The Kilner Fermentation Accessories is specially designed to be used Kilner Preserve Jars. The silicone valve integrated in the fermentation lid will release the gas that builds up inside the jar during the fermenting process but does not allow air to enter. The glass weights have been designed to weigh down the foods inside the jar, keeping it below the water level, preventing the foods from drying out. Perfect for creating smaller batches of live cultures including sauerkraut, kimchi and pickles.
