The CombiCork extraction tester is used across the world by both cork manufacturers and producers of sparkling wines and spirits. It allows them to reliably check the suitability of different cork materials and designs, including the effects of any coatings and additives, for the openability of the bottle.
Traditional methods have relied upon corks being manually extracted by an operator with a subjective assessment of how difficult it was to do so. By using a tester which accurately replicates the helical extraction motion, objectively measures, indicates and reliably records the relevant release effort, this subjectivity is removed.
In the case of sparkling beverages, objectivity helps to resolve conflicts between the cork suppliers and the cork users over the relative difficulties in extraction. It is particularly important to avoid identifying an insufficiently low torque as a good indicator of a cork, which could then inadvertently explode out of the pressurised bottle and cause harm to the consumer.
The CombiCork creates the controlled test conditions to deliver a measurement repeatability which is difficult to achieve through subjective manual test methods.
