Safety Cork for 1G & 5 G Demijohns

The safety cork has a one-way valve to protect finished wine from spoilage when stored in 1gall. or 5gall. containers.

A demijohn is a large glass container often used for fermenting and storing liquids such as wine, cider, or beer. It typically comes with a rubber or silicone bung that fits tightly into the mouth of the demijohn to prevent the contents from leaking or being exposed to air.

Demijohn safety cork is a bung / plastic stopper designed to release pressure in a container to prevent explosions or other dangerous situations. 

Safety corks are often used in the wine, champagne, and beer industries, where the carbon dioxide produced during fermentation can cause the bottle to become pressurized.

There are several types of safety stoopers, including those with a plastic or metal valve that will release pressure when it reaches a certain level or those with a weak point in the cork itself that will break under pressure. This demijohn safety corks is designed to be reusable, while others are intended for one-time use only.

Overall, the use of a container bung can help ensure that the contents of a bottle remain safe and free from the risk of explosion or other hazards

 Here are some tips for choosing and using a safety dung for home brewing:

  1. Use a high-quality bung that fits snugly in the fermenting vessel's opening. Make sure it is made of food-grade material and is the right size for your container.
  2. Choose a bung that has a pressure-release valve or a blow-off tube. This feature allows excess gas to escape, preventing the bung from popping out or the container from exploding.
  3. Clean and sanitize the bung before use. This will help prevent contamination and ensure that no harmful bacteria or other microorganisms can grow in your brew.
  4. Check the bung periodically during fermentation to ensure it is still secure and functioning correctly. If you notice any issues, such as the pressure-release valve not working correctly or the bung fitting too loosely, replace it immediately.
  5. Store your bung in a clean, dry place between uses. Avoid exposing it to extreme temperatures or sunlight, which can damage the material and reduce its effectiveness.

By following these suggestions, you can help ensure that your homebrewed beer or wine is safe to drink and free from any harmful contaminants.

Hold the container securely when handling a demijohn with a bung in place and avoid dropping or bumping it. Rough handling could cause the cork to dislodge or break, potentially resulting in spillage or injury. It is also a good idea to store the demijohn in a cool, dry place away from direct sunlight to help preserve the quality of the contents and reduce the risk of breakage or other damage.
