WINES OF THE WORLD 🇦🇺 Australia Flashcards
Where the vineyards in Australia are located
Much of Australia is covered by desert and tropical rainforests, while vineyards are mainly in the SE (Southern Australia, Victoria, New South Wales and Tasmania) with some on the opposite side (Western Australia). Relatively flat, with some mountain ranges (the Great Dividing Range). Wide variety of soil types.
Climate of Australia
Inland, the vast Murray-Darling Basing is hot and continental. Most regions benefit from cooling influences (some are close to the Indian or Southern Oceans coast, while others inland have no barriers from the coast). Protection from tropical weather systems by the Great Dividing Range. Many areas have low humidity (exceptions for Adelaide Hills, southern Victoria, Hunter Valley and parts of Tasmania - 2011 was unusually wet).
Hazards in Australia
Spring frost in cooler areas. Drought with the risk of lack of water (historically from the rivers of the Murray-Darling Basin, but now they started to run low, others bring water from winter rainfall - Adelaide Hills or Margaret River - storing them in dams, others use underground water sources - McLaren Vale and Coonawarra - or use recycled wastewater - suburbs of Adelaide). Soil salinity (not enough rainfall or saline water from deeper aquifers to the surface). Bush fires due to hot and dry summers. Birds and kangaroos.
Main grape varieties of Australia
Old vines of Shiraz and Grenache in South Australia. Mainly black varieties (54%). Shiraz, Chardonnay, Cabernet Sauvignon, Merlot, Sauvignon Blanc, Pinot Gris, Muscat Gordo Blanco, Semillon, Colombard, Pinot Noir, Riesling.
Harvest for wines from Australia
Mechanical harvest allows one to cover a large area in a short time, which can happen during the night. Hand harvest is usually for premium wines (whole bunch, greater selection, limited grape splitting and crushing). A very narrow window of time, so possibility to pick certain varieties early for logistical.
Key winemaking operations for Shiraz wines in Australia
Trend to reduce the intensity by reducing the amount of extraction, using the whole bunch and/or reducing new oak. Open fermentation tanks with manual or mechanised punch downs to obtain very good or outstanding quality.
Key winemaking operations for Grenache wines in Australia
Traditionally, new oak while now whole bunch or stem inclusion and old/large barrels.
Key winemaking operations for Chardonnay wines in Australia
Tank fermentation, oak flavours (chips or staves) for inexpensive wines. Ambient yeast, high solids in fermentation, barrel fermentation, lees ageing for the higher quality wines. Malo according to style and climate.
Key winemaking operations for Sauvignon Blanc wines in Australia
Stainless steel, also lees contact or barrel fermentation for fuller bodied wines.
Key winemaking operations for Riesling wines in Australia
Stainless steel and bottling soon, premium wines from free-run juice only. Experimenting with pre-fermentation skin contact and lees ageing.
Blending possibilities for Shiraz in Australia
Also used in blends GSM (Mataro) or with Viognier (co-fermentation for premium wines), and with Cabernet Sauvignon (softness and body).
Blending possibilities for Chardonnay in Australia
Blended with Semillon in inexpensive wines.
Blending possibilities for Colombard in Australia
Blended in inexpensive wines, neutral style, often with Chardonnay.
Blending possibilities for Muscat Gordo Blanco in Australia
Cheap blending.
Key maturation practices for wines in Australia
French oak for reds, new oak is reducing.
Finishing operations for wines in Australia
Large use of screwcaps, even on premium wines.
Classification system for wines in Australia
- Zone
- Region
- Sub-region
Zone (classification system in Australia)
The largest areas, no rules regarding the drawing of boundaries and no requirements for shared geographic or climatic characteristics. One zone can cover an entire state while South Eastern Australia covers several. Most states have been divided into a number of further zones (South Australia includes Barossa, Mount Lofty Ranges and Fleurieu). Usually for multiregional blends. 28 zones.
Region (classification system in Australia)
Smaller than zones, 65 regions, vary in size but must have consistent and distinct qualities, must usually produce 500+ tonnes of grapes a year across at least five differently owned vineyards each of at least 5 ha (Tasmania is considered as a region).
Sub-region (classification system in Australia)
Only in some regions (Hunter Valley and Great Southern), 14 sub-regions, they have particular climate, topography or soils.
Label Integrity Programme
LIP is the authority that governs Australian wine labelling. If vintage of single grape, 85+% of the grapes must conform. If multiple varieties, they must be listed in descending order. LIP ensures that labels truthfully reflect what is in the bottle. Detailed records by growers, producers, and suppliers under the control of Wine Australia which oversees the LIP. No GI-based rules on grape growing and winemaking.
Types of businesses that operate in Australia
Important companies started in the 1950s, such as Orlando (Jacob’s Creek), Lindemans, Hardys and Penfolds. Decrease in wineries in the last 10 years, many became grape growers. Mainly small producers. Production volumes (also 87% of export) are dominated by five main companies: Accolade Wines, Casella Family Brands, Treasury Wine Estates, Pernod Ricard and Australian Vintage.
The largest Australian companies
Accolade Wines, Casella Family Brands, Treasury Wine Estates, Pernod Ricard and Australian Vintage.
Wine Australia
The government authority that funds and coordinates research and development valuable to the wine industry. It controls also the export and promotes Australian wines through marketing and educational courses. New approach to marketing wine, labels with taste descriptors, from the 1980s.
