In general, a decrease in esters and alcohols and an increase in carbonyl compounds occurred during aging, as reported in several papers (Malfliet et al., 2008 and Vanderhaegen et al., 2003). Our results confirmed data reported in the literature. It is clear that storage temperature played a role in the decrease in volatile components but to a lesser extent than storage time. In fact, for the two temperatures, the decrease was more evident at t2 (Fig. 2b). The decreased concentration of esters during aging could depend on the presence of yeast-derived extracellular esterases that catalyze ester breakdown
