Summary The international development of FTIR systems is actually very important for wine and musts analysis. There are very efficient for the quantitative evaluation of many components of musts. This allows a pertinent approach of the maturity index of grapes and their technological potential. Authors showed also that an important information is present in the middle range infra-red spectrum of the musts. This information is connected to the metabolites produced by micro-organisms which can be present on grapes before ripening (Botrytis cinerea, Aspergillus carbonarius, yeasts and bacteria). The determination of this information and its statistic treatment allows a measurement of the true impact of the micro-organisms on the grapes quality. |
