Oxygen Ingress Study

Assessing the real contribution of closure to oxygen ingress in the bottle

The 1st and unique rapid method for oxygen ingress measurement of the wine industry, stemming from years of dedicated research, making it our core expertise.

Assessing the closure and other packaging performances in terms of oxygen permeability

Managing oxygen ingress through closure selection contributes to modulate the aromatic evolution of wine and avoid reduction or oxidation. Our method considers both oxygen transfer rate (OTR) and outgassing, offering a reliable measurement for any type of closures. Winemakers can now assess closure performance, identify variations, and make informed selections based on their objectives.

Main features

Versatile Measurement

The method measures closure oxygen ingress in natural corks, cork-based stoppers, and mono or co-extruded closures, providing winemakers with a comprehensive assessment.

Non-Destructive and Efficient

Utilizing NomaSense O₂ P6000 analyzer, the measurement is non-destructive, allowing quick results in two to three weeks, in comparison to the Mocon-Oxtran method.

Consistency Analysis

The method evaluates cork-to-cork variations within the same batch and across batches, ensuring consistency assessment in closure performance

Packaging Permeability Study

Besides closures, the method assesses the permeability of other packaging options like Bag-In-Box® and wax seals, offering valuable insights for packaging choices.
