This fermentation kit provides all essential components for safe, controlled anaerobic fermentation at home. It includes four glass weights to keep vegetables fully submerged under brine, four 304 stainless steel wide-mouth lids with food-grade silicone gaskets for airtight sealing, and four water airlocks that allow carbon dioxide to escape while preventing oxygen and contaminants from entering. Five additional silicone stoppers and one spare gasket support post-fermentation storage without lid replacement. The glass weights are non-porous and odor-resistant, ideal for repeated use with sauerkraut, kimchi, pickles, or other fermented vegetables. All parts are designed to fit standard wide-mouth mason jars, making setup straightforward and cleaning simple. No jars are included, but compatibility is consistent across common 32-ounce and 64-ounce wide-mouth sizes. Materials meet food-safety standards: borosilicate glass, 304 stainless steel, and FDA-compliant silicone ensure durability and inert performance. The dual-channel airlock design enhances gas release reliability, while the seamless lid construction minimizes crevices where bacteria could accumulate. This system supports both active fermentation and long-term refrigerated storage.
