These glass airlocks can be used instead of the common plastic airlocks. They are more expensive but if you're careful they will last a lifetime.

Great for making homebrew beers and spirits and they can also be used with to make fermented foods such as

  • Kimchi
  • Kefir
  • Kombucha
  • Sauerkraut
  • Tempeh

Fits standard airlock grommets

The second image is for reference only. It is showing how an airlock is used in the top of your fermenting jar while you're making your healthy, stomach and detox friendly fermented foods (glass jar and lids sold separately).


Materials and Environment:
Made from hand blown glass.

End of life:
If damaged, the glass can be put into your recycling bin with your other glass waste.

Whats great about this product:
Sometimes the "old ways" are the best ways. Almost every airlock is now is made with plastic. Sure it is easy, cheap and light but unfortunately we are not good at recycling it, usually it is just "down-cycled". This is just a simple old time product which can last a lifetime.
