(139 cards)
1
Q
What separates the Hunter Valley climatically from all other major wine producing regions?
A
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.
2
Q
Why is Coonawarra considered maritime despite being 100km inland?
A
Australia is a relatively flat country and often there is little to stop the cooling influence
of the oceans spreading some distance inland
3
Q
Most of Australia’s vineyards lie between what latitude?
A
30°-37° (the equivalent of North Africa and
Southern Europe in the Northern Hemisphere)
4
Q
Tasmania lies are what latitude?
A
41° and 42°S (corresponding
to Porto and central Italy).
5
Q
What are three viticultural concerns in Australia?
A
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
6
Q
What two divided canopy systems have been used and why?
A
1) Scott-Henry
2) Smart-Dyson
3) To manage vigour and ensure vine balance
7
Q
Mechanisation is common in most Australian regions. Why might a winegrower harvest by hand? (3)
A
1) To limit grape splitting and crushing
2) To permit greater selection of fruit during harvesting
3) To maintain whole bunches
8
Q
Describe the issue of soil salinity and how it impacts the vine
A
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
9
Q
What are two options to combat soil salinity?
A
1) Selecting suitable rootstocks
2) Changing irrigation patterns to supply larger volumes of water at less frequent
intervals
10
Q

Q
What benefit is there from a labelling perspective to Australia’s regional hierarchy?
A
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.
19
Q
Under the LIP, if a GI, vintage or grape variety is mentioned on the label, what per cent of the grapes must conform?
A
85%
20
Q
Why was the South Eastern Australia Zone created?
A
To allow
blending from grapes grown across the zone and the majority of wines labelled as such are inexpensive, high-volume wines.
21
Q
Why is Riverina slightly cooler than Murray Darling and Riverland?

47
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.

50
What is the location and climate of the Fleurieu Peninsula?
1) Located south of Adelaide, with Gulf St Vincent to the north and the Southern Ocean to the south.

cool breezes tempering the warm Mediterranean climate.
51
What are the soils of Blewitt Springs?

Describe Coonawarra's Terra Rossa soil
Free-draining iron-rich loam over a hard limestone base
58
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.

and lead to lower yields of concentrated
grapes

123
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
124
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
125
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
