White wine grape · Vitis vinifera
A white wine grape of the northern Rhône, described in the French cultivar reference as rustic and well adapted to cool areas and recorded by UC Davis as Marsanne.
Plantgrape describes Marsanne as originally from the Northern Côtes du Rhône region and records no officially recognized synonym in France or the European Union. UC Davis FPS independently lists France as its country of origin and gives Avilleran, Ermitage, Grosse Roussette, Hermitage and Marsanne Blanche among its synonyms.
Plantgrape describes Marsanne as vigorous, fertile and productive, requiring short pruning and preferably not very fertile, stony terroirs, and notes it produces long shoots that require careful and sufficient training. These are attributed descriptions, not pruning or site prescriptions.
Plantgrape describes Marsanne as rather rustic with a short cycle and a late budburst, well adapted to cool climatic areas, sensitive to powdery mildew, mites and grey rot, and warns that badly managed production may adversely affect wine quality. These are reference observations, not treatment advice.
