Use
Wine grape variety
Phenology
Time of budburst: 1 day before Chasselas.
Time of maturity: mid-season, 3 weeks to 3 weeks and a half after Chasselas.
Technological potential
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.
Cultural and agronomic skills
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.
Elements of description
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.
