Diam’s Revolutionary Cork Closure Technology

  • International Bulk Wine and Spirits Show

Diam Bouchage manufactures technological cork closures for still wine, sparkling wine, and spirits. Diam’s revolutionary technology eliminates TCA and up to 150 molecules, guarantees cork elasticity, and controls how much oxygen penetrates the cork. The mechanical properties of Diam corks, ranging from 2 to 30 years, guarantees winemakers consistent aging from one bottle to another. Diam’s sustainable corking solution, Origine by DIAM®, is a bio-sourced cork that offers different permeability options to control wine aging with ranges from 5, 10, and 30 years for still wines. Diam Mytik offers improved aging and preservation of CO2 pressure over time, giving winemakers more control throughout the process. G3 Enterprises, a leading beverage supply chain and logistics provider, is the sole distributor of Diam products in North America.
