South Africa Flashcards
Climate
Where is it located, what is the climate, and what are climatic influences?
- Latitude: 32-35°S (comparable to California)
- Warm Mediterranean climate
- Influenced by Western Cape’s many mountain ranges, slopes and aspects
- Proximity to the ocean (cooling effect)
- Cold north-flowing Benguela current
- Large temp difference between ocean and land causes regular beneficial coastal fog and cooling breezes
- Cape Doctor during spring and summer
Climate
Comment on diseases and hazards
- Low disease pressure due to winds (cape doctor)
- Winds can damage leaves, affect photosynthesis and flowering and fruit set
- Spring frost can be a problem
Climate
What is the avg. rainfall, when does it mainly fall and comment on irrigation
- 700mm on avg. in Stellenbosch
- Rain falls mainly between May and August
- Gets less in the north (less impact of Benguela current and more protection through mountains)
- Irrigation or promotion of old vines is essential in the drier areas
- Drought is an issue
- Access to water is a problem
Grape varieties
What 8 varieties account for 80% of plantings? (in descending order)

Grape varieties
What is the typical style of wine from Colombard? (aromatic, acidity, how used)
- Neutral

- Early budding (but spring frost rarely a problem in warmer parts)
- Only moderately susceptible to fungal diseases
Grape varieties - Pinotage
What are the characteristics? (color, potential alcohol)
- Deep color
- Reaches high sugar levels in small berries -> potentially high alcohol
Grape varieties - Pinotage
What is the typical quality of wine that can be produced from this grape?
- Past: reputation for poor quality
- Recently: Improvement in quality through better vineyard practice (e.g. avoiding water stress) and better winemaking (avoiding overly high fermentation temperatures)
Soils and Vineyard Management
What are the different soil types? Is it rather uniform or complex?
- Very variable and complex
- Table Mountain sandstone: sandy, low nutrient and low water-retention properties
- Granite: foothill slopes of mountains and in hilly areas. Good water-retention properties (dry-farming possible)
