This episode of the Podcast features Francois Margot from DIAM Bouchage, a company that designs, manufactures, and markets technological cork closures. Our conversation covers the unique qualities of natural cork and the DIAM’s innovations that were developed to address cork closures’ mechanical performance, sensorial neutrality, and Oxygen control. Francois describes in great technical detail the production and performance of DIAM’s range of cork closures. This is not a podcast sponsored by DIAM. I have been using DIAM corks in the wines I am producing for Terratorium Wines and Naked Wines. Because of those associations I have been motivated to study the DIAM technologies and felt it valuable to share with the podcast audience.
