The accumulation of flavor precursor-3MH in Chardonnay grape increased around early morning and decreased during the day. The daily fluctuation of flavor precursor-3MH accumulation in grape was common to several grape cultivars irrespective of the sampling year. These results suggested that early morning harvest might yield higher concentrations of 3MH and 3-mercaptohexyl acetate in wines than daytime harvest. These findings could contribute to improving viticultural and enological practices with the aim of producing aromatic wines. ER -
