e0“Post-veraison irrigation increased yield parameters and reduced anthocyanin levels and the proportion of their stable forms (acylated vs. non-acylated, tri-oxygenated and methoxylated on the B-ring vs. di-oxygenated and hydroxylated), compared to NI vines; however, these effects were more pronounced in the case of early post-veraison irrigation (AVI) than late-season irrigation (MRI).”

- Intervention effect Post-veraison irrigation reduced anthocyanin levels versus non-irrigated vines, more strongly with AVI than MRI.
- Intervention effect Post-veraison irrigation reduced proportion of their stable forms versus non-irrigated vines, more strongly with AVI than MRI.
- Intervention effect Irrigation increased mean Degree of Polymerization (mDP) of skin tannins.
- Intervention effect Irrigation increased prodelphinidin percentage of skin tannins.
- Intervention effect Irrigation decreased mDP of seed tannins.
- Recommendation Late irrigation might avoid excessive sugar levels, allow slightly higher yield, and avoid significant loss of berry phenolics.
- Recommendation Optimizing irrigation timing may aid climate adaptation in Mediterranean viticulture.
