What does the D3 Wines of the World unit cover?
D3 applies growing-environment, grape-growing, winemaking and wine-business knowledge to the principal wine regions. Explain how these factors influence wine style, quality and price, and compare regional approaches with appropriate qualifications.
Growing conditions
Connect climate, weather, altitude, aspect, soils and water supply with ripeness, grape composition and vineyard risk.
Grapes and vineyard choices
Explain why varieties and vineyard systems suit particular sites, including the effects on yield, quality and cost.
Winemaking and maturation
Relate fruit condition, extraction, fermentation, blending and maturation to contrasting regional wine styles.
European wine regions
Study the principal regions of France, Germany, Austria, Hungary, Greece, Italy, Spain and Portugal.
Wine regions beyond Europe
Compare the USA, Canada, Chile, Argentina, South Africa, Australia, New Zealand and China.
Wine business and regional identity
Explain how origin rules, production costs, reputation and routes to market influence the wines offered and the prices they can achieve.
