- Intervention effect Pre-veraison NAA treatment of Shiraz grapes delayed harvest maturity by 3-4 weeks.
- Intervention effect Pre-veraison NAA treatment of Cabernet Sauvignon grapes delayed harvest maturity by 3-4 weeks.
- Intervention effect Modification of nutrient accumulation by NAA treatment was minor.
- Intervention effect Wines made from NAA-treated and Control fruit showed no significant variation in basic chemical properties.
- Intervention effect NAA-treated Shiraz fruit and wine contained an elevated concentration of rotundone.
- Intervention effect The overall difference in wine volatile profiles between NAA and Control was small for both cultivars.
- Intervention effect Rate-All-That-Apply assessments found no sensory attributes distinguishing NAA and Control Cabernet Sauvignon wines.
- Intervention effect Rate-All-That-Apply assessments found few sensory attributes distinguishing NAA and Control Shiraz wines.
- Intervention effect The authors conclude that the NAA-induced effects are unlikely to negatively affect wine sensory perception.
