Diam Cork is a renowned brand that specializes in producing and marketing technologically advanced cork closures for still wines, sparkling wines, and spirits. More than just a simple stopper, the cork is the final oenological act of the winemaker, ensuring the proper evolution of the wine in the bottle while preserving its desired aromatic profile throughout its aging process. Diam Cork's dedicated teams work tirelessly to ensure the quality of their products, focusing on mechanical performance, sensory neutrality, and oxygen control.

With a strong commitment to innovation, Diam Cork invests significantly in research and development, resulting in groundbreaking advancements such as their patented DIAMANT® process. This revolutionary technique, based on supercritical CO2 extraction, effectively eliminates volatile compounds from the cork and eliminates the risk of cork taint or undesirable aromas. Additionally, Diam Cork recently introduced Origine by Diam®, a technologically advanced cork that combines science and nature, featuring a beeswax emulsion and a 100% vegetable-based binder.

As a global leader in technological cork closures, Diam Cork sells around 2. 7 billion closures annually, experiencing a remarkable 10% growth in value in 2019/2020. With over 16,000 active customers and distribution in more than 80 countries, Diam Cork truly values the customers and strives to uphold their mission: We Care About Your Wine.
