Practical rubber stopper with a hole for an airlock for safely sealing demijohns and fermentation vessels. Thanks to its soft and flexible material, it inserts easily and provides a tight seal during fermentation. The airlock hole allows gases to escape without the risk of contamination and it does not react with the contents, so it does not affect the drink’s taste or aroma.
A rubber cork with a precisely drilled hole is an ideal choice for home production of wine, beer, and other fermented beverages. It provides a reliable, tight closure for demijohns and other fermenters while enabling controlled CO₂ release via an airlock.
Thanks to its inert material, it does not absorb odors or flavors and does not affect the final beverage. It is designed to fit standard neck sizes and, thanks to its durability, is suitable for repeated use, making it an economical and sustainable solution for any home winemaker or brewer.
