Abstract
The invention concerns a method and a device for the objective qualitative analysis of liquid vinification compositions, comprising memory means (8) in which are recorded calibrating values of spectroscopic criteria for a group of characteristic parameters comprising the concentration levels of at least a compound produced by Botrytis cinerea, at least a compound produced by yeasts, at least a compound produced by the acetic bacteria, and at least a compound produced by lactic acid bacteria, means (1, 2, 3, 4, 6) for producing a continuous infrared spectrum, and means (7) for calculating the value (VP) of each characteristic parameter in the composition from the spectrum.
