Product: Hands down one of the best things you can own if you are fermenting anything of any nature, and our most recommended and popular product! We have created this lid set to help improve your ferments, without breaking the bank (no costly jars, shipping, etc!). Simply add this lid system to any mason jar you already have and experience the wonderful results of an air lock!
Why an airlock? When fermenting symbiotic cultures the benefits of a cloth lid usually outweigh those of a closed lid. But with an air lock you have the best of both worlds.
It allows built up gas pressure to escape
Remains more clean and 'pure' (in strains)
Keeps the outside air (foreign yeasts, bacteria, and bugs) out
