Suitability for cultivation and agronomic production
Clairette is a vigorous grape variety, which must be pruned short. Better yields are achieved on limestone, not fertile, lean and dry soils. Careful disbudding is needed. It has a semi-erect bearing and its shoots are a little susceptible to wind. At maturity, the peducunle of bunches lignifies.
Sensitivity to diseases and pests
This variety is susceptible to grape moths and mites. On the other hand, Clairette is relatively less sensitive to powdery mildew and grey rot.
Technological potential
The bunches and berries are medium in size. Clairette gives fairly alcoholic wines (and sometimes sweet with raisining or over-maturation), relatively low in acidity, with noticeable aromas (apple) and sometimes presenting a light harshness or bitterness on the finish. This variety can also be used to make sparkling wine.
Clonal selection in France
The ten certified Clairette clones carry the numbers 68, 69, 93, 94, 97, 98, 175, 207, 208 and 209. A conservatory of more than 130 clones was planted in spring 2007, in the wine-growing region of Bellegarde (French departement of Gard).
