Tapered Cork Stopper – 37mm /45mm

Tapered cork bungs are important tools used across many industries, particularly for sealing bottles and containers. Made from natural cork, they feature a tapered shape—broader at one end and narrower at the other—that ensures a tight, secure fit within a range of opening sizes. This design makes them highly adaptable for various types of bottles and containers. Cork’s natural characteristics, such as elasticity and impermeability, make these bungs perfect for forming airtight seals, essential for preserving contents and preventing contamination.

In home brewing, tapered cork bungs play a vital role. They are used to seal fermentation vessels, preventing carbon dioxide from escaping while stopping unwanted air and contaminants from entering. Maintaining this controlled environment during fermentation is crucial for achieving the desired flavour and quality of the brew. After fermentation is complete, these cork bungs are also used to seal bottles for storage, helping to keep the brew fresh until consumption. Additionally, cork’s natural antimicrobial properties assist in preserving the purity of the brew.

Outside of home brewing, tapered cork bungs have a wide range of uses. They are frequently employed in the wine industry for sealing bottles, where their ability to expand and contract with temperature changes helps to maintain the wine’s quality over time. Overall, tapered cork bungs are prized for their versatility, durability, and the natural advantages offered by cork.
