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 and how is it caused?
1) Leaves turn red and the grape point breaks
2) 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
What are the five leading white platings?
1) Grenache Blanc
2) Viognier
3) Clairette
4) Roussanne
5) Marsanne
What is the red, white, rose percentage split in production terms across the Rhone?
1) 76% red
2) 14% rose
3) 10% white
When does Grenache ripen?
Late
What is a rising trend in Rhone viticulture?
Organics
Cotes du Rhone AOC and Cotes du Rhone Villages AOC account for approximately what percent of all Rhone wine production?
60%
What two viticultural hazards is Syrah vulnerable to?
1) Mites
2) Botrytis
What four disease pressures is Grenache vulnerable to?
1) Coulure
2) Downy
3) Phomopsis
4) Botrytis
When does Mourvedre bud and ripen?
Late
Is Mourvedre drought tolerant?
No
How is Mourvèdre best grown in the vineyard? (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
What are two positive attributes of Cinsault in the vineyard?
1) Drought tolerant
2) Heat tolerant
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
Why are Viognier and Roussanne yields often low and unpredictable?
Due to poor flowering and fruit set (coulure) exacerbated by the Mistral
When do Roussanne and Marsanne bud?
Late
Where do Roussanne, Marsanne and Clairette grow best?
On stone, low fertility soils (low fertility prevents vigour)
Marsanne and Roussane vulnerable to what three things?
1) Powdery
2) Mites
3) Botrytis
Why is Grenache Blanc’s early budding nature not considered an issue?
It is mostly planted in the southern Rhone where spring frost is less common
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 oxidises easily
What does Clairette contribute to a wine? (3)
1) Freshness and fruit - flower, fennel, apple, grapefruit
2) High alcohol
3) 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 (2)
1) Prone to oxidation and premature loss of colour if it is exposed to too much oxygen
2) Fermented and aged in concrete vats or stainless steel tanks.
What are two positive attributes of Bourboulenc in the vineyard? Why?
1) Late ripening
2) Loose bunches
3) Resistant to botrytis
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.
What vessel type can be said to be traditional in the Rhone of a) fermentation and b) maturation?
1) Concrete
2) Small/large wood
What are five production differences between cru and high volume red wines?
1) Hand vs machine
2) Cold soak vs flash detente/thermovinification
3) Warm vs mid-range fermentation temperatures
4) Intense, prolonged vs short maceration
5) Maturation vs quick release
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
By what method is most Rhone rose made? Example?
1) Short maceration (saignee), but with the intention of creating rose rather than concentrating a red wine
2) Tavel
What is another consequence of the Mistral wind?
It decreases vine vigour and leads to lower yields of higher concentration
Four common winemaking decisions for white wine?
1) Mid-range temperatures
2) MLC sometimes avoided
3) Lees stirring avoided in most cases
4) Oak for premium
What are the two red-only AOCs of the northern Rhone?
1) Cote-Rotie
2) Cornas
What are the three AOCs of the northern Rhone that can be red or white?
1) Saint-Hoseph
2) Crozes Hermitage
3) Hermitage
What are the three white only AOCs of the northern Rhone?
1) Condrieu
2) Chateau Grillet
3) Saint-Peray
What is the red, white and rose IGP of the northern Rhone?
Collines Rhodaniennes
