- Intervention effect Water deficit significantly reduced berry fresh weight, primarily through lower pericarp weight.
- Intervention effect Water deficit decreased pericarp weight.
- Intervention effect Water deficit increased grape anthocyanin concentration per berry fresh weight.
- Intervention effect Water deficit increased grape flavonol concentration per berry fresh weight.
- Intervention effect Irrigation treatments did not affect skin-derived tannin concentration in grape berries.
- Intervention effect During fermentation, wine anthocyanins were highest for non-irrigated and low frequency-irrigated grapevines.
- Intervention effect During fermentation, wine flavonols were highest for non-irrigated and low frequency-irrigated grapevines.
- Intervention effect Finished wines from non-irrigated and low frequency-irrigated vines had more bisulphite-resistant pigments than high frequency-irrigated vines.
- Intervention effect Finished wine phenolic composition differed only slightly between irrigation treatments.
- Association Higher bisulphite-resistant pigments were associated with vitisin A increases in the first season.
- Association Higher bisulphite-resistant pigments were associated with polymeric pigment increases in the second season.
- Intervention effect Eighteen months of wine ageing increased bisulphite-resistant pigments.
- Intervention effect Ageing enhanced irrigation-treatment differences in wine colour density.
- Intervention effect After ageing, wine colour density was higher in non-irrigated and low-frequency-irrigated treatments.
