This fermentation setup centers on a wide mouth glass jar designed for home fermentation projects. The opening measures 4.3 in. in diameter, enabling easy transfer of ingredients, scooping with cups, and thorough mixing by hand. The jar stands about 10 in. tall and roughly 6.2 in. across, offering a compact footprint that fits on kitchen shelves and in cool storage spaces. A dedicated airlock lid system fits securely with a food grade plastic construction, and includes a built in silicone gasket for a tight seal, plus silicone grommets to seal the airlock hole without transferring contents. The kit comes with three airlocks and a spare, supporting multiple batches without dismantling the setup. The jars are made from thick glass designed for repeated use, and are easy to clean, including dishwasher compatibility. Clear scale marks in both milliliters and fluid ounces help with measuring fermentation volumes without separate tools. Additional components include square mason jars with compatible lids, spare grommets, and writing boards with a pen to label batches. Together these parts provide a practical framework for fermenting fruits, vegetables, starters, and beverages, with attention to durability, ease of use, and minimal disruption during ongoing projects. The setup is compatible with a range of recipes and scales. Size: large.
