Many of the volatile compounds synthesized by yeast also change in response to the nitrogen concentration. It
has been suggested that nitrogen management of wine fermentation can be an effective tool to modulate wine
aroma composition and style. The aim of this study was to investigate the influence of clarification time on the
must of the white grapes, and to establish a practical understanding of the effect of the nitrogen content
(amino acids and ammonium) on the must in relation to volatile profile of the wine. The musts were clarified
by applying two settling time: 12 h and 30 h, and submitted to the same microvinification procedure. The results
showed that the must clarification time, influenced significantly the nitrogen compounds content, where the
total amino acid content was higher in musts clarified for a shorter time. Moreover, the aromatic profile of
these experimental wines was clearly influenced by the must clarification time. Principal components analysis
showed a strong influence of the must clarification time on the separation of the wines. The results confirm
that the management of the nitrogen content of the musts can be used as a tool to obtain wines with different
aromas. |
