Product Specifications Product Name: Wide Mouth Stainless Steel Fermentation Kit (4-Pack) Material Composition: Non-Porous High-Density Crystal Glass, Food-Grade 304 Stainless Steel, BPA-Free Plastic, Food-Safe High-Elasticity Silicone Lid Compatibility Matrix: Standard Wide-Mouth Thread Grids (3.46 in Diameter) Single Glass Weight Mass: Approx. 7 oz (200 g per unit — Heavy-Duty Industry Standard) Application Scenarios: Probiotic Kimchi Prep, German Sauerkraut Crafting, Traditional Drip Pickles, Brine Fermented Vegetables Why Choose Us? (The Heavy-Duty Advantage) Most ordinary plastic shields or lightweight glass pucks on the market fail because they lack the physical weight required to hold expanding vegetables down. During active brewing, the massive carbon dioxide gas bubbles will lift lightweight weights up, causing ingredients to float, expose to oxygen, and rot completely. Our kit features ultra-thickened, solid 7 oz (200g) high-density glass fermentation weights. Only when a weight is heavy enough can it generate a relentless downwards force matrix to lock food securely beneath the protective brine line, ensuring zero air contact and a 100% fermentation success rate! Step-by-Step User Manual Pack & Weigh Down: Pack your prepared vegetables and salt brine neatly inside your wide mouth mason jar. Next, place our exclusive heavy-duty 7 oz glass fermentation weight right on top. The massive gravity profile will keep ingredients fully submerged under the brine line, completely removing exposure to remaining air corridors to avoid food spoilage. Insert Gasket & Seal Lid: Place the food-grade silicone sealing gasket flatly inside the 304 stainless steel lid rim. Screw the metal lid tightly onto your glass jar to ensure an exceptional, airtight lock with zero risk of leaks. Open Stopper & Insert Airlock: Pop open the small white silicone sealing stopper located directly in the center pre-drilled hole of the stainless steel lid. Push the bottom stem of the automatic one-way airlock firmly into this open hole. Add Water & Auto-Exhaust: Pour a small amount of clean water inside the plastic airlock chamber (up to the calibrated fill line). This advanced dual-channel automatic exhaust system creates a flawless hydraulic barrier that vents expanding carbon dioxide seamlessly while dead-locking external oxygen out, effectively preventing jar-bursting hazards or fermentation failure. Finish & Airtight Storage: Once your pickles have reached optimal flavor profiling, simply lift the plastic airlock away from the lid. Quickly press the center silicone stopper back down to seal the hole. Your batch is instantly sealed for cold fridge storage with zero jar swapping required! Please Note 1.
