Diam Cork is a leading brand that specializes in the design, production, and distribution of technological cork stoppers for still, sparkling, and spirits wines. More than just a mere closure, the cork stopper represents the final winemaking act for the winemaker. It plays a crucial role in preserving the wine's correct evolution inside the bottle during aging while maintaining the desired aromatic profile.

To ensure the highest quality, Diam Cork's dedicated teams work tirelessly on mechanical performance, sensory neutrality, and oxygen control in their products. At Diam Cork, innovation is at the heart of their expertise. The company has invested heavily in research and development, resulting in revolutionary and patented procedures.

In 2003, they introduced the groundbreaking DIAMANT® procedure that uses supercritical CO2 to remove volatile components from cork, eliminating the risk of cork taint. Building on this success, Diam Cork recently unveiled Origine by Diam®, a cork that combines science and nature with an emulsion of beeswax and a binding agent made from 100% vegetable polyols. With an impressive track record and global presence, Diam Cork is the world leader in technological cork stoppers.

They sell an astonishing 2. 7 billion corks annually, supplying more than 16,000 active customers in over 80 countries. As a subsidiary of Oeneo, a group dedicated to the wine industry, Diam Cork ensures that they care about your wine
