Phenology
Bud burst: 9 days after Chasselas.
Grape maturity: mid-season, 2 weeks to 2 weeks and a half after Chasselas.
Suitability for cultivation and agronomic production
This variety, with its late budburst, shows good vigor and is sufficiently fertile when pruned short. However, its susceptibility to coulure or to millerandage may sometimes causes irregular production. Bunches peduncles are short. Négrette produces good results on boulbenes, gravelly and even sandy soils.
Susceptibility to diseases and pests
Négrette is very susceptible to grey rot, powdery mildew, vine leafhoppers and mites.
Technological potentiality
The bunches are small and the berries small to medium in size. This variety produces pleasant and fragrant wines that are rich in anthocyanin. As they are generally not very tannic and acidic, these wines lack liveliness and brillance. Their ageing capacity is limited so this wine should preferably be consumed quickly. Négrette also produces balanced rosé wines.
Clonal selection in France
The five certified Négrette clones carry the numbers 456, 580, 581, 582 and 663. A conservatory of 190 clones was planted in 1997 in the wine-growing region of Fronton (French department of Haute-Garonne). An other conservatory of fifty or so clones was planted in the French department of Vendée in 2012.
