Suitability for cultivation and agronomic production

Sensitivity to diseases and pests
Servanin N is susceptible to downy mildew but is not very affected by grey rot.
Technological potential
Grape clusters and berries are small. Servanin N produces tannic wines with good color, but acid and low alcohol level.
