Total phenolic compounds The average of total phenolic compounds in wine elaborated with the addition of enological enzymes was almost equal to the control wines (534.16 t 28.65 mg/L and 518.41 t 33.56 mg/L, respectively) (Figure 1A). These results did not agree with those reported by Gerbaux and others (2002) and Kelebek and others (2009) who described an increase of phenolic compounds in wine made with addition of enological enzymes versus the control wine. The final reason might be the quick action of the enological enzymes upon the internal part of the grape skins at the beginning of the fermentation process, which would result in a higher initial extraction of the phenolic compounds. However, Ducassea and others (2010) did not observe such difference.
