Australia Flashcards
Who brought European vines to Australia? What kind of wines were first produced?
- James Busby in 1830.
- Fortified wines from Muscat Gordo Blanco (Alexandria). Mostly for the domestic market. It stopped after WWII as many Europeans arrived in Australia demanding more dry wines.
How Australia dominated the export market in the 80s?
- Orlando (Jacobs Creek), Lendemans, Hardys and Penfolds brought stainless steel and temperature control from the 50s to modernise the industry.
- Marketing based on labelling varietals and tasting notes on the back label.
Why since 2000 plantings have fallen back?
- Oversupply of inexpensive to mid-priced wines.
- Other non-European countries copied the Australian marketing model.
- Strength of Australian dollar after the crisis of 2008 made wines more expensive.
- Series of serious droughts.
Focus has moved from inexpensive to premium.
In which part of Australia viticulture is present?
South-east corner. 30-37 latitude.
Most of the country is desert or rainforest.
What are the two main climatic influences of Australia?
- Coastal influences (Indian/Southern Ocean). As Australia is mostly flat breezes can reach more inland. Some of those winds helps also with spring frost in cooler areas.
- Great Dividing Range mountains. They offer aspect, altitude and rain shadow effects (problems of drought). They also protect from tropical weather systems coming from the Pacific.
Main problems/hazards/diseases in Australia.
- Drought.
- High vigour.
- Soil salinity.
- Bush fires.
- Birds and kangaroos.
Lack of water remedies in Australia. Where irrigation water is coming from?
- Rivers of the Murray-Darling Basin.
- Winter rainfall stored in dams.
- Underground water sources.
- Recycled wastewater from cities.
Systems are mostly drip.
How vine vigour is reduced in Australia?
- Old vines (naturally produce less).
- Divided canopy systems: Scott-Henry and Smart-Dyson.
Advantages of machine and hand-picking during harvest in Australia.
Machine:
1. Less labour cost.
2. Can cover large areas in short time.
3. Harvesting at night is easier.
Hand:
1. Better selection.
2. Limit grape splitting.
3. Maintain whole bunches.
Soil salinity in Australia. Why is it a problem and what are the remedies?
Saline soils can make it difficult for the vine to collect water. It happens because there’s not enough water to carry away the salts.
Use suitable rootstocks and change irrigation patterns.
Natural pests and remedies in Australia.
- Birds (netting).
- Kangaroos (no solution).
Does Australia has phylloxera?
Strict quarantine and biosecurity laws permit high ungrafted phylloxera-free old vines.
Rootstocks are still used to combat the salinity and acidity of the soils or prevent a phylloxera outbreak.
Main varieties planted in Australia.
- Shiraz (25%).
- Chardonnay (20%).
- Cabernet Sauvignon (15%).
- Merlot (5%).
Also Sauvignon Blanc, Pinot Gris, Muscat Gordo Blanc, Semillon, Colombard, Pinot Noir, Riesling.
Alternative varieties (mostly around the Mediterranean) are rising such as Tempranillo, Sangiovese, Fiano, Assyrtiko.
Function of Shiraz in Bordeaux blends in Australia.
Replaces Merlot.
Gi system of Australia.
- Zones - larger areas that can cover an entire state. Also Adelaide “super zone” (includes Barossa, Mount Lofty Ranges and Fleurieu).
- Regions - smaller areas (e.g. Coonawarra). Needs to have distinct qualities.
- Sub-regions - areas with particular climates or topography.
If a GI is mentioned in the label 85% of the grapes must come from the stated GI.
South Australia zones and regions.
- Barossa - Barossa Valley, Eden Valley.
- Mount Lofty Ranges - Adelaide Hills, Claire Valley.
- Fleurieu - McLaren Vale.
- Limestone Coast - Coonawarra.
- Lower Murray - Riverland.
Two main areas of Barossa Valley.
- Plains (250 to 270mt), warm climate. Ripe full-body wines.
- Valley sides (they offer protection), cooler and fresher style.
How producers are making a fresher style of Barossa.
- Blend from plains and valleys.
- French oak instead of American.
- Harvest early.
What is the Barossa Old Vine Charter?
Association founded in 2009 to record, preserve and promote old vines.
Barossa has the world’s oldest vines. They were originally planted in 1840s but many were taking off because of a vine pull scheme in the 80s.
Main varietals planted in Barossa.
- Shiraz (66%).
- Cabernet Sauvignon.
- Grenache (Rhone-style blends).
- Chardonnay.
- Semillon (more full body than Hunter Valley).
Main soil of Barossa.
Ironstone. Good water retaining properties to ripen Shiraz.
Famous producers in Barossa Valley.
- John Duval.
- Glaetzer Wines.
Eden Valley main climatic and topographic influence.
600mt exposed hills - high rainfall (dry farming is possible, also good water retention soils) and winds can affect flowering and ripening.
Main varietals planted in Eden Valley.
- Riesling (more than 1/3).
- Shiraz (higher acidity, less body than Barossa)
Famous producers in Eden Valley.
- Henschke.
- Pewsey Vale.
Adelaide Hills general climate.
Cool to moderate maritime.
Main climatic influences in Adelaide hills.
Valleys and steep hillsides.
- Altitude - aspect, high-diurnal
- Proximity to the ocean - high rainfall (320mm during the growing season) disrupt fruit set and brings fungal.
Varietals planted in Adelaide Hills.
- Sauvignon Blanc (28%)
- Chardonnay (oaked, LMF).
- Pinot Noir (sparkling an dry).
- Shiraz (less planted).
Experimentation with Gruner, Blaufrankisch, Arneis, Fiano, Sangiovese, Nebbiolo.
Famous producers in Adelaide Hills.
- Shaw + Shaw.
- Penfolds.
Where are vineyards located in Clare Valley?
- On the hills and ridges.
- Valley floors running in between hills and ridges.
Main problem and how to solve it with Riesling in Clare Valley.
Sunburn.
Thick shading canopy.
Soil types and styles of Riesling in Clare Valley.
- Slate (Polish Hill) - low fertility, less aromatics, long bottle age.
- Limestone (Watervale) - fertile, aromatic, drink young.
McLaren Vale moderating influences.
- Proximity to the sea.
- Altitude.
McLaren Vale two main areas.
- North - altitude, poor low fertility soils. Premium producers.
- South - flatter, high fertility. Large vineyards (majority).
McLaren Vale is famous for what type of wine.
Red, inexpensive, high volumes.
Most planted varietals in McLaren Vale.
- Shiraz (45%)
- Cabernet Sauvignon.
- Grenache.
- Chardonnay.
Also Mediterranean varieties such as Mourvedre, Sangiovese, Fiano.

Blewitt Springs.
Sand over clay soils to help water retention. Premium prices.

Sustainable Winegrowing Australia.
Focus on sustainable water use.
Famous producers in McLaren Vale.
- Hardys (started with fortified wines in the 19th century).
- Mollydooker.

What contributes to the moderate maritime Bordeaux-like climate of Coonawarra?
- Flat land - sea breezes reach inland.
- Cloud cover.
