Wine vinegars are highly valued mainly regarding the implemented acetification process Particularly in Argentina, most wine vinegars are made through industrial fermentation processes and few of them are produced in a traditional way but without added value Currently, the search for fast, accurate and low cost determinations makes UV Vis and NIR spectroscopies one of the most popular alternatives to determine the concentrations of chemical compounds as well as for authenticity studies The aim of this work was to develop an analytical methodology based on UV vis and NIR measurements in combination with multi block analysis to quantify a multi parametric analysis for the quality control of wine vinegars and, additionally, to differentiate them according to the implemented production method Different determinations that are normally used for the quality control of these products were carried out by applying standard methods
