One of the components presents in oak wood is gallic acid, which brandies extract during their aging process. In this study, a HPLC technique for the separation and identification of gallic acid by direct injection, has been performed. Studies, which tested the accuracy of the method, showed a 99.59% recovery percentage for this acid. This technique has been applied to the analysis of commercial brandies, thus revealing the existing differences in the gallic acid concentration according to the aging system followed: Static or traditional and dynamic or criaderas and soleras.
