A non-destructive method for analyzing a cork stopper for the presence of 2,4,6-trichloroanisole. The stopper is introduced into a hermetically closed container. The container containing the stopper is heated under conditions vaporizing any 2,4,6-trichloroanisole present in the stopper. A gaseous sample of the atmosphere surrounding the stopper in the container is collected and analyzed for the presence of 2,4,6-trichloroanisole. This method allows the selection, in a batch of cork stoppers, of the stoppers that are substantially free of 2,4,6-trichloroanisole, in a non-destructive manner.
