Airlock Homebrew Bubbler and Gromit
€1,85
Keep your fermentation safe, clean, and contamination-free with this classic bubbler-style airlock, designed for wine, beer, cider, and mead brewing. Simple, reliable, and easy to use—an essential tool for every homebrewer.
Fitted to a fermenter lid or demijohn using a bung (sold separately), this bubbler airlock holds a small amount of water in its U-shaped chamber. As fermentation builds CO₂ pressure, the gas escapes through the airlock while preventing oxygen from entering the vessel.
This one-way system protects your brew against:
- Oxidation
- Airborne bacteria
- Fruit flies and insects
- Dust and debris
Features:
- Includes a protective plastic cap to block dust and insects
- Clear plastic body for easy monitoring
- Prevents oxidation during long fermentations
- Fits all standard bungs and fermenter lids with an airlock hole
- Reusable and easy to clean
Brewing Tip:
Do not overfill the airlock—too much water can be sucked back into your fermenter during temperature changes or pressure drops. A small amount is enough to create a safe barrier.
Perfect For
- Winemaking
- Beer brewing
- Cider and mead fermentations
- Kombucha and experimental ferments
