Potentiality of the cyclic voltammetry for the assessment of the wine evolution
Piergiorgio Comuzzo, DI4A, Università di Udine (I)
The cyclic voltammetry is an analytical technic, based on redox systems, that allows, if combined with multifactorial statistical analysis, an innovative approach to the wine oxidation study.
The voltammogram (obtained graph) enable us to have important information on the behavior of certain chemical families in a solution.
The presentation of Piergiorgio Comuzzo at Enoforum explains the potential of this analytical technique to characterize phenolic substances and to study oenological antioxidants on the basis of their reducing power. Together with data analysis based on multivariate analysis, the voltammetric approach has allowed to discriminate wines made of various variety as well as to find existing correlation between voltammograms and the oxygen consumption or the wine resistance to oxidation.
The paper reproduced in this video-seminar was presented at the 12th edition of Enoforum (Vicenza, Italy, May 21-23, 2019)

Wine is fundamentally a high-intervention product, and along all stages from harvest to bottling it's our job to guarantee safety and quality, but it's also up to us to research, experiment, and ad...
Producing a wine according to our oenological objective, wanting to express the variety, but adapting practices according to the sanitary status of the grapes, is continuous experimentation. We aga...
Phenolic composition of grapes has an important impact on the final intrinsic quality of (red) wines. Wine taste, mouthfeel and colour are driven principally by phenolic compounds present in grapes...
