Guide No. 6 - Metallic screw capping for still wines on BVS type glass finishes

This Guide gives information on good practices for bottling still wine with aluminium screw caps on a BVS-type glass finish according to EN 16293 - PACKAGING - GLASS PACKAGING - DEEP BVS FINISHES FOR STILL WINES, with a redraw while the cap application..
For this Guide, wine is considered to be "still" with a CO2 content < 1,2 g CO2/l (as defined in EN 16293).
The Guide defines:

The functions of the closure and its limits,
The specifications of each of the components are related to each other, to fulfil the global functions within determined limits.

Note that possible defects of applied closures and troubleshooting methodology are described in Cetie Guide N°11 - METALLIC SCREW CAPPING DEFECTS - IDENTIFICATION AND CORRECTION.

This joint group aims to coordinate the production of documentation at the junction of glass container production and closure application. It accompanies the development of documentation for glass containers for different types of closures including, but not limited to, aluminum screw caps, crown caps, and their components (liners). This joint group also provides an opportunity for cap and liners manufacturers to open discussions on specific work items of the permanent glass groups
