About this product
The Almost Off Grid Fermentation Airlock & Bored Cork Demijohn Bung is a vital accessory for any home fermenter looking to create delicious beer, wine, or kombucha. This essential component ensures your fermentation process runs smoothly and efficiently, preventing unwanted airborne contaminants from spoiling your brew while allowing the natural carbon dioxide produced by yeast to escape.
Designed with practicality in mind, this airlock fits standard-sized demijohns – a common vessel for home brewing – and boasts a top diameter of 32mm and a base diameter of 28mm, ensuring a snug and secure fit. Crafted from durable glass and featuring a robust cork bung, it’s built to withstand the rigours of fermentation. The cork bung is designed to fit standard glass demijohns and is a budget-friendly addition to any fermentation setup.
This airlock effectively seals your fermenter, allowing CO2 to escape without letting in oxygen or bacteria – the two biggest enemies of successful fermentation. While a fantastic value for money, it’s worth noting that the cork bung can occasionally dry out over time, requiring replacement to maintain optimal performance.
