33
Q

Describe the typical winemaking decisions for New Zealand Sauvignon Blanc.

A
  • Low temperature fermentation
  • Stainless steel / neutral vessel
  • Cultured yeasts increase favourable aromatics
  • MLF and lees ageing are avoided to preserve fruit
  • Chaptalisation is common in cooler years
  • Ascorbic acid and so2 ensure freshness after bottling
  • Minimise oxygen contact and keep fruit cold
34
Q

What conditions in the vineyard are needed for producing the distinctive style of New Zealand Sauvignon Blanc

A
  • High levels of light needed in the vineyard
  • Adequate water (irrigating where necessary)
  • Canopy management
  • High diurnal range: long season, intense aromas, high acidity
  • Mechanical hrvest creates som skin contact with juice leading to higher levels of herbaceous aromas
35
Q

Describe how row orientation and canopy management can create different flavours in New Zealand Sauvignon Blanc wines.

What else can produce different aromas in the wines?

A

Fruit on the sunny side of the canopy is fully ripe with tropical fruit flavours

On the shadier side higher levels of green pepper, grassy herbaceous aromas.

Slightly earlier picking can also promote herbaceousness in the wine, as can machine harvesting

36
Q

What techniques are New Zealand wine producers using to experiment with Sauvignon Blanc?

A
  • Barrel ferment
  • Lees stirring
  • Partial or full MLF
  • Oak maturation
  • Skin contact
  • Indigenous yeasts
37
Q

How might New Zealand winemakers make fresh, fruity, high volume red wines?

A
  • Mid range fermentation temperatures
  • Cultured yeasts
  • Neutral vessels
38
Q

Describe typical winemaking options for premium Pinot Noir and Syrah in New Zealand.

A
  • Whole bunch (varying proportions) adding herbal/ floral note
  • Cold maceration to extract colour and aroma (especially Pinot)
  • Extraction during the winemaking process depends on the grape variety and the desired style
  • Maturation in French oak: larger oak is more favoured for Pinot
39
Q

Describe the climate in Greater Auckland.

What is the main threat to the grape growing?

A

Moderate Maritime climate

40
Q

Name the three sub regions in Greater Auckland

A

Auckland
Gisborne
Hawke’s Bay
Wairarapa

45
Q

Is land under vine increasing or decreasing in Gisborne? Why?

A

Decreasing - more money can be made growing kiwis and apples

46
Q

Describe the main soils and topography typically found in Gisborne.

Where is higher quality fruit grown?

A

Flat, fertile flood plain of clay loam and silt.

Higher quality from hillsides where soils are poorer.

47
Q

Describe the climate in Gisborne.

A

Moderate maritime climate, with high sunshine hours and high rainfall (1,000mm)

48
Q

What climatic factor reduces the threat of frost in Gisborne?

A

Warming breezes from the north

49
Q

What factors can cause vines to be very vigorous in Gisborne?

A

High rainfall, long sunshine hours and fertile soils

50
Q

What is the rainfall like in Gisborne?

What effect can this have on grape growing?

A

High: 1,000mm

Increases vine vigour
Rain at harvest can cause dilution
High humidity: rot

51
Q

What is the main grape grown in Gisborne?

Describe the quality/ styles available

A

A

Hawke’s Bay

54
Q

Describe the climate and rainfall in Hawke’s Bay.

What region is it climatically similar to?

A

Moderate maritime climate with high rainfall (1,000mm)

Bordeaux

55
Q

Describe the main soils found in Hawke’s Bay

A

Gravelly alluvial soils similar to Medoc

56
Q

What is the main style of wine that Hawke’s Bay is known for?

Describe the price points available.

57
Q

What are the two best known subregions in Hawke’s Bay? Describe where these are and the climatic conditions.

A

Gimblett Gravels and Bridge Pa

Found further inland; warm days but less coastal influence means frost can be an issue

58
Q

Describe the soils found in Gimblett Gravels and Bridge Pa.

A

Both have alluvial terraces with gravelly top soils.

Gimblett Gravels’ stony topsoil retains heat and radiates it back to the vines at night. Soils are more free draining and irrigation is needed.

Bridge Pa has a deeper topsoil of sandy clay and loam. Soils have better water retention.

59
Q

What grapes are planted closer to the coast in Hawke’s Bay?

What styles of wine do they produce?

A

Syrah - fresh style, matured in French oak with some new. Blackberry and black pepper. Outstanding, premium

60
Q

Which is the most southerly wine region in North Island New Zealand?

A

Wairarapa

61
Q

Wairarapa focuses on ____ wines from ____ yielding vines.

_____ and ____ are the most grown varieties

A

Premium wines from low yielding vines.

62
Q

Name the three subzones in Wairarapa

A

Masterton

63
Q

Describe the climate in Wairarapa

A

Cool maritime climate.

Summers are warm but diurnal range is high slowing ripening and prolonging the growing season

64
Q

Why is tourism big in Wairarapa?

A

It is close to the large city of Wellington. It is known as Wellington Wine Country

65
Q

Why are yields particularly low in Wairarapa?

A

Strong winds come directly of the Cook Strait.

This can affect flowering and fruit set, negatively impacting yield

Frost can also lessen yield, but installation of wind machines has reduced the threat

66
Q

What effects do strong winds in Wairarapa have on grape growing?

A
  • Reducing yields

- Berries have thicker skins: Pinot Noir here has higher levels of fine grained tannins

67
Q

What soils are found in Wairarapa?

How do these affect grape growing?

A

Range, but the most dominant is free draining alluvial gravel terraces with silt loam and loess

Silt loam and loess take a long time to warm up and have a cooling effect which slows ripening, resulting in more concentrated complex fruit flavours

68
Q

What price and quality of Pinot Noir is found in Wairarapa?

What clones are commonly planted?

A

V.good to outstanding, premium priced.

ABEL CLONE
A cutting from DDRC: flowers late, missing the worst weather, productive with large berries (inhibited by winds)

69
Q

What price and quality of Sauvignon Blanc is found in Wairarapa?

Compare the style with an example from Marlborough
