Note on grapevine variety datasheets
Regional vine planting data is available on the following site: visionet.
Only the principal ampelographic elements enabling the varieties to be characterised and identified are provided. They are presented according to the descriptor code recognised by the International Organisation of Vine and Wine (OIV), the International Union for the Protection of New Varieties of Plants (UPOV), the Community Plant Variety Office (OCVV) and Bioversity International (for more information, see the "Ampelographic glossary" menu).
The photographs of leaves and grapes were taken in natural conditions, on the vine, in very similar situations in terms of growing conditions (sandy soil, Mediterranean coast):
- Domaine de l'Espiguette (IFV), Le Grau du Roi (Gard),
- Domaine de Vassal (INRAE), Marseillan (Hérault),
- La Gaillarde Campus (Institut Agro | Montpellier SupAgro), Montpellier (Hérault).
Only a few photographs, including the tips of bunches, were taken in other conditions.
The growth stages indicated are the result of obsrvations made at the Domaine de Vassal Estate where the set of these varieties form a collection. The results are indicated compared to the Chasselas vine variety as a reference in order to make comparisons between years and different sites. As such, for information purposes, the dates for the Chasselas B growth stage at Domaine de Vassal are as follows:
- Bud burst, 21 March (average over 50 years)
- Grape maturity, 14 August (average over 50 years)
The size of grape clusters and berries indicated are based on the following scales:
|Wine grape varieties||Table grape varieties|
|Size||Bunch (g)||Berry (g)||Bunch (g)||Berry (g)|
|Very small||≤ 100||< 1||< 150||< 2|
|Small||100 - 200||1,5 - 2||150 - 250||2 - 3,5|
|Moderate||200 - 250||2 - 2,5||250 - 400||3,5 - 5,5|
|Large||250 - 400||2,5 - 3,5||400 - 700||5,5 - 8|
|Very large||> 400||> 3,5||> 700||> 8|
