2, 32 oz. glass fermentation jars form the core of this kit, paired with weight disks, 2 wide-mouth stainless steel lids, 2 airlocks, 2 silicone gaskets, and 4 silicone grommets. The jars are thick glass with balanced weight, designed to support steady fermentation. The airlocks are made from food-grade PC material and are compatible with the included lids. Filling the jars and setting up is straightforward: insert a fermentation weight to keep solids submerged, secure the lid with the seal, and place the airlock in the lid. When ready to store or pause fermentation, the airlock can be removed and a silicone plug seals the jar to preserve your fermented foods. The airlocks operate by releasing gas through water, reducing the risk of overpressure and minimizing exposure to air, which helps maintain a clean fermentation environment. The kit is suitable for making kimchi, sauerkraut, pickles and similar fermented vegetables, offering a simple, reusable setup that supports both beginners and experienced fermenters. All components wipe clean and can be reused for future batches, making it a practical option for home fermentation projects. The included hardware is designed for easy disassembly and cleaning, and the containers resist staining from spices and vegetables over time.
