Phenology
Bud burst: 4 days after Chasselas.
Grape maturity: mid-season, 3 weeks and a half to 4 weeks after Chasselas.
Suitability for cultivation and agronomic production
This variety is fertile, productive and has an erect bearing which allows it to be pruned short with limited training. Folle blanche is quite sensitive to spring frosts due to its early budburst.
Sensitivity to diseases and pests
This variety is very susceptible to grey rot (very compact bunches), black rot and to mites. It is also fairly sensitive to downy mildew and wood diseases.
Technological potential
The bunches and berries are medium in size. Folle blanche wines have a low degree of alcohol and are generally nervy and acidic. In southern areas this acidity drops when completely ripe. When not very affected by grey rot, the wines produced can be used to make excellent spirits. Folle blanche also has a good capacity for making base wine.
Clonal selection in France
The eleven certified Folle blanche clones carry the numbers 280, 281, 354, 558, 559, 560, 561, 562, 563, 1131 and 1132. A conservatory more than 180 clones was planted in 1993 in the wine-growing region of Nantes. An other conservatory of 70 or so clones was planted in the French department of Charente in 2010.
