The identification is based on:
- the yellow young leaves with bronze spost and a high to very high density of prostate hairs,
- the shoots with red internodes,
- the small adult leaves, entire or with shallow lateral sinuses, a slightly open or closed, V- or lyre-shaped petiole sinus, short teeth compared to their width at the base with convex sides, a strong anthocyanin coloration of veins, an involute, blistered leaf blade, undulate between the veins, and on the lower side of the leaves, a high density of erect and prostate hairs,
- the slightly ellipsoid berries.

Phenology
Bud burst: 3 days before Chasselas.
Grape maturity: mid-season, 2 weeks and a half after Chasselas.
Suitability for cultivation and agronomic production
This variety has moderate vigor and good fertility.
Susceptibility to diseases and pests
Despite having very compact grape clusters, Orbois does not seem too susceptible to grey rot.
Technological potentiality
The bunches are medium to large in size and the berries are small. The sugar accumulation potential is relatively high for a fairly low acidity. It is especially used as a base wine to blend it with other grape varieties.
Clonal selection in France
The three certified Orbois clones carry the numbers 205, 206 and 504. A conservatory of twenty or so clones was planted 2007 in the French department of Loir-et-Cher.
