Designed for home fermentation, this kit provides a complete set of components to support pickling, kraut making, and other small batch projects. It includes 4 glass weights to keep produce fully submerged in brine, 4 wide mouth lids made from stainless steel with food grade silicone gaskets, 4 BPA free water airlocks, plus 5 silicone stoppers and an extra silicone gasket for storage. The weights are high density glass and weigh about 7 oz. (200g) each, promoting steady submersion without attracting odors or flavors from the brine over time. The stainless steel lids resist rust and form a tight seal with the silicone gaskets, while the wide mouth design allows easy filling, checking, and cleaning. The airlocks are designed to release CO2 and prevent backflow, with pre drilled holes and reinforced grommets to maintain reliable seals during fermentation. When fermentation completes, the silicone stoppers let you plug the lid holes to switch to storage mode without replacing lids, simplifying post fermentation handling. This kit is compatible with standard wide mouth mason jars, offering a compact and clean setup for sauerkraut, pickles, kimchi, and other homemade ferments. Note that jars are not included but the kit provides the essential components needed to create a stable fermentation environment at home.
