Suitability for cultivation and agronomic production
Sylvaner is a variety with a steady production. It is however rather sensitive to spring frosts and its wood sometimes has difficulty to lignify. Sylvaner is not suited to terroirs that induce too much chlorosis.
Sensitivity to diseases and pests
Sylvaner is very sensitive to powdery mildew, downy mildew and grey rot.
Technological potential
The bunches are small and the berries are small to medium in size. Sylvaner produces fairly acidic and relatively neutral wines.
Clonal selection in France
The two certified Sylvaner clones carry the numbers 50 and 487. A conservatory of approximately 300 clones was planted in Alsace in 1990.
