Still wines bottling - Synthetic stopper application on a cork mouth finish
Scope of application
This document applies to the bottling of still wines with a synthetic cork stopper on a cork mouth finish as per the European standard EN 12726 - PACKAGING - CORK MOUTH FINISH WITH A BORE DIAMETER OF 18,5 MM FOR CORKS AND TAMPER EVIDENT CAPSULES.
it sets down different tests, measures and precautions to be observed to ensure optimum performance during the capping of still wines with synthetic stoppers in a cork mouth finish as per Cetie data sheet GME50.01 - CORK MOUTH FINISH FOR CORKS AND CAPSULES (Standard EN 12726).
When used on other finishes, specific tests are to be set up.

Document under responsibility of working group:
Guide N°17 creation
WG chair: Christophe ROBERT - VINVENTIONS S.A. BELGIUM
The working group on Guide No. 17 is dedicated to bottling still wines using synthetic closures containing less than 50% cork. This topic, initially covered in Guide No. 1 - Still wines bottling - cork stopper application on a cork mouth finish, was addressed separately during its revision, completed in early 2024, and is now the subject of a dedicated document. The objective is to identify the specific characteristics of synthetic closures, define their functions and limitations, and establish appropriate application conditions to ensure optimal bottling. This work also includes the revision of fact sheet EC3.01 on best practices for using synthetic closures, providing professionals with a precise and tailored technical framework.
