AB High-quality wine vinegars with unique organoleptic characteristics are produced insouthern Spain under three Protected Designations of Origin (PDO), namely “Jerez”, “Condadode Huelva” and “Montilla-Moriles”. To guarantee their authenticity and avoid frauds, robust andlow-cost analytical methodologies are needed for the quality control and traceability of vinegars.In this study, we propose the use of ultraviolet-visible spectroscopy in combination with multivariatestatistical tools to discriminate Spanish wine vinegars according to their geographical origin, as wellas to predict their physicochemical and functional properties. Linear discriminant analysis provideda clear clustering of vinegar samples according to the PDO with excellent classification performance(98.6%). Furthermore, partial least squares regression analysis demonstrated that spectral datacan serve as accurate predictors of the total phenolic content and antioxidant activity of vinegars.Accordingly, UV-Vis spectroscopy stands out as a suitable analytical tool for simple and rapidauthentication and traceability of vinegars.
