Is it true that cork taint is caused by the widespread use of pesticides in the 1950s and 1960s?
Some researchers believe the historical use of pesticides containing compounds such as pentachlorophenol may be contributing to the TCA problem. However, these chemicals have not been used for maintenance of the cork forests for many years. Amorim has 40-year-old purchasing records that help identify the best quality cork sources and Portocork’s manufacturing process is designed to thoroughly clean cork of all contaminants.
