South Africa Flashcards
What happened in 1994 in South Africa?
African National Congress won the first democratic elections
Which organisation controlled the South African wine industry prior to the 1990s?
KWV co-op had regulatory powers determining production volumes and prices
What were the most planted grape varieties in South Africa prior to the 1990s? What were these used for?
Highly productive varieties:
Chenin Blanc
Colombard
Cinsault
Most wine was destined for the brandy industry
What percentage of plantings in South Africa are black?
45%
How much South African wine was exported in 2018?
420 million hl
South African vineyards are found between what latitudes?
33 to 35 degrees south
What is the general climate in South Africa?
Warm mediterranean
What is the Benguela current?
- Cool current flowing north up the African coast
- Mingles with warmer Agulhas current from Indian ocean
- Lowers water temperatures between Cape Town and Cape Agulhas
- Large temperature difference between coast and land causes regular beneficial fogs and coastal breezes
What is the Cape Doctor?
What effects can it have on vineyards?
- South easterly spring / summer wind
- Extends the impact of the Benguela current
- Reduces disease pressure
- Brings occasional rain to the south coast
- Can damage leaves (affecting photosynthesis and ripeness)
- Can affect flowering and fruit set, reducing yields
What is the average rainfall in Stellenbosch?
700mm (adequate)
When does most rain fall in South Africa?
May to August
Why is rainfall north of the Western Cape lower than further south?
- Decreased impact of the Benguela current
- Protection from the mountains following the coastline
Why can winter freeze be an issue in some areas of South Africa?
Lack of consistent winter freeze can cause issues with vines failing to rest over winter
What is the most planted grape in South Africa?
Chenin Blanc
Did area under vine in South Africa increase or decrease by 8% from 2008 to 2018?
Decreased
Pinotage is a crossing of which two grapes?
Pinot Noir
Cinsault
Pinotage is ____ budding and moderately susceptible to ______ ____.
It makes vines with ____ berries and wines with ____ alcohol and ____ colour.
Early budding Moderately susceptible to fungal diseases Small berries High alcohol Deep colour
What do winemakers need to avoid to make better quality Pinotage?
Avoid water stress and high fermentation temperatures
Name and describe the three main soil types in Western Cape
SOILS DERIVED FROM TABLE MOUNTAIN SANDSTONE
- Sandy, low nutrients, low water retention
- Irrigation and fertilisation may be needed
SOILS DERIVED FROM GRANITE
- Foothill slopes of mountains and hilly areas
- Good water retention, potential for dry farming
SOILS DERIVED FROM SHALE
- Good nutrient levels and water retention
- Potential for dry farming
Which two soil types in Western Cape have potential for dry farming?
Soils derived from granite and shale
Are most Cape soils overly acidic or alkali?
What effect does this have on the vines?
What can be done to compensate?
Excessively acidic
Inhibits the vine from taking up nutrients
Lime adjustments are needed to correct the pH and make it suitable for vine growth
Is vine density in South Africa low or high?
Typically low, with large vines carrying more fruit
Some higher quality producers work with closer spacing
South Africa has a legacy of plants with viral diseases - which two in particular?
What is the effect of this?
Fanleaf and leafroll
Reduced yield and added cost where badly affected vineyards need to be replanted.
This is being tackled by planting virus tested vines, but this also adds cost
What is the most common fungal disease in South Africa?
Powdery Mildew
What type of vine training is common in South Africa?
Cordon with VSP with a fruiting wire at 2.4m for ease of pruning.
Short spur pruning is common (can be mechanised) but most is done by hand due to large availability of labour
What is the Integrated Production of Wine system (IPW)?
A very detailed system introduced in 1998
Governs all aspects of growing and winemaking from carbon emissions, to staff training and conservation of soils rivers and wetlands
What percentage of South African wine export producers adhere to the IPW system?
90%
Explain the typical winemaking choices for inexpensive South African Chenin Blanc
- High yields
- Spray against disease
- Minimal sorting of fruit
- May be blended with up to 15% of another grape
- Acidification
- No MLF
- Cultured yeasts
- Cool ferment in stainless steel / cement
- Short ageing in old oak or steel
- Addition of oak flavours
- Add residual sugar (concentrated grape must)
- Stabilise, fine and filter
- Early release
- Bulk transport
- Bottled @ destination market
Explain the typical winemaking choices for quality South African Chenin Blanc
- Low yields
- Often old dry farmed bush vines
- Sometimes small amount of botrytis
- Careful sorting
- Avoid MLF
- Ambient yeasts more likely
- Cool ferment in inert vessels
- Increased use of eggs and amphorae
- 3 to 9 months on lees
- Battonage for richer style
- No sugar adjustments
- Stabilise with light fining and filtration as required
- Bottled in South Africa
Give a typical tasting note for a South African Chenin Blanc
Medium to pronounced intensity fruit Ripe, yellow apple, peach, tropical notes High acidity Medium alcohol Medium body
(Some may have vanilla and toast from new oak)
Explain the typical winemaking choices for quality South African Pinotage
- Low yields
- Careful sorting
- Cold soak prior to crushing to improve colour extraction
- Pump overs and punch downs at the start of extraction (lower alcohol means less tannin is extracted)
- Post fermentation maceration varies: lighter style typically will avoid maceration, while a traditional style will stay on skins 3 to 5 days
- 12 to 15 months ageing in French oak (typically 50% new, although oak used is falling)
- Released 2 years after vintage
Give a tasting note for a traditional South African Pinotage.
How will a lighter style differ?
Deep ruby Red plum and blackberry fruit High tannin Full body High alcohol
Lighter styles: source from cooler sites and picked earlier, no post fermentation maceration
Medium ruby
Red fruited
Medium tannins
What sort of ageing would you expect for an inexpensive South African Pinotage?
Age in stainless steel or old oak
Staves or chips may be added to give oak flavour
Wines are released early - 6 to 12 months after vintage
What is a White Cape blend?
Typically a Chenin dominant blend but with white Rhone grapes, Semillon, Sauvignon Blanc or Chardonnay
Most South African wine regions grow “the big six” varieties - what are these?
Chenin Blanc Sauvignon Blanc Chardonnay Cabernet Sauvignon Shiraz Pinotage
How do red Bordeaux blends differ from Red Cape blends?
Red Cape blend is a broader category for blends with a significant proportion of Pinotage and / or Rhone varieties
What are the four levels of the South African Wine of Origin system?
