Description

What is an airlock for fermentation?

Mason jar airlock? What is that? An airlock is used to create an anaerobic (without air) fermentation environment for your vegetables.

Why do you need an airlock for fermenting vegetables?

An airlock ensures that carbon dioxide can escape, but that no oxygen, fungi or fruit flies can get to your fermenting vegetables. The carbon dioxide that is naturally created by the lactic acid bacteria is heavier than air and will stay inside of your fermentation vessel as a protective anaerobic ‘blanket’.

Advantages of using an airlock when fermenting vegetables

  • Preventing air from entering your jar
  • No need to ‘burp’
  • No maintenance
  • Preventing mold spores and yeasts from entering your jar
  • No chance of exploding jars
