This productive and fertile variety grows upright. The young vines are oftentimes vigorous but can weaken quickly with overproduction. For this reason, care needs to be taken to manage yields with short pruning. This vine variety has a relatively short growing cycle (this is interesting for limit zones), steady production and is easy to grow.
Sensitivity to diseases and pests
Jurançon noir N is susceptible to grey rot but is not frequently affected by wood diseases.
Technological potential
Grape clusters and berries are moderate size. Jurançon noir N produces slight or moderately alcoholic wines with not very intense color. the wines are light, simple and quickly consumed. Jurançon noir N is also used to make lively and fruity rosé wines.
Clonal selection in France
The 2 approved Jurançon noir N clones carry the numbers 438 and 571.
