Ch. 31 – Australia Flashcards
Wine history of Australia
Phylloxera in Europe prompted exports from Australia
- after phylloxera, focus returned to domestic market
- fortified wines
1950s
- major companies founded
- e.g. Penfolds
- started to modernize the industry (steel and temperature control)
Wine Australia (1980s)
- focus on export markets
- modern, varietal labelling with style descriptors
- world’s fifth largest exporter
Since 1990s:
- plantings fallen
- due to oversupply and higher competition
- shift towards quality
Climate in Australia
Very favourable environment for viti
- intense sunshine due to low latitude
- low rainfall, low humidity
- grapes ripen reliably
Wide range of climates
- hot continental Murray-Darling Basin
- most regions rely on cooling influences
Relatively flat
- cooling influence of ocean can travel long distance inland (e.g. Coonawarra)
- producers increasingly looking to higher altitude areas
Great Dividing Ridge
- protects southern regions from tropical weather coming from Pacific
- creates rain shadow in some regions
Challenges:
- Spring frost can be issue in colder areas
- Winds from ocean reduce frost but can disrupt flowering
- Drought is a constant problem
Soil in Australia
Very complex geology
- all known rock types can be found
Some regions are known for distinct soils
- Terra rossa in Coonawarra
Vineyard management in Australia
Irrigation
- even in wet regions, due to free-draining soils
- Murray-Darling Basin rivers (but even these have run low in dry years)
- Rainwater collected in dams
- Underground water sources
- recycled wastewater
- as sustainable as possible, e.g. drip irrigation
High vigor
- due to heat + irrigation
- old vines naturally reduce vigor
- Scott-Henry, Smart-Dyson can be used for newer vines
Heavily mechanized
- aided by wide spacing and flat or gently sloping vineyards
- relatively high labour costs
- remote locations
- some harvesting by hand for premium wines
- reduce damage, greater sorting, and whole bunches
Soil salinity
- not enough rain to carry away salt deposited from irrigation
- more difficult for vine to get water
- reduced vigor
- Chardonnay very sensitive
- managed by rootstock and changing irrigation patterns to larger volumes of water at less frequency
Bush fires and smoke taint
Phylloxera
- many regions did not have problem
- quarantine and biosecurity laws
- rootstocks still used to deal with soil salinity and acidity
- present in Victoria and NSW
Low humidity
- ideal for sustainable/organic
- exceptions such as Hunter Valley
Pests = kangaroos and birds
Evolution of Australian wine styles
Originally full-bodied, ripe, fruity wines with plenty of oak
Now, more diversity
- site selection
- vineyard management
- precise harvest dates
Experimentation
- ambient yeast
- skin contact
- lees contact
- solids in ferment
- whole bunch and stem inclusion
Screwcap is most common closure
Shiraz in Australia
25% of all plantings
Warmer regions:
- full bodied, high in alcohol, high level of soft tannins
- pronounced aroma of dark fruits and earthy, spicy tones
- Develops leather
Cooler regions
- less fruit intensity and distinct black pepper aroma
Trend toward less intense, more approachable style
- reducing extraction
- whole bunch
- reducing new oak
- American oak is traditional, French increasing used
Widely used in blends
- GSM, Shiraz-Viognier, Bordeaux varieties
Cabernet Sauvignon in Australia
Single varietal or blends (Bordeaux or Shiraz)
Cooler or warmer climate
- higher acidity and tannin than Shiraz
- ripe black fruit (blackcurrant and cherry)
- oak
Leading regions:
- Coonawara, with distinctive mint and eucalyptus aromas
- Margaret River, where it’s slightly riper in style and often blended with Merlot
Merlot in Australia
Widely used in blends but also single-varietal
Wìde range of styles
Better clones introduced in recent years
- raising quality
Pinot Noir in Australia
Cool or moderate climates
- Yarra Valley
- Mornington Peninsula
- Tasmania
- med body, med alcohol, high acidity, red fruit (cherry, raspberry)
Whole bunch, cold maceration, stem inclusion
Often matured in French oak
- new oak is declining
Grenache in Australia
GSM blends with Shiraz and Mataro
Old bush vines (McLaren Vale, Barossa)
- modern style has greater freshness, higher acidity, lower alcohol and fresher fruit
- sometimes proportion of whole bunches or stems
- Small new oak barrels tend to overwhelm it
- large barrels or old oak
Chardonnay in Australia
Almost in every region
Ripe fruit (citrus, peach), med (med+) acidity and well-integrated oak
- ambient yeast
- high levels of solids
- barrel ferment
- lees ageing
- barrel maturation (French oak)
- malo depends on climate
Sometimes blended with Semillon
Sauvignon Blanc in Australia
Cooler climate regions
- Adelaide Hills
- citrus, tropical notes
- less herbaceous than Marlborough
Warmer regions for inexpensive wines grown at high yields
Usually fermented in steel
- sometimes lees contact or barrel fermented
Sometimes blended with Semillon
Semillon in Australia
Single varietal or blended with SB or Chardonnay
Hunter Valley
- Low alcohol, high acidity, unoaked style
- fairly neutral in youth
- develops with bottle age
Barossa
- fuller bodied, higher alcohol and oak notes
Sweet botrytised wines in Riverina
Pinot Gris/Pinot Grigio in Australia
Italian style:
- picked early
Alsace style:
- riper, fruitier, spicier, fuller bodied
Mornington Peninsula, Tasmania
Riesling in Australia
Cooler regions
- Clare and Eden Valleys
- Tasmania
Bone dry, high acidity (apple, lemon, lime, grapefruit)
Fermented in steel
- experimentation with skin contact and lees aging
System of GIs in Australia
Zones
- no rules regarding boundaries and no requirements for shared geographic or climatic characteristics
- can cover entire state
Regions
- must have consistent and distinct qualities
- must produce at least 500 tonnes of grapes a year across at least 5 differently owned vineyards
- Tasmania is a region (not a zone)
Sub-regions
- particular topography, climates, soils
Gives range of labelling options
Labelling law in Australia
governed by:
- Label Integrity Programme (LIP)
If GI, vintage or grape is stated
- 85% of grapes must conform
No GI-based rules for growing or winemaking
South Eastern Australia Zone
Covers whole Victoria, NSW and Tasmania + corners of South Australia and Queensland
Allows blending across the zone
- high volume wines
Mostly from Murray-Darling Basin
- Riverland
- Riverina
- Murray-Darling
Hot continental climate
- rivers provide slight cooling influence
- rain shadow of Great Dividing Range
- sandy free-draining soil
- rivers provide irrigation water, but can run low in dry years
HQ for some of Australia’s biggest producers:
- e.g. De Bortoli
Shiraz, Chardonnay, Semillon
- ripe, med body, high alcohol, low acidity
