Since Excellent Cork began, our greatest concern has been the preservation of all qualities of the wine in all aspects of aroma and flavour. The S Series offers a robust stopper, intended for export wines and wines which may be consumed up to 48 months after bottling.

The manufacturing process with the individual mould injection system guarantees that the density and measurements of the stopper are consistent for all units, which is impossible to achieve with other systems such as extrusion or coextrusion.

Secure is the word which best defines the S Series.
