Suitability for cultivation and agronomic production

This productive and fertile variety has an erect bearing. The young vines are oftentimes vigorous but can weaken quickly with overproduction. For this reason, yields must be managed by pruning short. This variety has a relatively short growing cycle (this is interesting for limit zones), steady production and is easy to grow.
Susceptibility to diseases and pests

Jurançon noir is susceptible to grey rot but is rarely affected by wood diseases.
Technological potentiality

The bunches and berries are medium in size. Jurançon noir produces slightly or moderately alcoholic wines that are not very intensely colored. The wines are light, simple which must be quickly consumed. Jurançon noir is also used to make lively and fruity rosé wines.
Clonal selection in France

The two certified Jurançon noir clones carry the numbers 438 and 571. A conservatory of 60 or so clones was planted in the French department of Lot in 2012.
