Phenology
Bud burst: 11 day after Chasselas.
Grape maturity: mid-season, 2 weeks and a half after Chasselas.
Suitability for cultivation and agronomic production
This vigorous variety must be carefully trained and planted on well exposed plots in order to limit the risks of brotrytis bunch rot.
Susceptibility to diseases and pests
Muscadelle is susceptible to powdery mildew, wasps, grape moths and very sensitive to grey rot.
Technological potentiality
The bunches and berries are medium in size. Once maturity has been reached, Muscadelle can produce moderately alcoholic, not very acidic and slightly aromatic wines. These wines can sometimes be sensitive to oxidation.
Clonal selection in France
The three certified Muscadelle clones carry the numbers 610, 1216 and 1217. A conservatory of almost 90 clones was planted in the Bergeracois region (French department of Dordogne) in 1996. An other conservatory of almost 50 clones was planted in the French department of Lot-et-Garonne in 2006.
