The air bung is a crucial component of any home brewing setup. This small but essential item helps regulate air pressure in your fermenting vessel, ensuring that your brew ferments correctly and prevents unwanted bacteria or other contaminants from entering.

Made of high-quality, food-grade materials, the air bung is designed to fit snugly into your fermenting vessel's airlock. It creates a tight seal, preventing air from entering the vessel, while allowing the release of carbon dioxide produced by the yeast during fermentation.
