Up and down
1990: 59,000ha
late 2000s (peak): 170,000ha
now: 146,000ha
Why has Australian vineyard shrunk in last 20 years?
Various reasons:
- Oversupply;
- Competition fro other non-Euro countries repliacting the model;
- worsened by strength of Aussie Dollar (2008 crash) making Aussie wine more expensive than eg Argentina and Chile;
- drought > expensive water > go out of business
What is the impact of drought on Aussie viticulture?
Serious droughts push up cost of water
Many growers forced out of business
Aussie land under vine shrinking has had what effect on the type of wine produced?
Less focus on inexpensive, high volume
More focus on small production, high price
=> maintain strong position on export markets
Most Aussie vineyards at what latitude?
30-37S (equivalent to North Africa, Southern Europe)
NB Tasmania is 41-42S
Climate in Murray-Darling Basin
hot continental
Effect of Indian or Southern Ocean on Aussie vineyards?
Cooling influence, moderating daily and seasonal temperatures
Australia is quite flat. So what?
Nothing to stop cooling influence of oceans going further inland,
eg Coonawarra: 100km inland yet continental climate

(Heat and sufficient water leads to vigour)
How can growers manage vigour and ensure vine balance in eg. warm Australian region (new vines)?
Divided canopy systems eg Scott-Henry, Smart-Dyson
Comment on soil salinity in Oz?
An issue!
Over time, soils become more saline (not enough rainfall to carry away salt deposited in irrigation water)
Saline soil makes it difficult for vine to get water it needs => reduced vine growth/DEATH
Managed through rootstocks and changing irrigation (larger amounts less frequently)
How to combat soil salinity in Oz?
Select suitable rootstocks
Change irrigation patterns (larger volumes, less frequently)
Phylloxera generally not present in Oz, but newer vneayrds often planted on rootstocks. Why?
Prevent future threa to fphylloxera
Combat acidity and salinity in soil
