High-quality rubber stopper for 54 L glass demijohns ensures a tight and secure seal during wine or beer fermentation. Thanks to its conical shape and flexible, chemically inert material, it does not affect the taste or aroma of the beverage. The integrated hole for an airlock allows gas to escape while preventing contaminants from entering.
This rubber cork is designed for 54-liter glass carboys and is ideal for home winemakers and brewers. The conical shape ensures a firm fit in the demijohn neck, while the chemically inert rubber guarantees no impact on the aroma or taste of the fermenting beverage.
