showed comparable values and a significant linear correlation,
(correlation coefficient r=0.98, pb0.05), indicating a high agreement
between them. The data reported in Table 1 indicate that both thewine
coupage and aging period significantly influenced the antioxidant
activity of lees surface. In particular, cells fromcoupage Awines showed
higher antioxidant activities than those from coupage B. This could be
explained by the different compositional characteristics of lees surface,
which depends on the medium in which they are grown (Ribéreau-
Gayon et al., 2006). Chemical composition of each wine coupage was
determined to find a possible influence on lees samples antioxidant
capacity. Nevertheless, base wine general parameters (Table 2) do not
seem to explain the differences observed between lees samples grown
in distinct wines, showing the need for further researches focused on
this topic.
