surface treatment

Surface treatment adds a specially developed product to the stoppers, based on paraffin and/or silicone, which ensures that the stopper will slide smoothly when inserted into and extracted from the bottle. The surface treatment also provides other vital properties such as the reduction of capillarity and absorption of the drink through the stopper.

The stoppers used to seal spirit drinks are not compressed before being inserted in  neck of the bottle. The thickness of the stopper must always be adapted to the neck, in order to facilitate extraction. It must never be exerted by force, but rather with a slight “twist” and pull.
