Interest in the VisNIR spectroscopy for global characterisation of the ripening of cabernet franc

In the wine sector, it is allowed that the quality of the wine bases widely on the quality of the grape at the time of the grape harvests. Today, the only evaluation of the technological parameters of classic maturation (sugars and acidity) is not sufficient. The research for new indicators of maturity and new fast and not destructive measures are stakes waited by the professionals. The spectroscopic methods can be an effective alternative in the traditional analyses. In this context, the works led by the laboratory GRAPPE is to approach the maturity of the grape through an approach multicriteria basing on the reproduction of the methods of measure. We suggest presenting in this work, the results obtained to characterize the global quality of the grapes of Cabernet franc by means of the visible/ near infrared method.
