An optimized method of purge and cold trapping injection-capillary gas chromatography was applied to the analysis of some volatile constituents of Galician (northwestern Spain) white wines with certified brand of origin "Rias Baixas" and other white wines produced in neighbor regions in order to obtain their volatile profile. Identification of the chromatographic peaks was performed by coupling an ion trap detector to the chromatograph. Characterization of Rias Baixas wines was performed applying nonsupervised and supervised multivariate techniques of analysis (cluster analysis, principal components analysis, K-nearest neighbors). Thus, multivariate profiles of the wines were obtained, and certain differences between Rias Baixas wines and other Galician wines could be observed. Some atypical wines in both categories were pointed out by the exploratory and classification methods.
