OPLS-DA multivariate statistical analysis score plots generated from ¹Hwater_presat NMR data matrix (Figure 1) considering wines’ (A) and mezcals’ (B) ageing and manufacturing processes described in Table 1 and Table 2. T2 Hotelling’s ellipses have a 95% confidence level. Prediction accuracy curves as a function of PLS components, permutation tests, PCA analysis obtained from the same NMR data matrix and OPLS-DA loading plots of wines’ and mezcal’ analysis can be consulted respectively in Figures S6 and S7.
