The two main purposes of this study were to describe a specific sensory method, used by a trained sensory panel including chemical compounds reference development, to establish the most important descriptive and discriminative sensory attributes of different Port wine styles and brands and to compare the results of PCA with the results of CATPCA, in order to assess the feasibility of both techniques.pt
