Sensitivity to diseases and pests
Counoise N is not very sensitive to downy mildew, but is fairly susceptible to grey rot. 
Technological potential
The clusters are medium size and the berries are large. Counoise N produces fruity but not very colorful wines.
Clonal selection in France
The two approved Counoise N clones carry the numbers 508 and 725. A conservatory of a dozen clones was set up in 2001 in the Côtes du Rhône.
