D3 - Australia 1: Overview + South Australia Flashcards
Provides an overview of Australia, plus examines the regions, grapes, methods of production, and styles of South Australia.
In what year did vines first arrive in Australia?
1788
Who was James Busby?
A native Scotsman who is considered to be the father of Australian wine. He brought over vines from Europe on his first trip to Australia in the early 1830s.
Vineyards in Australia are spread over a large area and have a wide range of different climates.
What are the latitudes of most vineyards in Australia?
30° – 37°S, the equivalent to southern Europe in the Northern Hemisphere.
What is the climate of Murray-Darling?
Hot continental.
Outside of Murray-Darling, most vineyards in Australia are situated closer in relation to what?
Cooling influences – Pacific and Indian Oceans, and altitude where available.
What is the name of the mountain range that runs from Queensland to western Victoria?
The Great Dividing Range.
Name a pro and a con regarding the cool ocean breezes that affect Australian vineyards.
- Pro: reduce risk of frost;
- Con: can disrupt fruit set.
The Great Dividing Range protects many of southeastern Australia’s vineyards from what?
Tropical weather systems that come from the Pacific and the northeast.
Why is Australia a favorable place to grow wine grapes generally?
It has intense sunshine, relatively low rainfall, and in most areas, low humidity (which means low disease pressure).
What are the two main environmental threats to Australia’s wine growing regions?
Drought and bush fires.
Select the correct answer.
Most of Australian viticulture is:
a. Hand-harvested only
b. Heavily mechanized
b. Heavily mechanized
What are the advantages of mechanized harvesting in Australia?
- Cuts down on labor costs;
- Covers big areas in short amount of time;
- Easily done at night;
- Grapes can arrive at winery quickly.
Cite 3 reasons why an Australian winemaker would hand harvest even though most vineyards are flat enough to machine harvest.
- Limit grape splitting and crushing;
- Maintain whole bunches;
- Greater selection at time of picking.
- What is the issue many soils have in Australia?
- How can this issue affect vines?
- High salinity – not enough rainfall to wash it away;
- Saline soils make it challenging for vines to get the nutrients it needs → reduced vine growth and possibly vine death.
- Which areas of Australia have remained free of phylloxera?
- In which areas is phylloxera present?
- Phylloxera-free: South Australia, Western Australia and Tasmania;
- Phylloxera present: Victoria, New South Wales
Name four areas/regions in Australia that have high humidity.
- Adelaide Hills;
- Southern Victoria;
- Hunter Valley;
- Parts of Tasmania.
What are the main vineyard pests in Australia?
- Birds;
- Kangaroos.
Select the correct answer.
Due to the climate of Australia, most grape varieties achieve optimum ripeness:
- In a narrow window of time
- In a wide window of time
What does that mean for harvesting timing?
- In a narrow window of time;
- Harvest must be done as quickly and efficiently as possible (machine harvesting helps with this a lot).
What are the five key red grape varieties in Australia?
- Shiraz;
- Cabernet Sauvignon;
- Merlot;
- Pinot Noir;
- Grenache.
What are the six key white grape varieties in Australia?
- Chardonnay;
- Sauvignon Blanc;
- Pinot Grigio;
- Semillon;
- Muscat Gordo Blanco (Muscat of Alexandria);
- Colombard.
- Higher alcohol, fuller-bodied Shiraz notably come from these two hotter regions in Australia.
- Medium alcohol, less full-bodied Shiraz comes from these two cooler regions in Australia.
- Hotter regions: Barossa Valley, McLaren Vale;
- Cooler regions: Yarra Valley, Grampians.
What winemaking techniques are Australian winemakers using to make less intense, more approachable styles of Shiraz?
- Reducing amount of extraction;
- Whole-bunch fermentation;
- Using less oak.
How does Cabernet Sauvignon taste different from Shiraz?
Cabernet Sauvignon will be higher in acidity and tannins than Shiraz, with ripe black fruit aromas of cherry and blackcurrant.
What winemaking techniques do Australian winemakers use to enhance the complexity, balance, and texture of their Chardonnays?
- Using ambient yeasts;
- Leaving a high level of solids in fermentation;
- Barrel fermentation and/or barrel maturation (typically French oak);
- Lees aging.
- Malolactic depends on the climate where the grapes were grown and the style of wine desired (hotter region may block malo whereas cooler regions may encourage it).
Pinot Grigio in Australia can be found in the neutral, Veneto-style and in the riper, Alsatian-style.
How can you tell which style the wine is just by looking at the label?
The label will read either ‘Pinot Grigio’ (Italian style) or ‘Pinot Gris’ (Alsatian style) to reflect the style of wine that’s in the bottle.
What is the hierarchy of Australia’s wine growing areas (GIs)?
From largest to smallest:
Zones: large areas which can cover a state or several states with similar climatic conditions (e.g. South Eastern Australia).
Regions: smaller than zones in size, but wines must demonstrate consistent and recognizable traits that differ from nearby regions (e.g. Margaret River, Clare Valley).
Subregions: smallest in size, these areas must be within one region and have distinct traits, such as climate, topography, or soil (e.g. Polish Hill River subregion within Clare Valley).
If an Australian wine is labeled with a GI and has a stated vintage or grape variety, what percent of the stated vintage and grape variety must be in the bottle?
85%
What regions does the South Eastern Australia Zone cover?
The entirety of Victoria, New South Wales and Tasmania along with the south-eastern corners of South Australia and Queensland.
