Hersolm Fermentation Kit 4-Pack for 3.3" Wide-Mouth Mason Jars — Glass Weights & Rustproof Airlock Lids

Hersolm's 4-pack fermentation kit supplies four glass weights, four wide-mouth airtight lids with silicone gaskets, and four water airlocks designed for 3.3" wide-mouth mason jars (jars not included).

Whether you're new to lacto-fermentation or expanding your at-home setup, this compact kit gives you the essential hardware to ferment small batches of sauerkraut, kimchi, pickles and other vegetables. The kit focuses on an easy airlock system, rustproof screw lids with date trackers, and ergonomic glass weights that keep ingredients submerged for consistent, reliable results.

How does this kit keep vegetables submerged and safe during fermentation?

The included glass weights have an improved 1-inch knob handle so you can place and remove them cleanly without touching the brine. Submerging vegetables prevents mold and promotes the right environment for lactic-acid fermentation.

• Four 6.5 oz (≈185 g) tempered glass weights with ergonomic knob handles for easy removal.
• Weights fit common 3.3" wide-mouth jars and sit flat on packed vegetables to maintain brine coverage.
• Glass material is non-reactive and simple to sanitize between batches.

What makes the lids and airlocks effective for fermenting at home?

Hersolm's lids combine a one-way water airlock with a silicone gasket to release CO2 while blocking oxygen. The screw lids are rustproof and include a date tracker to help you manage fermentation timelines for multiple jars or staggered batches.

• Four wide-mouth screw lids sized for 3.3–3.4" openings, engineered to resist rust.
• Food-grade silicone gaskets for a snug, reusable seal and reduced contamination risk.
• One-way water airlocks: fill halfway with clean water to allow gas escape while preventing air ingress.

How easy is setup, cleaning, and reusing the kit?

Setup is straightforward: pack vegetables, add brine, position a glass weight, fasten the lid, and fill the airlock partway with water. After fermentation, remove the silicone plug, wash components, and reuse them for new batches—no complicated tools needed.

• Simple step-by-step process suitable for beginners: pack, weigh, seal, monitor.
• Components are dishwasher-safe or hand-washable; glass and silicone are durable for repeated use.
• Date tracker on each lid helps you rotate and plan batches efficiently.

Who is this for? Home fermenters who use wide-mouth mason jars and want a compact, reusable kit to run multiple small batches at once will find this Hersolm set handy. It’s ideal for people experimenting with sauerkraut, kimchi, pickles, and other vegetable ferments who prefer glass contact surfaces and an airlock method that reduces oxygen exposure. Bakers, home-canning hobbyists, and anyone wanting an organized, rust-resistant fermentation workflow will benefit from the four-lid, four-weight, four-airlock configuration.
