One-way ANOVA section: different superscript lowercase letters represent statistically significant differences between the two investigated wines determined by one-way ANOVA at \(p\) < 0.05 for each harvest year separately. Two-way ANOVA section: designations are reported representing yeast (SCE, SPA) and harvest year (21, 22) with higher concentration determined by two-way ANOVA at \(p\) < 0.05 with yeast (\(\Upsilon\)) and harvest year (H) as factors. An asterisk indicates a significant interaction between the two factors (\(\Upsilon\times\) H). Significant differences are highlighted in bold.
