One of the strongest factors that affects the volatile profile of sparkling wine is the winemaking process. Here we focus on determining the effects of the second fermentation and aging on lees of sparkling wine from Pais grape variety combining different anal. techniques for the first time in sparkling wine: gas chromatog./mass spectrometry/olfactometry and sensorial anal. During the second fermentation and aging, there was a significant loss of esters that might be related to the adsorption on lees and ester volatility and chem. hydrolysis. The concentration of several compounds such as some esters (di-Et succinate, Et lactate, and Et isovalerate) increased during aging and could be used as aging markers. Vitispiranes were identified as the best norisoprenoids aging markers for young sparkling wines (12 mo of aging). Also, PCA showed that time of aging on lees affected mostly esters and terpenes. On the other hand, the diminution of fruity/floral impact odorants during aging was not perceived in sensorial trials. Our results suggest that the responsibility for fruity/floral nuances in sparkling wine might reside in a few high-impact aromatic compounds, such as Et isobutyrate, isoamyl acetate, Et hexanoate, β-phenylethanol and di-Et succinate.
