Sensitivity to diseases and pests
Prima N is not very sensitive to grey rot.
Technological potential
Prima N grape clusters are average, fairly loose with a long and not very lignified stalk. The berries are moderate to large in size and become intensely colored in a homogeneous manner before the grapes reach maturity. The skins are fairly thin and the pulp firm and juicy with a neutral flavor and moderate organoleptic quality. Prima N holds up well and has good capacity for long distance travel.
