Chromatographic profiles and mass spectrometric data for more than forty various types of brandies, cognacs and armagnacs were obtained using gas chromatography coupled with mass spectrometry (GC/MS). Twenty-three characteristic compounds were identified by means of mass spectral libraries and integrated using selected m/z ratios. Some indexes related to consumer properties of drinks were calculated. The quality and the origin of examined brandies were evaluated using the GC/MS data.
Key words: brandy / quality control / index of age / syringaldehyde / vanillin ratio / level of esters of superior acids
