Airlock Bubblers

Our Price: £0.80

6 chamber airlocks or bubblers fitted with dust cap

Airlocks need to be securely fitted into a bored bung or grommet in a demi john to release CO2

Fill the airlock 1/3 up with water, fit into bung and as your brew ferments the water in the airlock will bubble indicating that CO2 is being released and your brew is fermenting

The water in the airlock can bubble quite vigorously at the beginning of fermentation, slowing down as your wine or beer ferments
