Summary:The possibility of predicting sluggish fermentations under oenological conditions was investigated by studying 117 musts of different French grape varieties using an automatic device for fermentation monitoring. The objective was to detect sluggish or stuck fermentation at the halway point of fermentation. Seventy nine percent of fermentations were correctly predicted by combining data analysis and neural networks. En étudiant les courbes de cinétique fermentaire de 117 moûts de différentes variétés françaises de vigne, on recherche la possibilité de prédire les fermentations languissantes. Une combinaison de méthodes d'analyse de données et de réseaux de neurones conduit à 79% de prédictions correctes au vu de la courbe jusqu'à mi-réaction.
