About This

• The Mason Jar fermentation kit includes 4 anhydrous fermentation caps that do not contain bisphenol A. Four colors make your kitchen rich and colorful. Suitable for 86mm wide mouthed Mason bottles.
• These ferment caps have a one way waterless valve to vent ,that automatically vents vegetables as they ferment, and this simple one-piece airlock eliminates the need for water, manual burping and maintenance, it also reduces the risk of dust ingress.
• Food produces a large amount of gas during the fermentation process, which can be discharged from the top of the lid without external air entering the interior. This ensures that the food will not spoil. Made of high-quality silicone, with a long service life.
• If the gas inside the bottle cannot be discharged, it will cause the lid to fall off or the bottle to easily burst and deteriorate. That's why our self exhaust valve can prevent danger and food spoilage from occurring.
• Let's take our children to make sauerkraut on the weekend. Radish and cucumber, carrots, and long beans not only enrich our daily life, but also add delicious vegetables to our families and probiotics to our intestines.
