Suitability for cultivation and agronomic production
Pineau d’Aunis N displays moderate vigor, is very susceptible to browning and is fertile when short-pruned. Its production sometimes tends to be alternately irregular and is sometimes susceptible to chlorosis.
Sensitivity to diseases and pests
Due to the compact nature of the grape clusters, this grape variety is susceptible to grey rot. It is however not very susceptible to phomopsis.
Technological potential
Grape clusters are moderate in size and the berries are small. Pineau d’Aunis N produces light and not very colored wine for making rosé wines or base wine used for sparkling wines. The quality for this vine variety drops quickly when yields increase.
Clonal selection in France
The 2 approved Pineau d’Aunis N clones carry the numbers 235 and 289. A conservatory with this vine variety including 350 clones was set up in Vendomois (Loir et Cher) in 1997.
