Suitability for cultivation and agronomic production
Aubun has a semi-erect bearing. It is a fertile and rather rustic variety.
Sensitivity to diseases and pests
This variety is not very susceptible to grey rot and powdery mildew. On the other hand, it is quite sensitive to downy mildew and leafhoppers.
Technological potential
The bunches and berries are large. Under fertile conditions, this variety has difficulty to color its berries and alcoholic degrees are low. The red wines produced are usually ordinary and without finesse, but this Aubun can be used to produce pleasant rosé wines.

The two certified Aubun clones carry the numbers 168 and 350. A conservatory of 3 clones was planted in the French department of Vaucluse in 2001.
