1. Name three regions where Semillon is planted in Australia and describe each style.
Hunter Valley:
High acidity, low alcohol, light body.
Neutral when young, develops honey and toast with age.
Barossa Valley:
Fuller-bodied than Hunter Valley.
Margaret River:
More herbaceous and aromatic.
2. Name a weather hazard in Barossa, Hunter Valley, and Margaret River and explain how it is managed.
- These regions have maritime influence.
- Rain at harvest can cause rot.
- Good canopy management helps reduce this risk.
3. Explain how natural factors affect the style of Syrah in warm or hot regions.
Warm and hot regions produce high sugar levels, leading to higher alcohol and fuller body.
Wines are often very ripe or jammy, with dark fruit (blackberry) and spice (liquorice).
They have low acidity and soft, ripe tannins.
4. State three methods a winemaker can use to balance high alcohol and jammy styles.
- Pick grapes earlier to reduce sugar and alcohol and keep fresher fruit.
- Use gentle cap management to control extraction of tannin and flavor.
- Blend with other varieties such as Mataro (Mourvèdre) to add fresher fruit character.
- Use some whole bunch fermentation to increase freshness.
5. What is the climate of Murray Darling?
- Warm Mediterranean climate
6. Name two regions where old Grenache is planted in Australia.
- Barossa Valley
- McLaren Vale
