Australia Flashcards
Australian Wine History
- 1788 vines brought by settlers
- 1850’s first exports - phylloxera in Europe gave opportunity
- Domestic demand grew from tourists returning from Europe
- 1950’s rise of the big companies (Orlando/Jacob’s Creek, Lindeman, Hardys, Penfolds)
- Late 1980’s - shift to export market, marketing body Wines of Australia embraced modern advertising
- Style shift to big, oak (vanilla),
- Peak in late 2000’s at 170k ha, financial crisis, South American competitors, droughts pushing up irrigation costs
- premiumisation has kept Australian wines in the game
Climate
Inland (Murray-Darling Basin), hot continental
Coastal areas are maritime
Coonawara maritime even though not close to coast
Great Dividing Range provides altitude (Orange, Grampians, Macedon)
Rain shadow from mountains: Riverland only gets 150mm rain, but on the other side Hunter Valley gets 500 and is hot and humid
Soil
Varied
Coonawarra has distinctive red soil (terra rossa)
McLaren Vale - over 40 unique soil types
Vineyard Management: Lack of Water
Murray-Darling Basin for irrigation, not always enough
Adelaide Hills and Margaret River have higher winter rainfall and store in dams
McLaren Vale and Coonawarra have underground water sources, also pioneering recycled water
Drip irrigation most often used to conserve water
Vineyard Management: Vigorous Vines
Old vines combat high vigour
divided canopy systems like Scott-Henry or Smart-Dyson
Vineyard Management: Labour
Fairly expensive, so mechanised where possible.
Not many steep slopes
Vineyard Management: Soil Salinity
Not enough rainfall to carry away salt deposits and water from underground aquifers find their way up.
Can make it hard to vines to get nutrients - Chardonnay particularly vulnerable.
Rootstock selection (based on v. berlandieri)
Vineyard Management: Wildfires
Diluting tainted grapes
Vineyard Management: Sustainability
Many areas dry so very good for organic viticulture
Vineyard Management: Pests
Birds and Kangaroos
Grape Varieties
Black Grapes: (54%) Shiraz Cabernet Sauvignon Merlot Pinot Noir Grenache
Chardonnay Sauvignon Blanc Pinot Grigio Semillon Riesling Muscat Gordo Blanco
Grape Varieties: Shiraz
25% total harvested fruit
hotter areas (Barossa and McLaren Vale): full-bodied, high alcohol, high soft tannin, dark fruit, earhty & spicy
cooler areas (Yarra, Grampians): less full bodied, higher acidity, some red fruit, black pepper
Very good and Outstanding: made in open fermenters with punch downs/pumpover for soft extraction
GSM Blends, co-fermented with Viognier, blended with CS
Grape Varieties: Cabernet Sauvignon
Higher in acidity and tannin than Shiraz, ripe black fruit, (blackcurrant and cherry), with oak.
Coonawarra: eucalyptus
Margaret River: blended with Merlot, herbal notes, slightly riper
Grape Varieties: Merlot
Mostly in blends.
As single-varietal: medium bodied with medium tannin and red fruit to fuller bodied with riper, black fruit character
Better clones have been planted recently, leading to better quality
Grape Varieties: Pinot Noir
In cool and moderate areas like Yarra Valley, Mornington Peninsula, and Tasmania.
Medium-bodied with medium alcohol, medium to high acidity, red fruit.
Whole bunch fermentation, cold maceration for colour and flavour, and stem inclusion for tannic structure.
Grape Varieties: Grenache
Only 1%, used in GSM blends
Old vines for single varietal in McLaren Vale, Eden Valley, Barossa Valley
Traditionally low acidity, high alcohol, and jammy. Now picked earlier, higher acidity, lower alcohol, fresher red fruit.
Sometimes whole bunch or stem inclusion for aromas & colour.
Small new oak overwhelms flavours, so older/bigger oak vessels used.
Grape Varieties: Chardonnay
Big range of styles/prices
Inexpensive: Tank fermented, oak chips/staves if any, sometimes blended with Semillon (Chard brings ripe fruit flavours)
Higher end: medium to medium (+) acidity, well-integrated oak, ambient yeast, high level of solids during ferment, oak fermentation, malo (in cooler areas where there is enough acidity), lees ageing, barrel maturation.
Grape Varieties: Sauvignon Blanc
Cooler climates - mid priced wines
Hotter climate - large volume, inexpensive wine
Less herbaceous than Marlborough.
Adelaide Hills: premium, with intense fruit character from citrus to tropical. Sometimes oaked/lees. Sometimes blended with Semillon.
Grape Varieties: Pinot Grigio
picked early for neutral style like Veneto, or riper for for style like Alsace (riper, fruitier, spicier).
Labelled Pinot Grigio for neutral style, Pinot Gris for fuller-bodied style
Grape Varieties: Semillon
Blended with SB, Chard, or as single varietal
Low alcohol, high acidity from Hunter Valley. Neutral when young, but develops complexity.
Barossa Valley has fuller body, higher alcohol, oak (not as age-worthy as Hunter Valley). Recently picking earlier for lighter style.
Riverina of New South Wales: noble rot for sweet wines
Grape Varieties: Riesling
Clare Valley, Eden Valley, Great Southern, Canberra, Tasmania.
Some sweet, but usually dry with high acidity. Apple, lemon, grapefruit, peach.
Premium using free range only. Some wine makers experimenting with skin contact.
Grape Varieties: Muscat Gordo Blanco and Colombard
Muscat of Alexandria = Muscat Gordo Blanco, for sparkling Moscato
Riverland
Cheap blended wines
Zones
Largest area, no rules, not terroir-led,
Can be entire state or multiple states (South Eastern Australia)
Most states divided into smaller zones
South Australia smaller zones: Barossa, Mount Lofty Ranges, Fleurieu (which are also the Adelaide “super zone”
Regions
Smaller than zones

