Üsna palju veini läheb raisku korgivea tõttu, mida enamasti põhjustab TCA. TCA on looduslik seen, mille kirbe seene- ja kopituse lõhn varjutab kõik veini aroomid. TCA-d võib leida korgipuu koorest, millest suur osa veinikorke valmistatakse.
Molds are considered the most significant causative organisms of cork taint, with implicated genera including Penicillium, Aspergillus, Cladosporium, Monilia, Paecilomyces, and Trichoderma. However, the chemistry of cork taint is complex, and the biochemistry of the organisms involved is not fully understood.
