Suitability for cultivation and agronomic production
Clairette B is a vigorous vine variety, which must be short-pruned. Better yields with limestone, not fertile, lean and dry soils. Careful disbudding is needed. It grows semi-erect and its shoots are a little susceptible to wind. At maturity, the grape clusters stems lignify.
Sensitivity to diseases and pests
This variety is susceptible to grape caterpillars and mites. On the other hand, Clairette B is relatively less susceptible to powdery mildew and grey rot.
Technological potential
The grape clusters and berries are medium size. Clairette B enables making fairly alcoholic wine (and sometimes sweet with raisining or overmaturation), relatively low acidity with noticeable aromas (apple) and sometimes marked with a light harshness or bitterness on the finish. This variety can also be used to make sparkling wine.
Clonal selection in France
The 10 approved Clairette B clones carry the numbers 68, 69, 93, 94, 97, 98, 175, 207, 208 and 209. A conservatory with over 130 clones was planted in spring 2007, in a vineyard in Bellegarde (Gard).
