Name of the variety in France
This variety is originally from the Loire Valley and seemingly from Anjou.
In Bulagria, Chenin is officially designated as "Shanin". This synonym is officially recognized in France regarding plant propagation material.
In France, Chenin is officially listed in the "Catalogue of vine varieties" on the A list and classified. This variety is also listed in the catalogues of other Member States of the European Union: Belgium, Bulgaria, Cyprus, Czech Republic, Italy, Malta, Portugal and Spain.
Wine grape variety.
Evolution of cultivated areas in France
The identification is based on:
- the tip of the young shoot with a very high density of prostrate hairs,
- the young leaves with bronze spots,
- the adult leaves, with three or five lobes, a slightly open petiole sinus or with slightly overlapping lobes, medium teeth with convex sides, a strong anthocyanin coloration of veins, a blistered leaf blade, and on the lower side of the leaves, a medium density of prostrate hairs,
- the ellipsoid berries.
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.
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 fourteen certified Chenin clones carry the numbers 220, 278, 416, 417, 624, 880, 982, 1018, 1206, 1207, 1208, 1209, 1286 and 1348.
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.
