Turn any wide mouth jar into a fermentation powerhouse

Transform ordinary mason jars into a complete fermentation setup with the Jillmo Fermentation Lids. This 6-pack kit is crafted for home projects like sauerkraut, kimchi, and kombucha, offering a practical blend of control, ease, and reliability without locking you into a single jar size.

With every pack you receive a cohesive assembly of lids, grommets, and airlocks designed to work together for steady, flavorful ferments. The design prioritizes ease of use and durable materials, so you can focus on the craft rather than the setup.

What’s included

• 6 wide mouth fermentation lids with seals
• 6 silicone grommets
• 6 BPA-free water airlocks

Key features for dependable fermentation

• Designed to fit jars with a 3.38 inch outer diameter mouth, compatible with small 4 oz to large 64 oz wide mouth jars
• A 14 mm airlock hole allows easy airlock insertion without stressing the silicone grommet
• The airlock system provides venting to release gases while keeping external air out
• Silicone seals and grommets ensure a tight, reusable seal for consistent fermentation conditions
• All components are BPA-free, emphasizing a practical, food-safe home fermentation setup

Usage tips and care

• Do not sterilize the plastic airlocks with boiling water; use warm water instead
• Keep jars in a stable location away from direct heat or sunlight during fermentation
• If any small parts are damaged during delivery, we will replace them within one year

Note that jars are not included with this kit. You can pair these lids with your existing wide mouth jars to start fermentation right away, and the 6-pack gives you flexibility for different batch sizes or concurrent projects.

Ideal for curious home fermenters

The Jillmo lids aim to simplify the process while maintaining control over texture and aroma. The design supports rapid setup, easy airlock insertion, and a dependable seal, making it a practical upgrade for ongoing kitchen projects. While results depend on factors like brine strength and ambient conditions, the kit suggests possibilities for smoother, more predictable ferments when used with compatible jars and recipes.
