Kilner Fermentation Set

The air lock system is designed to allow gases produced during fermentation to escape while preventing oxygen and contaminants from entering the jar. This creates the anaerobic environment necessary for successful vegetable fermentation without requiring you to manually 'burp' the jar.

While the 5-liter capacity is generous, it is very beginner-friendly. The large size is actually helpful for those just starting out because it allows you to make substantial batches of sauerkraut or kimchi at once, reducing the frequency of prep work.

While the design is optimized for fermentation, you can certainly use the glass vessel for general storage once you remove the air lock. However, the silicone lid is specifically engineered for the fermentation process, so it may not provide the same airtight seal as a dedicated food storage container for long-term pantry use.

The heavy-duty glass is durable, but like all glass fermentation vessels, it should be washed with warm, soapy water and rinsed thoroughly. Avoid using extreme temperature changes, such as pouring boiling water directly into a cold jar, to prevent thermal shock.

This set includes the essential components for the fermentation process, but it does not come with glass weights. Depending on your recipe, you may want to use a ceramic weight or a clean cabbage leaf to keep your vegetables fully submerged beneath the brine.
