Meet the Klemon Fermentation Lids Kit, a 6-pack set designed for wide-mouth jars. Crafted with BPA-free plastic lids, food-grade silicone grommets, and 3-piece airlocks, it supports experimenting with sauerkraut, kimchi, pickles, and more.

What’s in the kit

• 6 BPA-free wide-mouth lids with silicone rings
• 6 BPA-free water airlocks
• 9 silicone grommets
• 6 silicone rings
• 1 electronic instruction with recipes

Quality and compatibility

The grommets and silicone rings are food-grade and reusable. The lids fit Ball, Kerr and other branded wide-mouth jars from 4 oz to 64 oz.

Air-Tight and fermentation-friendly

• The silicone rings create an airtight seal on the lid.
• The airlocks vent fermentation gases while keeping oxygen out, helping maintain a conducive environment for your ferments.

Ease of use and maintenance

• Assemble the kit quickly; insert the airlock into the lid, screw onto the jar, and add water to the airlock.
• After use, disassemble the airlock for cleaning. The airlocks can be soaked in diluted bleach; avoid boiling water on plastic airlocks.

Cleanliness and care

All pieces are designed for easy cleaning. The airlock components can be disassembled and cleaned with a small brush, and the kit stores compactly when not in use.

Real-world uses

Imagine crisp sauerkraut, tangy kimchi, and crunchy pickles prepared at home with less guesswork. The kit supports home fermentation projects that prioritize safety and flavor, offering a practical path to flavorful, probiotic-friendly vegetables.

Safety and materials

The kit uses BPA-free plastic for lids and airlocks and food-grade silicone for grommets and rings. These materials are designed for repeated use and are easy to sanitize between batches.

Compatibility and jar range

Works with standard Ball, Kerr and similar wide-mouth jars from 4 oz to 64 oz. Jars are not included in the kit, so you can reuse containers you already own.

What you can ferment

Great for sauerkraut, kimchi, pickles, and other vegetables. You can experiment with herbs, spices, and flavor combos to achieve your preferred profile.

Usage tips

• Keep jars in a cool, shaded place during fermentation.
• Replace water in the airlock if it evaporates.
