A cork closure at the service of your wine

« 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. »

Dominique Tourneix, C.E.O.

Diam Bouchage has always been an innovative company; every year, it allocates a substantial budget to research and development.
In 2003, the company began investing in a revolutionary, patented process, called the DIAMANT® process that uses the properties of supercritical CO2 to extract the volatile compounds of cork and eradicate the molecules responsible for giving a taste to the wine, especially those causing “cork taint”.
Twelve years later, the company made yet another breakthrough in major technological progress with the launch of Origine by Diam®, a closure that reconciles science and nature, integrating a beeswax emulsion and binding agent composed of 100% plant-derived polyols.
