Colmated Natural Cork Stoppers

Colmated stoppers are natural cork stoppers with pores (lenticels)that are filled with the cork powder resulting from the finishing of natural stoppers. A glue based on natural resin and natural rubber is used to fix the dust in the pores. A water-based glue is also currently used in this process.

This process is primarily used to improve the visual aspect of the stopper and its performance.

These stoppers are of quite homogenous appearance and have good mechanical characteristics. They are fabricated in the widest range of shapes and sizes. However the most common cylindrical form and sizes are those indicated below (length x diameter), although these may vary from one manufacturer to the next.
