In this study, a series of six casks for each of seven different producers have been investigated by an expert Panel of eight judges, aiming at (i) assessing the degree of variability of the different sensorial attributes with samples ageing, and (ii) evaluating the similarity/dissimilarity among the various parameters together with the degree of agreement of the panellists.
Given the three-way nature of the data (samples × panellists × sensory attributes) the PARAFAC method has been used, and a satisfactory model was obtained, highlighting the efficacy of three-way analysis in dealing with the different sources of data variability, extracting the relevant information and displaying it in a simple and interpretable manner.