Sub-regions
Recognise areas with particular climates, topography, soil.
14 sub-regions registered

Introduced 1990
85% GI, Vintage, or Grape if it is stated on the label

Victoria, New South Wales, Tasmania, plus south-eastern corners of South Australia and Queensland
Inexpensive, high volume wine
Mostly Murray-Darling Basin
Riverland, Murray-Darling, Riverina

North of Adelaide
Barossa Valley on valley floor, Eden Valley in hills to the east
Shiraz
South Australia, Barossa Zone: Barossa Valley
protected by Eden Valley hills to the east, low hills to the west, Adelaide hills (Mount Lofty Ranges) to the south
one of Australia’s largest regions: 11,000 ha
160mm rainfall, irrigation necessary
full, ripe reds
Old vine Shiraz and Grenache, Cab Sauv, Chardonnay, Semillon
Semillon: higher alcohol, fuller body than Hunter Valley
South Australia, Barossa Zone: Eden Valley
Rolling exposed hills, part of Mount Lofty Ranges
up to 600m above sea level, sometimes too steep for mechanisation
230mm rainfall, good water-holding soil
Old vine Shiraz and Riesling, Grenache,
Eden Valley Riesling: dry, high acidity, medium alcohol
Eden Valley Shiraz: higher acidity, lower alcohol, structure tannins
Mount Lofty Ranges Zone
range of mountains east of Adelaide, surrounding Barossa on 3 sides
Most important areas are Adelaide Hills and Clare Valley
Mount Lofty Ranges, Adelaide Hills
Valleys and steep hills restrict mechanisation
Cool to moderate maritime climate
280-320mm rainfall in winter and spring (can interrupt fruit set), caught in dams and used for irrigation - also water from underground sources
Higher humidity
SB, Chard, Pinot in the higher altitude vineyards, full-bodied reds (Shiraz) in the lower, west-facing slopes
Latitude gives intense sunlight, so flavours are riper
Sub regions: Picadilly Valley and Lenswood
