5Pack Fermentation Airlock,Twin Bubble Fermenting Improved High Transparency S Shape with 10pcs Grommets Drilled 3/8’’ Hole

A Must Have for Home Brewing Work Great for Fermenting Vegetables When an airlock bubbles, it simply means that the air pressure inside the bucket or carboy is sufficiently high to push up the little column of water and relieve the pressure.If it fails to bubble, all it means is that the pressure within the fermenter isn’t high enough to make it do so.

This can easily happen if the lid isn’t fully closed, or if the seal isn’t perfect.

For those of you not very familiar with Airlocks, this is a device that is needed when brewing things like beer, wine, meads, etc.You just fill with 1/2 or 1/3 water, pop on the cap, and plug it into your fermentation vessel.The airlock will allow the gas from the fermentation to escape while keep air and contaminants out.

An airlock just *feels* more professional, and is reusable, and is far less susceptible to clogging.
