Thirty French red wines, selected from the main regions of France, were chosen as objects for an expert panel to be trained in Descriptive Analysis. Seventeen attributes were chosen to describe the wines. Principal Component analysis showed a good separation of the wines among regions of origin. The results were verified by Analysis of Variance (ANOVA). Generalized Procrustes analysis was included to analyze the panelist performance, such as individual differences in attribute ratings.
