ELECTROANALYTICAL METHODS FOR PREDICTING THE OXIDABILITY OF A WINE OR A GRAPE MUST AND RELATED SYSTEMS

摘要

An electroanalytical method for predicting the oxidability of a wine or a grape must is disclosed. This example includes recording an electrochemical signal of a sample of the wine or grape must; comparing an electrochemical signature of the electrochemical signal obtained in a) with reference curves of voltammograms obtained from wines or grape musts with known oxidability; and predicting the oxidability of the sample tested based on the comparison. Markers for predicting the oxidability of a wine or a grape must and the use of electrochemistry for predicting the oxidability of a wine or a grape must are also disclosed. A method for predicting the optimal total oxygen supply for storing a wine or a grape must in a container; a method for wine maturation and/or ageing and; a method for selecting an optimal closure for storing a wine or a grape must in a container are also disclosed.
