Recebido em 2/4/09; aceito em 9/11/09; publicado na web em 23/3/10 VOLTAMETRIC ELECTRONIC TONGUE APPLICATION TO WINES CLASSIFICATION AND CORRELATION STUDY WITH THE CHEMICAL AND SENSORY CHARACTERIZATION. This paper presents the analytical application of a novel electronic tongue based on voltammetric sensors array. This device was used in the classification of wines aged in barrels of different origins and toasting levels. Furthermore, a study of correlation between the response of the electronic tongue and the sensory and chemical characterization of samples was carried out. The results were evaluated by applying both principal component analysis and cluster analysis. The samples were clearly classified. Their distribution showed a high correspondence degree with the characteristics of the analyzed wines, it also showed similarity with the classification obtained from organoleptic analysis.
