Suitability for cultivation and agronomic production
Danlas displays strong vigor and a horizontal bearing. As it is sensitive to the wind, it must be trained and pruned long. It is not very susceptible to millerandage and coulure.
Susceptibility to diseases and pests
Danlas is very susceptible to phomopsis, downy and powdery mildew. On the other hand, it is not very sensitive to grey rot.
Technological potentiality
Danlas's bunches are large, moderately compact with a long and pigmented peduncle. The clusters are homogeneous, easy to pick and to package. The berries are medium to large in size. The skin is thick and the pulp relatively juicy, soft with a neutral flavor. Danlas has a good storage and transport capacity. When vinified, Danlas produces ordinary and not very aromatic wines.

The only certified Danlas clone carries the number 499.
