oCPLS2-DA score scatter plot (a) and correlation loading plot (b) of the model for the metabolites detected by HPLC-ESI-MS. Samples, corresponding to seven grape vineyards at three developmental stages are separated according to the geographical macrozones, regardless of the vintage. Groups of metabolites are depicted in different colors. Vineyards: ▼ = AM; ● = BA; ◼ = BM; ✦ = CS; ♦ = FA; ★ = MN; ▲ = PM. aa = amino acid; ac = anthocyanin; flav = flavonoid; hb = hydroxybenzoic acid; hc = hydroxycinnamic acid; oa = organic acid; pr = procyanidin; s = sugar; st = stilbene and viniferin; ui = unidentified
