Suitability for cultivation and agronomic production

Roussanne has very long shoots and, as a consequence, requires carefull trellising. This variety can be pruned short or moderately long. This grape variety is well suited to poor clay-limestone soils that are rather stony and well exposed.
Susceptibility to diseases and pests

Roussanne is very sensitive to powdery mildew, grey rot, mites and thrips.
Technological potentiality

The bunches are small to moderate. The berries are small in size and turn red when fully ripe. Roussanne producespowerful wines of great finesse and complexity (floral and fruity notes of honey, hawthorn and apricot) with a good acidity balance. These wines are suited for ageing. This variety highlights and brings out the nuances of excellent terroirs.
