EnglishThere is very little information on effects of Penicillium on aroma of passito wine. This study analyzed chemical composition and sensory properties of Amarone wines produced from withered grapes artificially contaminated by P. expansum or P. crustosum. Changes in properties of the two wines were evident by comparing wines obtained from healthy and Botrytis cinerea infected grapes used as controls. Penicillium infection affected primary and volatile composition of Amarone wine. Sensory profiles of these wines, obtained by descriptive analysis, resulted in clear differences in the wines between themselves and the control wines. Partial least square regression analysis explained only partially the relationship between molecules and sensory descriptors, and showed the existence of complex interactions of compounds mainly involved in specific aroma attributes. GColfactive analysis showed a greater number of odour regions in P. crustosum wine compared to control wines. Useful insight was provided into understanding how Penicillium rotten grapes affect Amarone wine properties
