If you love making your own healthy fermented foods, you'll love our glass fermentation jars. These high-quality glass jars come with airlock lids that allow gas to escape while keeping contaminants out. Use to make sauerkraut, kimchi, pickles, kombucha and more. 

What to consider in choosing a Fermentation Jar

Glass jars are a simple and effective way to ferment vegetables at home. Whether you're using a dedicated fermentation jar, a traditional crock, or a clean glass bowl, the key to successful fermentation lies in how you manage gas release and prevent oxygen exposure.

Standard screw-on or clip-top lids:  *Important* Fit lids loosely to allow gases to escape, but this also lets air in, which can increase the risk of mould. If sealed too tightly, pressure can build and cause leaking or the jar to break. We do not recommend standard metal mason jar lids as the salt can cause the metal to rust, which may contaminate your ferment over time.

Specialty fermentation lids: These include airlocks, one-way valves, or silicone gaskets that allow carbon dioxide to escape while keeping oxygen out. This creates a safe, anaerobic environment and greatly reduces the risk of mould.  Fermentation jars with airlock lids are ideal for both beginners and experienced fermenters.

Cloth covers: Using breathable fabric such as muslin, cheesecloth, or a clean tea towel secured with a rubber band is a traditional method that allows airflow and gas release. However, it offers less protection from contamination and is best suited to dry-salted ferments with minimal liquid.

Whatever fermentation vessel and lid you choose, always wash all jars and utensils thoroughly in hot, soapy water before use. A clean start gives your beneficial microbes the best chance to thrive.
