Dr. Joanna Gambetta has studied in Peru, France and Australia. She has a Master’s degree from Montpellier SupAgro in oenology and viticulture and a PhD in wine science from the University of Adelaide.
Her PhD project focused on the determination of objective parameters to assess the quality of Chardonnay grapes, juice and wines. She works now at the National Wine and Grape Industry Centre at CSU where she is pursuing her interest in the aroma composition of grapes and wines in relation to different biotic and abiotic stresses.
Specialisation: Grape and wine chemistry
Focus area: Grape and wine composition in relation to biotic and abiotic stress.
The global climate is changing, resulting in higher temperatures, increased variability in climate patterns and water deficits. Higher temperatures affect vine physiology and change the normal patterns of grape development, which translates into earlier véraison dates and berry ripening during the hotter part of the season. Understanding the effects of heat on the formation of aroma volatiles of grapes by using targeted and untargeted techniques will allow producers and researchers to develop effective strategies to mitigate the effects of short- and long-term climate cycles and reduce economic losses due to lower quality fruit and wine.
