Oeneo Bouchage's Champagne cork extraction test is simplified by Mecmesin

  • Mecmesin

Cork extraction strength is mostly used in the development of uncorking solutions for Champagne and sparkling wines. It is critical to measure the extraction force of corks in order to maintain a balance between easy opening of bottles by consumers, whilst avoiding exploding corks.

When you wish to make multiple measurements, manual instruments can be too restrictive. Operators performing multiple tests may become fatigued, increasing the risk of injury through improper handling of the sample.


The partnership between the technical and research teams from Mecmesin and Oeneo Bouchage helped to develop the Combi Cork Extraction Tester, specially designed in order to test sparkling wine corks.

The Combi Cork Tester provides mechanical accuracy and is used to optimise extraction force measurement with three main advantages:

  • Special cork grip
  • Dedicated bottle fixture; easy-to-use and adjustable
  • Cork extraction test with pull and twist movement


The Combi Cork Extraction Tester includes:

Bi-directional motorised test system
Rotary torque sensor capacity 15N.m
Digital display AFTI
Grips and fixtures for corks and bottles


The Combi Cork Extraction Tester helped us to simplify measurements because it is easy to set up. This system provides consistent reproducible and safe measurements, without any risk of injury to the operator. Therefore, we can establish valuable opening torque specifications, which are currently used for quality control measurements and development of new products.

Cosmetic packaging pull-off test

A bench-top testing system was required to repeatably test the pull-off force on a variety of cosmetic containers. The system needed to allow a relatively high volume of containers to be tested with the minimum level of training required for users. Mecmesin's solution avoided the risk of damaging the loadcell by excessive torque on tightening the collet grip, and the lipstick barrel was first inserted in the grip and then connected to the gauge by a flexible chain-link.

Food packaging made from thermoformed plastics and intended for freezing, requires testing to ensure optimum functionality when closing and sealing the container. The closing effort of the lid is measured by using a motorised force tester controlled by software together with a custom-designed fixture to hold standard-sized ice cream tubs. In addition the ‘top-load’ crush strength of the container itself can also be tested on the same machine to guarantee it is rigid enough to avoid buckling and spillage when the lid is applied.

Mecmesin develops Combi Cork-i Extraction Tester for leading Scottish whisky

To improve the quality and storage of a premium product, the R&D team at a leading Scottish whisky maker needed to optimise the design of their bottle stoppers. They decided that the strength and performance of their reusable stoppers could be ensured by systematic testing of the characteristics of both portions of the stoppers. Working closely with the R&D team, Mecmesin developed the Combi Cork-i Extraction Tester, an innovative multi-function cork extraction testing system that tests both phases of de-corking synchronously.

Greek beauty product manufacturer guarantees production quality by updating to Mecmesin's digital torque testers

A manufacturer of a wide range of skin, hair-care, make-up and sun-care products based in Greece needed to replace their outdated torque testers with up-to-date digital torque testers to guarantee production quality and to ensure their products remained sealed. Mecmesin supplied the company with two Tornado 10N.m digital torque testers, which have the ability to test tamper-evident closures, an intrinsic part of their specification.
