DIAM Celebrates 20 Years of Protecting Wine Aromas in Rioja

  • In a tent-like space with a white fabric roof and decorative pennants, several people chat around a high table. On the table are glasses filled with sparkling/rosé wine and bottles, while in the background a large welcome sign reinforces the festive and celebratory atmosphere.

The company commemorates two decades of oenological innovation, leadership in oxygen control and strategic ally in preserving the identity of wine.

DIAM celebrated its 20th anniversary in Rioja with an event that brought together clients, institutions, and industry professionals to commemorate two decades as the “guardian of aromas.” The gathering combined gastronomy, live music, and a roving magic performance, highlighting a trajectory that has marked a turning point in the evolution of bottle aging and the protection of aromatic profiles.

The event also reaffirmed Diam Bouchage's role as a strategic partner for wineries, providing precision, reliability, and the guarantee of preserving the wine's identity. At the Villa Lucía gastronomic venue in Laguardia, attendees enjoyed an informal dinner paired with a selection of international wines, all sealed with DIAM closures. These wines demonstrated the organoleptic safety, sensory neutrality, and oxygen control characteristic of the company's closures—qualities that have solidified DIAM's position as a global leader in the wine industry.

Two Decades of a Revolution

François Margot, Sales and Marketing Director of Diam Bouchage, briefly reviewed the history of DIAM and its innovative DIAMANT® process, which eliminates the TCA responsible for "cork taint" and allows wines to evolve in the bottle without alteration, preserving their aromas and the profile desired by the winemaker.

For the past 20 years, the company has guaranteed TCA-free corks with exceptional sensory neutrality, offering unprecedented organoleptic safety. Thanks to its specific manufacturing technology, DIAM precisely controls oxygen transfer through each cork, ensuring homogeneity in every bottle and transforming the cork into a winemaking tool that allows for adjusting the wine's evolution according to its aromatic profile and aging potential.

With more than 20 billion bottles corked, DIAM has established itself as an international leader in oxygen control and homogeneity in wine evolution, offering solutions tailored to each style and aging period.
