Solid-phase microextraction (SPME) coupled to capillary gas chromatography-mass spectrometry (GC-MS) was used for determination of volatile wine components. This combination offers a simple, quick, and sensitive approach suitable for characterization of wine aroma compounds without a complicated sample preparation procedure. Wines are characterized by "aromagrams", a set of identified components with corresponding relative abundances. Reproducibility (RSD errors of relative peak abundances) due to the analytical procedure are ca. 4%; variations among different samples of the same type of wine from the same region are ca. 8%. SPME-GC(-MS) has been shown to yield far larger differences among different wine types (Chardonnay, Muscat Ottonel, and Tramini) and among the same type of wine produced in different regions, showing the utility of the technique in wine analysis.
