31. Australia Flashcards
What separates the Hunter Valley climatically from all other major wine producing regions?
It is the only major wine-producing region to the east of the Great Dividing Range, receiving more rainfall (500mm) and has a
distinctive hot and humid climate.
Why is Coonawarra considered maritime despite being 100km inland?
Australia is a relatively flat country and often there is little to stop the cooling influence
of the oceans spreading some distance inland
Most of Australia’s vineyards lie between what latitude?
30°-37° (the equivalent of North Africa and
Southern Europe in the Northern Hemisphere)
Tasmania lies are what latitude?
41° and 42°S (corresponding
to Porto and central Italy).
What are three viticultural concerns in Australia?
1) Spring frosts - careful selection of a site that drains its cold air is required to mitigate this risk.
2) Winds blowing in off the ocean can sometimes disrupt fruit set (while reducing frost risk)
3) Drought/fire
What two divided canopy systems have been used and why?
1) Scott-Henry
2) Smart-Dyson
3) To manage vigour and ensure vine balance
Mechanisation is common in most Australian regions. Why might a winegrower harvest by hand? (3)
1) To limit grape splitting and crushing
2) To permit greater selection of fruit during harvesting
3) To maintain whole bunches
Describe the issue of soil salinity and how it impacts the vine
Saline soils can make it more difficult for
the vine to get the water it needs and leads to reduced vine growth and possibly death
What are two options to combat soil salinity?
1) Selecting suitable rootstocks
2) Changing irrigation patterns to supply larger volumes of water at less frequent
intervals
What variety is particularly susceptible to soil salinity?
Chardonnay
Many of Australia’s vineyard areas have low humidity: notable exceptions include what four regions?
1) Adelaide Hills
2) Southern Victoria
3) Hunter Valley

How many registered regions are there in Australia?
63
How many registered sub-regions are there?
14
What benefit is there from a labelling perspective to Australia’s regional hierarchy?
It gives producers a range of labelling options.
For example, wine made using grapes grown in the Eden Valley Region could be labelled as Eden Valley, Barossa, Adelaide, South Australia or South Eastern Australia.
Under the LIP, if a GI, vintage or grape variety is mentioned on the label, what per cent of the grapes must conform?
85%
Why was the South Eastern Australia Zone created?
To allow
blending from grapes grown across the zone and the majority of wines labelled as such are inexpensive, high-volume wines.
Why is Riverina slightly cooler than Murray Darling and Riverland?
It benefits from a slight maritime influence as there are no mountains between it and the coast
What are the three ‘engine room’ regions of South East Australia?
1) Riverina
2) Riverland
3) Murray Darling

Why might Barossa producers blend Shiraz from both Barossa regions?
To combine the intensity and body of wines from the warmer Barossa Valley with the elegance and higher acidity of wines from the cooler Eden Valley
What gives the Barossa Valley its climate?
Its sheltered location
The Barossa Valley is a plain protected
on the west by low hills, on the east by the Eden Valley Region and on the south by the Adelaide Hills
What is the Barossa Valley’s climate?

What is the climate of Adelaide Hills?
Cool to moderate maritime with temperatures varying due to altitude (400-500m) and proximity to the ocean.
What are two important sub-regions of Adelaide Hills?
Piccadilly Valley and Lenswood
Adelaide Hills has a high diurnal range due to altitude, but the wines often show riper fruit than expected. Why?
The relatively low latitude means the sunlight is still intense
What are two viticultural hazards in Adelaide Hills?
1) Rain in spring that might disrupt fruit set
2) Rot due to high humidity
What are the three common varieties on Adelaide Hills?
1) Sauvignon Blanc
2) Chardonnay

What is the climate of Clare Valley?
Warm but the hot summer temperatures are tempered by cool afternoon breezes and cold nights creating a wide diurnal range
What do growers of Clare Valley Riesling need to be conscious of and how is this managed?
1) Sunburn due to intense sunlight and low latitude
2) Canopies are allowed to grow thickly
to provide shading on the western side to protect the vines from the full glare of the afternoon sun.
How and why does Watervale Riesling differ from Polish Hill?
1) More aromatic, floral style which can be drunk when younger
2) More fertile limestone soils compared with the slate of PH
Name two significant Clare Valley producers

4) Cloud cover during the growing season
Describe Coonawarra’s Terra Rossa soil
Free-draining iron-rich loam over a hard limestone base
What is Terra Rossa considered so highly? (3)
1) The roots may struggle
to penetrate, restricting the vine’s access to water.
2) The soil is also slightly alkaline which
restricts the uptake of a number of vine nutrients.
3) Both of these factors control vigour
and lead to lower yields of concentrated
grapes
Name the four regions of the Port Phillip Zone

2) Mornington Peninsula
3) Geelong
4) Macedon Ranges
What is Yarra Valley’s climate?
Cool to moderate climate with considerable variation due to altitude

2) Upper Yarra - cooler, higher altitude sites in the south-east.
What are the two soil types in the Yarra Valley (upper vs lower)?
1) Lower Yarra - loamy clay soil is low in fertility and well drained, meaning irrigation is still often necessary
2) Upper Yarra - deeper and more fertile volcanic soils which can be dry-farmed
What is the main viticultural hazard in the Yarra Valley?
Fungal disease due to high rainfall
Two key producers of Yarra Valley?
Mount Mary and Yarra Yering
Besides Pinot Noir and Chardonnay, what two other varieties are commonly found in the Yarra Valley?
1) Shiraz
2) Cabernet Sauvignon
Why are frost and rot very uncommon in the Mornington despite the cool spring temperatures?
Due to the wind off Port Phillip Bay and the Bass Strait
What are the main two soil types of Mornington?

Margaret River is surrounded on three sides by which two oceans?
1) The Indian Ocean to the north and west
2) The Southern Ocean to the south
What two effects does the Indian Ocean have on Margaret River and what is the benefit?
1) The Indian Ocean is relatively warm meaning that temperatures do not drop away much at night
2) Moderates temperatures at low latitude
3) Allows grapes to ripen longer each day than they can in regions with cooler nights
Why does Margaret River relatively have relatively few weather hazards? (2)
1) The maritime influence also means spring frosts are rarely a problem.
2) Annual rainfall is relatively high for Australia (1,000mm+), but most of this rain is in the winter
Describe Margaret River’s soils
Gravelly and free-draining, meaning irrigation is essential but low in fertility, moderating vigour
