Australia Flashcards
Provide some of the key points in Australia’s history (phylloxera, export, vineyard area)
- Great parts phylloxera free due to strict quarantine regulations -> some of the oldest plantings worldwide
- 1850s: phylloxera outbreak in Europe gave Australia a golden opportunity
- 1980s: shift to export market -> marketing and making wine more accessible
- Vineyard area increased singificantly until late 2000s and then fell again to 146,000 ha
- Many shifted more towards quality production
Between what latitudes do vineyards spread?
- Mostly 30-37°S (comparable to Southern Europe)
- Some 41-42°S (Tasmania)
On a high level, what are the main climatic influences?
- Low latitude -> intense sunlight
- Cooling influences from the ocean -> relatively flat, so maritime influence can reach far inland
- Some mountain ranges that provide cooler sites through altitude
- Mountain ranges create barrier from topical weather and provide rain shadow
- Drought is a constant threat
What is the production level and how does it compare to other countries?
- 12.6 mn hL
- 7th largest, not far behind Chile and Argentina
What is one of the main threats and how is it countered?
- Lack of water
- Most vineyards rely on irrigation
- Water historically mostly from rivers, but they start to dry out
- Regions with higher rainfall build reserves, other rely on underground water sources
- -> Efficient irrigation systems and sustainable water usage are critical
What effect does the intense sunlight have on wine growing?
- Vines grow vigorously
- Plantings of old vines naturally combat high vigor
- Newer plantings use Scott-Henry or Smart-Dyson to manage vigor and ensure even ripening
In general, how is the degree of mechanization?
- Heavily mechanized because of
- wide vine spacing
- flat or gently sloping land
- high labor costs
- remote locations of vineyards
- Nevertheless, some harvest by hand, esp. for most expensive wines
What is a general issue with the soil and how is it managed?
- Salinity (not enough rainfall to carry away the salt deposits)
- Managed through
- -> suitable rootstocks
- -> changing irrigation patterns (e.g., larger volumes at less frequent intervals)
What is a major threat because of the heat?
- Bush fires
- Smoke taint
How much of the vineyard area is farmed sustainably and why?
- 25%
- Low humidity -> low risk of fungal diseases
What are two general natural hazards and what can be done against it?
- Birds: Netting
- Kangaroos: No solution
What is the balance between black and white varieties and what are the top 5 varieties grown (incl. %)?
- Black: 54%, White: 46% -> roughly equal
- Shiraz (24%)
- Chardonnay (21%)
- Cabernet Sauvignon (15%)
- Merlot (7%)
- Sauvignon Blanc (5%)
How are wine bottles typically sealed?
Screwcaps (even at premium prices)
Describe the typical style of Shiraz from hotter and cooler regions and name examples (intensity, aromas, body, tannin, alcohol)
- Hotter regions, e.g., Barossa Valley, McLaren Vale
- Pronounced intensity
- Dark fruit, earthy and spicy notes
- Full body
- High levels of soft tannins
- High alcohol
- Cooler regions, e.g., Yarra Valley, Grampians
- Less intensely fruity
- Red and black cherry and black pepper
- Less full-bodied
- Medium alcohol
What is the general trend regarding the style of Shiraz? And how is it achieved?
- Trend is towards less intense, more approachable styles
- Less extraction
- Whole bunch fermentation
- Lower levels of new oak
- Very good and outstanding quality Shiraz is often made in open fermentation tanks with manual or mechanised punch downs for soft extraction of tannins
