Suitability for cultivation and agronomic production
Molette is vigorous with a fairly erect bearing. Its fertility is average when pruned short, but production becomes substantial when this variety is pruned long. Molette seems well adapted to clay-limestone and sandy soils.
Susceptibility to diseases and pests
This variety is susceptible to grey rot and downy mildew.
Technological potentiality
The bunches are medium in size and the berries are small. Molette produces clear, and acidic, but relatively common and not very aromatic wines, with a fairly high alcohol degree.
Clonal selection in France
The two certified Molette clones carry the numbers 1039 and 1230. A conservatory of twenty or so clones was planted in 1999 in the wine-growing region of Savoie.
