Jars are a good alternative to large fermenting crocks if you just want to ferment small quantities of vegetables at a time. All our fermenting jars are made of tempered glass which is thicker than standard glass making it more resilient against breakage.

We recommend using our fermenting jars with airlocks: this allows the gas that builds during fermentation to escape without allow new air to enter the jar which can introduce unwanted mould and bacteria.   Our airlock lids come standard with a plastic fermenting airlock but you can also upgrade to our USA handmade and handblown airlocks or the low profile Sterilock airlocks which allow you to store your fermenting jars with greater ease.
