Technical Corks "Diam"

Diam is a technological closure with a patented composition, which is manufactured from cork and treated by the patented DIAMANT process. Validated by several worldwide independent laboratories, the DIAMANT process uses super-critical CO2 to eradicate 2, 4, 6 – trichloroanisole (TCA) and 150 other compounds. Each Diam cork is guaranteed to have no TCA (below the detectable TCA ≤ 0.3 ng/l).

Ranging from Diam 2, Diam 3, Diam 5, Diam 10, and the new Diam 30, Diam offers a clean and consistent product where the cork is sensorial neutral.
