G3 Diam Corks: Leading Technological Wine Closures in California

G3 Diam Corks provide winemakers with a revolutionary closure solution that guarantees absolute protection against TCA (cork taint) and other off-odors. Distributed in North America through the technical partnership of G3 Enterprises and Diam Bouchage, these micro-agglomerated closures are crafted using a patented supercritical carbon dioxide cleaning process, ensuring that the natural profile of each vintage is kept intact.

Symmetrical Oxygen Control with Diam Origine

Controlling the aging process requires closures that offer consistent, predictable oxygen transmission rates over several years. G3 Diam Corks are available in ranges designed for different cellar-aging periods, such as Diam 2, 3, 5, 10, and 30. For a sustainable option, their eco-friendly Diam Origine corks incorporate a natural beeswax emulsion and plant-based binders, ensuring minimal environmental impact while preserving the wine’s freshness.

Guaranteeing Quality and Bottle Consistency

Cool-climate white wines and delicate Pinot Noirs produced in California require precise preservation to maintain their bright fruit and crisp acidity. G3 Diam Corks offer structural symmetry that prevents irregular bottle variation, ensuring every consumer enjoys the exact sensory profile intended by the enologist. This level of technical security makes Diam the preferred closure for premium boutique wine producers.
