What other climatic factors is Jura vulnerable to besides growing season rainfall? (2)
1) Spring frost
2) Hail
Describe Jura’s altitude and aspect
1) West-facing slopes of the Jura Mountains
2) Altitudes between 250 and 400m
Why are many of Jura’s vineyards grassed between rows? (2)
1) To reduce erosion due to the slope
2) To limit herbicide use (grass grown between rows means that herbicide use can be limited to the ground immediately below the vines)
How are Jura’s vines typically trained and trellised and why?
1) VSP, replacement cane pruned
2) To encourage the flow of air and reduce risk of fungal disease

A thick-skinned variety with good resistance to fungal diseases.

Early
Poulsard is is vulnerable to what diseases? (2)
1) Coulure
2) Fungal diseases
When does Poulsard ripen?
Early
What is Trousseau prone to? (2)
1) Poor flowering
2) Excess vigour
Where and on what soil is Trousseau best planted? Why?
1) Either the warm lower part of the slope or on well-exposed higher, steeper slopes
2) On the warm gravels
