Bottling guides

This guide applies to the capping of still wines with a cork mouth finish as per Cetie data sheet GME50.01 - CORK MOUTH FINISH FOR CORKS AND CAPSULES which has been used as a base for the European standard EN 12726 - PACKAGING - CORK MOUTH FINISH WITH A BORE DIAMETER OF 18,5 MM FOR CORKS AND TAMPER-EVIDENT CAPSULES.
If application is done on another finish, the user must carry out sealing tests to ensure that this application is technically acceptable.
The term “still wines” does not exist in the legislation. Still wines are defined as having a level of carbonation below 1,2 grams per litre of liquid, and for which the over-pressure due to carbon dioxide is below one bar in sealed containers when kept at a temperature of 20 °C.
For wines with a level of carbonation above 1,2 grams per litre of liquid (but below 2 000 mg), suitable stoppers must be used (diameter above 24 mm for natural cork, to be defined for other types of stoppers). 01/01/1992 - Latest update 01/01/2008

This guide gives information on good practices for bottling still products with aluminium screw caps (e.g. corresponding to specifications EC4.03 - ALUMINIUM SCREW CAPS FOR STILL LIQUIDS ON BVP GLASS FINISHES) on a BVP-type glass finish according to EN 15543 - GLASS PACKAGING - FINISHES FOR BOTTLES - SCREW THREAD FINISHES FOR BOTTLES FOR NON-CARBONATED LIQUIDS or equivalent.
 
The guide defines:

• The functions of the closure and its limits ;
• The specifications of each of the components 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 Bottling Guide N°11 - METALLIC SCREW CAPPING DEFECTS - IDENTIFICATION AND CORRECTION. 01/01/2006 - Latest update 11/03/2020

 This guide is intended for producers of quality sparkling wines who carry out the secondary fermentation process in the bottle, also known as bottle fermentation. These sparkling wines undergo two successive closure operations in the same bottle, a tirage (bottling) closed by a "bidule" and metal crown cap with synthetic liner, or by a cap with built-in bidule, followed by final corking with a traditional cork (agglomerated cork/two disks of natural cork) or a micro-agglomerated cork, held in place by a wire cage (or "muselet").
This guide can nevertheless be used by sparkling wine producers, for the parts that concern them, who use methods other than in-bottle secondary fermentation.
Please note that this guide does not cover tirage (bottling) or final corking using cork stoppers held in place by clips.
The conformity of the supplies, their conditions of use and the required verifications constitute the good practices to guarantee high-quality closures.
This guide is also intended to facilitate the diagnosis of malfunctions. For more detailed information on the various supplies (bottles, bidules, caps, corks, and wire cages), readers can refer to the guides specific to each of these supplies, if they exist, and to the suppliers' specifications.
This guide is the interprofessional reference document, but it can be supplemented by contractual specifications established between suppliers and users. 01/03/1994 - Latest update 31/07/2020

This document concerns the crowning process, using crown caps for which the seal is provided by a plastic liner, onto glass finishes adapted to either "pry-off" or "twist crown" applications. It mainly focuses on capping with crown caps designed with a 6 mm height and a 26 mm diameter, as defined in EN 17177 - GLASS PACKAGING - CROWN CAP - 26 MM DIAMETER, 6 MM HEIGHT CROWN CAP, onto glass bottles.
The main objectives of the document are:

• to provide manufacturers and users with a reference tool that can ensure the correct procedures for crowning and also the safety of the consumer;
• to give the specifications of each of the components and their interfaces;
• to provide manufacturers and users with a reference document for drafting specification sheets and quality assurance procedures;
• to simplify troubleshooting in the event of problems.

This guide represents the current situation and may be updated according to the development of new crowning technologies.
It has been drafted concerning those standards that are either current or in preparation and to other reference documents recognised in the industry, and identified as pertinent.   01/01/2002 - Latest update 28/09/2020

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. 01/01/2007 - Latest update 11/03/2020

This document applies to the screw capping of still wines with a metallic closure having a threaded plastic or aluminium insert and a tamper-evident band which needs to be snapped before it can be opened. The closure is screwed and crimped during capping. The application shall be done only on a BVS finish according to EN 16293 - PACKAGING - GLASS PACKAGING - DEEP BVS FINISHES FOR STILL WINES. standard. This provides a seal on the top and evenly on the side of the finish. The term “still wines” does not exist in the legislation. This category includes all wines except sparkling, nor soft or natural, etc, and for which the overpressure due to carbon dioxide is below one bar in sealed containers when kept at a temperature of 20°C. Still wines are defined as having a level of carbonation below 1,2 grams per litre of liquid. 01/01/2008 - Latest update 10/07/2023

This guide concerns screw capping of still wines with a threaded plastic closure having a tamper evident ring whose bridges must break on opening
The cap is screwed on after filling and can be applied on a screw finish in glass or PET of the BVS type. This operation enables a seal to be ensured on the top and sides of the sealing surface.

Note
The term “still wines” is not currently defined in legislation; it is generally accepted practice to consider “still” wines whose carbon dioxide content is less than 1.2 g per litre of liquid and which gives an overpressure of less than 1 bar relative when maintained closed at 20°C. Wines entering in this category are neither “sparkling” nor “sweet” nor “natural”, etc.  26/10/2015 - Latest update

This guide gives the necessary information on good practices for bottling wines and other products with a CO2 content > 1.2 g CO2/l with an aluminum screw cap on a BVS-type glass finish accommodating redraw of the application cap.
Both the cap and the bottle must be foreseen for the application, subject to a written agreement between the cap supplier, the bottle supplier, and the filler.
It remains the responsibility of the filler to ensure that the package is appropriately designed for the product bottled and foreseen conditions of storage and transport as well as to avoid risk of injury on opening.
Attention is drawn to the necessity to observe special precautions for carbonation levels above ~3 g/l CO2 or a pressure exceeding 6 bars.
This guide does not cover the use of MCA-type pressure caps or smaller diameter BVP-type caps/finishes used with redraw.
The Guide defines:

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

Every stage in the packaging of a product is part of good manufacturing practice, in the same way as its production.
The correct use of industrial glass jars and metal capsules is part of this principle.
It enables these two complementary elements to fulfill their protective packaging role to the full. This guide, which does not claim to be exhaustive, sets out the main rules to be observed.
As you will see, they are pragmatic and simple to implement. This document should not be considered as a regulatory text, but as a very general guide that can be adapted in certain specific cases.
