A Chemometric And Sensory Study Of Spanish Red Wines Labelled “Tempranillo Crianza 2010” With Protected Designation Of Origin Quesada Granados, José Javier Spanish protected designation of origin Red wine Tempranillo Crianza Chemometric study Sensory study A chemometric and sensory study was conducted of ten Spanish red wines, all described as “Tempranillo Crianza 2010”, with Protected Designation of Origin (PDO). The analysis considered the following physicochemical parameters: alcohol content, SO2 level, acidity, tannin, antioxidant capacity and colour. In the chemometric study, Principal Component Analysis of the colour, Cluster Analysis, Analysis Of Variance (ANOVA) and the Kruskal-Wallis test showed that the samples corresponding to PDOs #8, #9 and #10 presented the highest number of differences from the rest. In the sensory analysis, Samples #9 and #10 were identified as the most different. From both types of study, we conclude that Samples #8, #9 and #10 present the greatest differences, while the remaining samples were very similar in their chemometric and sensory characteristics. 2024-06-24T07:37:03Z 2024-06-24T07:37:03Z 2024-10 journal article A chemometric and sensory study of Spanish Red Wines labelled “Tempranillo Crianza 2010” with Protected Designation of Origin.
