Diam corks – the ultimate solution for managing oxygen levels during wine aging. Oxygen is a vital component in the aging process, and finding the right balance is key. With Diam corks, winemakers can achieve precise controlled oxygen management throughout the journey. During the initial stages of wine aging, Diam corks gradually release oxygen inside the cork, known as Oxygen Initial Release (OIR). After 6 months, the oxygen gradually moves from the outside of the bottle, passing through the cork and entering the inside of the bottle, known as Oxygen Transfer Rate (OTR).). This phased oxygen control empowers winemakers to fine tine the development of their wine’s profiles during the maturation process. Diam offers a range of cork options, including Diam 2, 3, 5, 10, and 30 with different OIR and OTR values. This flexibility allows winemakers to choose a cork that guarantees a long lifespan while also accelerating the aging process for earlier consumption. Discover the power of Dia

The NEOTECH® process uses controlled steam and pressure to expel the TCA and other volatile compounds from the cork granules. We use this process to ensure high quality in Silktop®
