Phenology
Bud burst: 1 day before Chasselas.
Grape maturity: mid-season, 3 weeks to 3 weeks and a half after Chasselas.
Suitability for cultivation and agronomic production
Chenin is a vigorous and fertile variety whose production potential depends a lot on agronomic soil fertility where it is grown. It is susceptible to heat. Budburst is early. After a spring frost, the secondary buds demonstrate very low fertility.
Susceptibility to diseases and pests
Chenin is particularly susceptible to grey rot, powdery mildew and wood diseases. It resists better to downy mildew, black rot and to anthracnose.
Technological potentiality
The bunches are medium to large and the berries are small to medium in size. Depending on the growing conditions and the terroirs (limestone, schists) this variety can be used to produce sparkling wines, white wines, or liqueur wines. Acidity potential is high and the wines produced are elegant, generally quite lively, with aromas of honey.
Clonal selection in France
The thirteen certified Chenin clones carry the numbers 220, 278, 416, 417, 624, 880, 982, 1018, 1206, 1207, 1208, 1209 and 1286. More than 300 clones are planted in a conservatory in the wine-growing region of Anjou since 1996. An other conservatory-collection of fiften or so clones was planted in the French department of Aveyron in 1995.
