Critical acclaim
Describe the climate in Marlborough, including rainfall and sunshine hours.
Cool climate with moderately warm summers and mild winters.
Sunshine hours are long, rainfall is around 650mm
What factor influences rainfall in Marlborough?
Is irrigation common and why?
Surrounding mountain ranges mean the region is protected from much rainy weather (650mm)
Irrigation is common as soils are mostly free draining and alluvial. Aquifers are used.
What climatic influences mean that Sauvignon Blanc from Marlborough is intense in aroma and flavour?
- High levels of sunshine

Why is machine harvesting commonplace in Marlborough?
Flat terrain
Short contact between skin and juice promotes precursors of green pepper and passion fruit aromas
Where is Wairau?
Describe the climatic conditions here
Runs from west Marlborough along the Wairau River to the mount of Cloudy Bay in the east.
Conditions vary along the valley, but the west/ inland area has less moderating influence from the ocean, higher diurnal range, warmer days, cooler nights and higher frost risk
Describe the soils found in Wairau Valley
Former riverbed; combination of gravel, silt, sand loam and clay in varying amounts.
Soils are more fertile and the water table is higher nearer the coast: higher yields than inland
Free draining soils require more irrigation but also provide warmth needed to extend the growing season.
Which four grapes are commonly planted in Wairau?
Mostly Sauvignon Blanc
Also Pinot Noir, Chardonnay and Pinot Gris
Describe the soils in Southern Valleys, Marlborough.
How does this affect which vines are grown here?
Soils have more clay here than the rest of Marlborough; cooling influence means grapes are picked later than elsewhere.

Where is Moutere Hills?
North west of the town of Nelson, in Nelson
Name the two smaller areas within Nelson

TOPGRAPHY:
Undulating, but low altitude (up to 150m)
SOILS:

How does Sauvignon Blanc from Nelson compare with that of Marlborough?
Nelson is more restrained than Marlborough
Some producers may add complexity with lees ageing or oak
Describe how Pinot Noir from Waimea Plains and Moutere Hills in Nelson might differ.
WAIMEA:
Lighter bodier, little or no oak, good to v. good.

Include any warming or cooling influences

Warming influence from the dry, north easterly winds
What effects do winds have on North Canterbury? (5)
- Warming influence

- Increases potential hang time
What is the rainfall in North Canterbury?
What is the main factor affecting this?
Low - 650mm
The Southern Alps act as a rain shadow, protecting the region from the worst of the rains
What factors make irrigation necessary in North Canterbury?
