外文摘要：Three Sauvignon Blanc wines sealed with seven closure types (natural corks, three microagglomerate corks,synthetics and two screw caps) were analyzed after 12 years of aging. OTR (oxygen transfer rate) of old stoppers(12 years) were determined by a strandardized protocol using coulometry. The other analytical markers werevolatile thiols and Strecker aldehydes determined by gas chromatography coupled with tandem mass spectrometry.Sulfites, dissolved CO_2 measurements and sensory analysis of the wines were also carried out. Weshowed that the OTR value changed after 12 years and the variability depends on the type of stoppers and rangedfrom 0.05 to 89.11 mg/year. The molecular markers analysed made it possible to illustrate the sensoryperception of the evolution of this wine. Molecular characterisation revealed that an average OTR_(12years) of0.27 mg/year allows preservation of thiols while delaying the formation of Strecker aldehydes whereas beyond0.82 mg/year in average, wines develop first signs of oxidation.
