The variations of redox potential ( E H ) reflect the oxidation–reduction reactions happening to the wine throughout its aging period. The present study shows the evolution of redox potential in a red wine during aging in different systems (barrels, oak chips and oak staves). All of them have undergone by the same aging conditions carried out in a wine cellar participating the Cigales Appellation of Origin Program (Spain). The monitoring of E H, basic parameters, color parameters and phenolic compounds explains their modifications, as well as the correlations between the E H and these parameters with aging time. The redox potential is a useful discriminant variable to differentiate wine aging systems.
