A spatial and temporal distribution analysis of TCA biosynthesis phenomenon in the cork, through the use of both analytical data of sensory type and other instrumental determinations, was performed. By means of the sensory analysis, following the methodology of ISO 20752/2007 (E), it was determined the number of TCA-positive stoppers released and the percentage of caps with different defects. In each batch of caps, different scents have been identified: corked taste, mold, abnormal odor and doubt. The processed data from sensory analysis were broken down by geographic distribution and related to the instrumental determinations.
