Glass Fermentation Jars with Airlock & Weights

Make homemade fermentation easier, cleaner and more reliable with these glass fermentation jars, designed for kimchi, sauerkraut, pickles, gherkins, yoghurt, natto and everyday kitchen storage. Each jar features an automatic one-way airlock that allows fermentation gas to escape naturally while helping to stop outside air from entering. This reduces the need for manual burping and helps prevent pressure build-up during the fermentation process.

The thick high-borosilicate glass body is lead-free, odour-free and suitable for repeated use. It is resistant to heat, acid and alkali, making it ideal for fermenting vegetables and storing sauces, dry goods or other kitchen essentials. The clear glass design lets you monitor colour, bubbles and fermentation progress at a glance without opening the jar, helping you keep better control of the flavour and texture.

The airtight clip-lock lid is fitted with a food-grade silicone seal ring to help reduce leaks, spills, dust and unwanted contamination. A stainless steel clip keeps the lid firmly closed for more stable fermentation. Each jar also comes with a glass weight that helps keep ingredients fully submerged under the brine, reducing floating vegetables and helping to prevent mould.

With a wide-mouth opening, the jar is easy to fill, empty and clean after use. It is a practical choice for beginners and experienced home fermenters alike, offering a reusable, space-friendly and versatile solution for healthier homemade fermented foods.
