7. The Rhone Valley Flashcards
What is the climate of the northern Rhone?
Continental
What is the climate of the southern Rhone?
Mediterranean
How much land is under vine in the northern and southern Rhone respectively?
1) 4,200 ha
2) 65,000
What is Syrah decline/disorder?
An issue related to injury at the graft union between a scion and a rootstock that result in pits, grooves, cracks, and necrosis. Such an injury could be produced by pathogens including viruses.
What are the five key black grape varieties of the Rhone?
1) Grenache
2) Syrah
3) Mourvedre
4) Cinsault
5) Carignan
When does Grenache ripen?
Late
What four disease pressures is Grenache vulnerable to?
1) Coulure
2) Downy
3) Phomopsis
4) Botrytis
When does Mourvedre bud and ripen?
Late
Describe the suitable growing environment for Mourvedre (3)
1) Deep calcareous soils with small but steady water supplies
2) Best pruned short
3) Suited to cordon training or bush vines
What three disease pressures is Mourvedre prone to?
1) Mites
2) Leafhoppers
3) Sour rot
What is sour rot?
A disease that affects ripening bunches due to insect or bird damage to grapes, which then become prone to bacteria and fungi
Why must care be taken in the winery to ensure Mourvedre has adequate access to oxygen?
It is prone to reduction
How is Mourvedre typically aged?
In old oak
When does Cinsault bud?
Late
Cinsault is vulnerable to what five things?
1) Chlorosis
2) Esca
3) Eutypa
4) Mites
5) Grape moths
Why is Cinsault highly suitable for early drinking reds and roses?
The lifted aromas of the variety are most prominent in the first year after the wine is made
When does Viognier bud?
Early
What are Viognier yields often low and unpredictable?
Due to poor flowering and fruit set (coulure)
When does Marsanne bud?
Late
Where does Marsanne grow best?
On stone, low fertility soils (low fertility prevents vigour)
Marsanne is vulnerable to what three things?
1) Powdery
2) Mites
3) Botrytis
When does Roussanne bud?
Late
Roussanne is vulnerable to what five things?
1) Wind
2) Coulure
3) Powdery
4) Botrytis
5) Mites
What does Grenache Blanc contribute to a blend?
Low intensity ripe green fruit and some floral notes, high alcohol and low acidity
What is Clairette prone to?
Autumn rains as it is late ripening
How much Clairette be treated in the winery?
Gently as it oxidised easily
What does Clairette contribute to a wine?
Freshness and fruit, with white flower, fennel, apple and grapefruit notes, has high alcohol and low to medium (–) acidity.
When does Bourboulenc ripen?
Late
What does Bourboulenc contribute to a wine?
Lemon flavour, medium (+) acidity
and medium alcohol
Explain the winemaking style required for Grenache and why
Grenache Noir is prone to oxidation
and premature loss of colour if it is exposed to too much oxygen and therefore is typically fermented and aged in concrete vats or stainless steel tanks.
Explain the winemaking style required for Syrah and why
Syrah is prone to reduction and therefore has to be pumped over more often and is often aged in oak to provide gentle oxidation, adding to cost.
Why is the incidence of fungal disease lowered in the northern Rhone?
The cool Mistral wind from the north
How long is the northern Rhone from north to south?
65km
What is another consequence of the Mistral wind?
It decreases vine vigour and leads to lower yields of higher concentration
What are the eight AOCs of the northern Rhone?
1) Cote-Rotie
2) Condrieu
3) Chateau Grillet
4) Saint-Joseph
5) Crozes-Hermitage
6) Hermitage
7) Cornas
8) Saint-Peray
What is the red, white and rose IGP of the northern Rhone?
Collines Rhodaniennes
In which directions do most Cote-Rotie vineyards face?
East and south-east
How are vines in Cote-Rotie trained?
Single- or double-Guyot and tied to one or two poles
What are echalas?
The poles to which Cote-Rotie’s vines are tied
Describe the terroir of Cote-Rotie
Steep, often terraced slopes facing east and south-east with high sunlight, shelter from the wind, and poor stony soils.
What per cent of Viognier is permitted in Cote-Rotie?
20%
What is the preferred rootstock in Cote-Rotie?
3309
What is the typical planting density in Cote-Rotie?
10,000 vines per ha
What is the maximum yield in Cote-Rotie?
40 hL/ha
If Viognier is used in Cote-Rotie, how must it be fermented?
Co-fermented with Syrah
What are two common maturation vessel sizes in Cote-Rotie?
1) 225l barrique
2) 500-600l demi-muids
