Dominique Tourneix is the Director General of DIAM Bouchage, a company specializing in reconstructed cork closures for wine. Dominique discusses the causes of cork taint in wine and the presence of volatile compounds within traditional cork. He examines the part that wine cork plays in both preventing and allowing for the oxidation of wine, as well as the useful life of a cork. He also explains the alternative solution that his company offers to the traditional wine cork, and how it can be seen as a winemaking tool. Dominique further gives an overview of the global market for wine closures, comparing the relative attributes and market share of synthetic closures, screwcap, traditional cork, and reconstructed corks like DIAM.
