O-I redesigns the packaging of Metodo Classico sparkling wines: lower weight, same performance

O-I specialising in the production of glass packaging for the wine and food & beverage sector, has introduced a solution of 75 cl for Metodo Classico sparkling wines that optimises the distribution of glass at 795 g, placing structural performance and perfect integration with existing production processes at the centre.

Until now, bottle lightweighting projects for Metodo Classico have often required wineries to accept complex technical compromises or make costly modifications to their packaging lines. O-I's engineering solution overcomes this limitation, demonstrating that it is possible to improve efficiency of the containers while maintaining full compatibility with traditional and automated workflows.

Technical features

The technical challenge overcome by O-I lies in the management of the bottle's external geometry. Through meticulous co-design and structural simulation, the engineering team reduced the weight while keeping the critical contact points unchanged of the profile:

• No impact on riddling: The bottle's silhouette differs by only a few millimetres from conventional, heavier models. This allows wineries to use the same handling cages and riddling systems already in place, eliminating the need for additional investment.
• Mechanical strength: The bottle is designed to withstand, in complete safety, the stresses generated by secondary fermentation in the bottle, guaranteeing internal pressure resistance equal to that of standard-weight containers.

“The meeting of design and advanced engineering gives rise to innovative solutions developed on an industrial scale”, comments Ernesto Ghigna, O-I's Europe marketing leader. “In our sector, innovation lies in the ability to transform technical complexity into real value: technological, industrial and brand value. That is what we have done with this new solution for Metodo Classico, which guarantees maximum structural reliability and full process continuity for wineries, confirming our role as a strategic partner in developing ready-to-use solutions for the wine market.”

A more sustainable solution

Optimising the bottle's weight without altering its performance means using less energy to melt less glass and reducing overall CO2 emissions by approximately 5% . For wines that require years of ageing before reaching their fullest qualitative expression, packaging thus evolves into a tool for protection and industrial efficiency, combining technical robustness with the category's premium positioning.
