Champagne Cork Extraction

Champagne and sparkling wine bottle cork extraction requires a specific helical motion and the ability to measure the peak torque.

Solution
  • CombiCork torque extraction system featuring specific bottle-gripping fixtures

Benefits
  • Quantitative test method

  • Increased repeatabiity

  • Confidence for cork manufacturers and users

The CombiCork 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.

Requirement

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.

Solution

The partnership between the technical and research teams from Mecmesin and Oeneo Bouchage helped to develop the CombiCork Extraction Tester, specially designed in order to test sparkling wine corks. The CombiCork Tester provides mechanical accuracy and is used to optimise extraction force measurement with three main advantages:

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

The CombiCork Extraction Tester includes:

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

CombiCorkCork extraction tester

Sparkling wines
CombiCork-dV

The CombiCork-dV is a purpose-built tester to reliably and objectively measure the release torque when extracting a cork from a sparkling wine bottle. The closure is extracted with a representative helical motion; combining twist and pull.

Its innovative bottle clamping design makes it quick and easy to carry out batch testing of champagne corks fitted to bottles ranging in size from 25cl to Magnum.

Still wines and spirits
CombiCork-i

The CombiCork-i is a purpose-built tester to reliably and objectively measure the both the pull-out force and release torque when extracting a cork from a still wine or spirit bottle. The closure is extracted with a representative helical motion; combining twist and pull.

Its innovative bottle clamping design makes it quick and easy to carry out batch testing of capsulated 'bar-top' design corks and stoppers fitted to bottles in a wide range of sizes.

CombiCork dedicated force and torque stopper extraction tester for still wines and spirits

The CombiCork is a purpose-built tester to reliably and objectively measure the release torque (and optionally the pull-out force) when extracting a cork from a sparkling wine or spirits bottle.

Its innovative bottle clamping design makes it quick and easy to carry out batch testing of champagne or capsulated (‘bar-top’) corks fitted to bottles ranging in size from 25cl to Magnum.
