Phenology
Bud burst: 6 days after Chasselas.Grape maturity: period II, 3 and 1/2 weeks after Chasselas
Suitability for cultivation and agronomic production
This variety has a somewhat irregular fertility and must be long pruned. Frequently a substantial part of the buds don't burst. The clusters keep well on the vine trunk and have peduncles which lignify.
Sensitivity to diseases and pests
Generally good resistance to grey rot. This variety is likewise not very sensitive to downy mildew, but is it is sensitive to leafhoppers.
Technological potential
Clusters are medium size and compact while the berries are small to medium size. Fer N produces lively wines, moderately colored but rather tannic and rustic with typical (wild) aromas. When the grapes have reched maturity, provided that the yields are managed, Fer N can produce fruity aromas (black currant, red fruits).
Clonal selection in France
The nine approved Fer N clones carry the numbers 420, 421, 556, 557, 628, 670, 671, 672 and 895. Two conservatories including a total of 120 clones have been set up in vineyards in Gaillac (Tarn) and in the Aveyron.
