Quality and Guarantees. ISO Certificates. 

Our analysis and control methods are extremely stringent and set the standards that ensure the product’s final quality.


Controls: All of the stoppers go through exhaustive quality controls. Each manufacturing batch is analysed by our internal laboratory and by independent, external laboratories such as LABORATORY EXCELL and LABORATORY CORK CENTER, etc.


Analysis: all kinds of analyses are performed: size, density, moisture, sensory, overall migration, microbiological, extraction force, residual dust, residual peroxides, waterproofing, TCA and bottling tests. We have the equipment needed to carry out tests related to UNE and ISO standards and current European regulations.

Our manufacturing facilities and processes have been recognised and approved by Certificación IMQ Ibérica as complying with the ISO 9001(Quality management systems) and ISO 22,000 (Food safety management system) standards
