New Zealand Flashcards
New Zealand climate
Maritime
Except Central Otago - semi continental(protected by mountains)
South Island vs North Island temps
Cooler in S
Moderate in N
What protects the South Islamd vineyards from excessive rains and winds from Tasmania sea?
Southern Alps
Rainfall still high despite protection
Why are UV levels high in NZ?
Hole in ozone
Low levels of air pollution
Extended daylight hours from low latitude coupled with additional UV exposure allows for what
Tannin/color development
Increasing viable ripening period allowing for grape growing in cool sites
High diurnal range
High fertility soils, extra sunshine, additional UV demand what for quality fruit
Canopy management to inhibit excessive vegetation growth that could shade fruit
VSP with 2 canes
Up to 4 canes (Scott Henry) but high yields are hard to ripen in cool years
Planting densities in NZ are
Low but high yields due to conditions and training systems
Soils in NZ are
Free draining and necessitate irrigation despite high rainfall
Main predator and mitigation in NZ
Birds
Netting
Strong winds in NZ increase
Evapotranspiration

Sauv Blanc
PN
Chard

Merlot
Riesling

Gewurz
What encourages variety in winemaking styles in NZ?
No GI specific winemaking regulations
Producing the distinctive style of Marlborough SB in vineyard
High UV, adequate water, canopy mgmt for ripening
High diurnal- long grow season intense aromas high acid
Row orientation- tropical ripeness from exposed/grassy from shaded
Early picking for grassy
Machine harvest for skin contact to increase aromas
Producing distinctive Marlborough SB in winery
Protective winemaking to preserve primary fruit
Selected yeasts to promote aromatics
No MLC
Min lees aging for primary frruit
Ascorbic acid and CO2 during bottling for freshness
Greater Auckland
North Island
Historical center of production but now business/urban
Waiheke Island- warmer black grapes
