The approach uses commercially available solid-phase microextraction fibers for reduced pressure preconcentration and gas chromatography–mass spectrometry to detect TCA in wine bottle-mounted corks. Instrument calibration experiments and data corresponding to intentionally contaminated free and wine bottle mounted corks are described. This study suggests that reduced-pressure full-bottle screening is a viable qualitative method for identifying bottle-mounted TCA tainted corks without violating the bottle or harming the bottle seal and label.
