About

About Diam Closures Diam Bouchage designs, manufactures and markets technological cork closures for still wine, sparkling wine and spirits. So much more than a simple stopper, the cork is the last oenological act of the winegrower. It must enable the wine to fully develop in the bottle throughout the ageing period and maintain the aromatic profile sought for a particular wine. This is why the teams at Diam Bouchage work each and every day to ensure the quality of the company’s products in terms of mechanical performance, sensorial neutrality and oxygen control.
