coastal Region, Stellenbosch is the classic address for Cabernet Sauvignon and Bordeaux blends, with mountain slopes giving cooler aspects. Paarl is warmer, and Swartland has become the reference for old bush-vine Chenin Blanc and Rhône varieties. Constantia, a ward near Cape Town, is historically significant for its sweet wine and now produces fine Sauvignon Blanc. Along the Cape South Coast, Elgin and Walker Bay, including the Hemel-en-Aarde wards, are the cool-climate sites for Chardonnay and Pinot Noir. Inland, Robertson in the Breede River Valley is warmer and lime-rich.

On grapes, Chenin Blanc is the most planted variety, long known locally as Steen, and the revival of old bush vines is the country's most important recent quality story. Pinotage is a crossing of Pinot Noir and Cinsaut created in South Africa in the 1920s and first bottled commercially in the 1960s. It divides opinion, and the heavily oaked, mocha-scented style sometimes called coffee Pinotage is a commercial category in its own right. A Cape Blend generally denotes a blend including a meaningful proportion of Pinotage.

How South Africa shows up in tasting

A Stellenbosch Cabernet reads deep ruby with ripe blackcurrant, cedar and a savoury, slightly dusty edge, medium-plus tannin and medium-plus acidity. A Swartland Chenin reads lemon to gold, with quince, yellow apple and honey over high acidity and a waxy texture. Pinotage is deep in colour with plum, bramble and a distinctive smoky, sometimes tarry note. For the climate vocabulary behind all of it, see climate types for WSET.

What to do next

Read South Africa alongside its principal varieties, Cabernet Sauvignon, Syrah and Shiraz and Sauvignon Blanc, then place it against the other Southern Hemisphere producers on the syllabus.
