Suitability for cultivation and agronomic production
Colombard B is a fertile, very vigorous and productive vine variety. It can be long or short-pruned depending on production objectives. Pruning is fairly difficult because Colombard B wood is hard. At maturity, a tendency to shatter can sometimes be noted.
Sensitivity to diseases and pests
This variety is slightly susceptible to powdery mildew on the leaves and grey rot at grape maturity.
Technological potential
The grape clusters and berries are medium size. This variety enables producing pleasant, aromatic wines with a good acidity. Eaux-de-vie obtained from Colombard B are of avergae quality and are especially used for blending.
Clonal selection in France
The 14 approved Colombard B clones carry the numbers 551, 552, 553, 605, 606, 607, 608, 609, 625, 626, 695, 938, 1179 and 1180. Over 180 clones are grouped together in two conservatories planted in 1995 and in 2002 in the Gers
