PCA score scatter plot of the model obtained for the metabolites detected by HPLC-ESI-MS. Samples, corresponding to the seven vineyards (sampled in vintages 2006, 2007 and 2008 at three time points) are roughly separated according to developmental stage (a; explained variance equal to 44 %). Stage 1: beginning of véraison; stage 2: pre-ripening; stage 3: full maturity. PCA score scatter plot of the same data set used in (a) colored according to vintage (b; explained variance equal to 20 %). Blue: 2006; green: 2007; red: 2008. PCA score scatter plot of fully-ripe grapes (c; explained variance equal to 35 %). Blue: 2006; green: 2007; red: 2008. Vineyards:  = AM;  = BA;  = BM; ✦ = CS; ♦ = FA;  = MN; ▲ = PM
