LiOX by Diam, a clear solution to the challenges of oxidation

Desorbed closure for sparkling wines

Thanks to an optimized desorption process, the LiOX closure releases half as much oxygen during the critical Oxygen Initial Release (OIR) phase as conventional Mytik Diam stoppers.

A major breakthrough in oxygen control

logotype liox

Thanks to an optimized desorption process, the LiOX closure releases half as much oxygen during the critical Oxygen Initial Release (OIR) phase as conventional Mytik Diam stoppers. This upstream control limits the initial oxidative shock associated with the closure and counteracts the risk of premature oxidation, while maintaining the recognized mechanical performance of the range.

Winner at VITeff 2025, LiOX by Diam continues Diam Bouchage's heritage of innovation, more than twenty years after the Diamant process was recognised. It represents another step towards precision winemaking that is sustainable and adapted to climate challenges.

An innovation emerging from consultation with the Champagne industry

cellar masters and independent winegrowers

LiOX by Diam embodies a collaborative and scientific approach to innovation that has been developed following extensive consultation not only with cellar masters and independent winegrowers but also with the Champagne Committee on the enological requirements for closures.

50% OIR reduction

An unprecedented performance

Thanks to an optimized desorption process, the LiOX closure releases half as much oxygen during the critical Oxygen Initial Release (OIR) phase as conventional Mytik Diam stoppers. This upstream control limits the initial oxidative shock associated with the closure and counteracts the risk of premature oxidation, while maintaining the recognized mechanical performance of the range. LiOX by Diam is the ideal solution for anyone who wants to prioritize the aromatic freshness of their wines.

Oxygen control 

for sensitive wines

In a context of global warming and reduced inputs, controlling oxygen has become essential to guarantee the natural stability of less protected wines. This new closure solution is also perfectly suited to wines that are sensitive to oxidation: sparkling rosés, half bottles, and wines with low sulfite content.

A cork that is always guaranteed Mytik Diam

By acting upstream, during bottling, the LiOX cork acts as an active barrier against premature oxidation while maintaining the guarantees of safety, homogeneity and adaptability that have made the Mytik Diam range so renowned. Unrivalled sensory neutrality with no risk of cork taint, perfect mechanical consistency with no bursting of washers or dowels after bottling, and controlled gas exchange management for slow and consistent maturation.
