Effect of different liquid-to-solid ratios (a), temperatures (b), and methanol proportions (c) on total phenolic (TPC), total anthocyanin (TAC), and total flavanol (TFC) content in organic whole red Grenache grapes. The results are expressed as mg of phenolic equivalents per gram of dry weight (mg Eq/g dw) ± SD (n = 3). Letters represent significant differences (One-way ANOVA; p < 0.05). Abbreviations: liquid-to-solid ratio (LSR), methanol (MetOH), gallic acid equivalents (GAE), malvidin-3-O-rutinoside (Mv3R), and catechin (Cat).
