This variety is vigorous, fertile and productive and must be short-pruned and reserved, preferably in not very fertile and stony terroirs. Marsanne B produces long shoots which require careful and sufficient training. This variety is rather rustic, short cycle with late bud burst and is well adapted to cool climatic areas.
Sensitivity to diseases and pests
Marsanne B is sensitive to downy mildew, mites and grey rot.
Technological potential
Marsanne B clusters are large but the berries are small. Marsanne B produces dry or sparkling white wine, rather elegant, moderately or not very acidic with fine aromas. A badly managed production may adversely affect wine quality.
