The airlock system is used to prevent beer or wine contamination by allowing carbon dioxide gas (produced during fermentation) to escape from the barrel but preventing oxygen from entering the barrel. Half-fill the airlock with water or a sulphite solution when fitted to the barrel. The 3 piece design is great for easy cleaning. This fits the 10 liter size barrels only and cannot be used on the smaller barrels.
