Rhone Pt 3 -Northern Rhone General Flashcards
Where is the Northern Rhone sub-region located?
It begins 20 miles south of Lyon and stretches for 45 miles between Vienne and Valence.
How large is the planting in the N.Rhone?
Around 10,000 acres/ 4000 ha. It represents 4% of the total production area of the entire Rhone Valley.
What is the climate of the N.Rhone?
It is continental with some Mediterranean influences. It receives approximately 2350 hours of sunshine per annum.
What are the climate hazards of the N.Rhone?
Fog and frost in spring, hail in autumn and snow in winter.
Most years, autumn is good. What does this allow in N.Rhone?
In most years autumn is warm, dry and sunny. This allows for a rain-free harvest with no disease pressure.
Why is the window of ripening conditions smaller in the Northern as against the Southern Rhone?
Temperatures drop earlier in the North as fall advances. Early ripening varieties such as Syrah and Viognier are therefore favoured.
How was the Rhone Valley formed?
It is part of the rift system formed when the Alps rose. It was widened and deepened by the Rhone glacier. It created a steep gorge with some gradients of 60 deg.
Why did the Romans cultivate the Northern Rhone first?
Hillsides were prized. They excavated the slopes and terraced them to retain soil and mitigate erosion.
What are the main soils of the N.Rhone?
Granite subsoils with a fine topsoil of decomposed crystalline mica schist and granite sands. There are some pockets of limestone.
What additional soils do Crozes-Hermitage and Hermitage have?
CH - Pockets of GALETS, clay and loess/molasse.
H - Some clay and sand.
What are Galets? Molasse?
Galets - large, round stones;
Molasse - windblown sediment.
Which varieties are planted to stony soils? Clay and sandy soils?
Stony - Syrah;
Clay, sand - White varieties.
What benefit for the vine do stony soils have?
They trap heat during the day and radiate this back to the vine at night prolonging the photosynthesis and boosting ripening.
What are the main white grapes of the N.Rhone?
Viognier, Marsanne and Roussanne.
What are the main red grapes of the N.Rhone?
Syrah is the sole red grape of N.Rhone.
