Is the Fermentation Kit for Wide Mouth Mason worth it?
A top pick in Home Brewing & Wine Making on Amazon (#5 when we checked, Oct 13, 2026)
Worth it if This is worth it if you want a ready-to-use setup for small-batch kimchi, sauerkraut, or other vegetable ferments in standard 86mm wide-mouth mason jars. The glass weights, airlocks, stainless steel lids, and tong give you the key pieces in one kit.
Good to know: If you use regular-mouth jars or want jars included, look for a kit matched to that opening and supplied with containers.
A wide-mouth fermentation kit that keeps vegetables under brine
The Fermentation Kit for Wide Mouth Mason is built around one practical choice: a glass weight that sits on the vegetables. The listing says these heavy, lead-free weights help keep produce fully submerged under brine. That gives the ferment a clearer, more organized setup, especially when you are working with kimchi, sauerkraut, or another small batch.
The lid and airlock handle the next daily annoyance. The stainless steel lid includes a built-in airlock that lets CO₂ escape while limiting outside air exposure, so you do not need to burp the jar each day. Less checking means the jar can stay on the counter while you get on with dinner, work, or the washing up.
The 316 stainless steel lids are listed for acidic ferments and repeated fermentation cycles, with resistance to corrosion and odors claimed by the maker. The kit also includes silicone rings, grommets, a tong, and the glass weights, so the setup is more than a lid alone. The sink is where this either works or doesn't, and having the tong included gives you a direct way to handle the weights. Just match it with standard 86mm wide-mouth jars, since jars are not included.
You get the main pieces for a repeatable small-batch setup in one package: lids, airlocks, glass weights, seals, grommets, and a tong. That can replace assembling each part separately, provided you already have compatible jars.
Great for
- Home cooks making kimchi or sauerkraut in small batches
- Anyone with standard 86mm wide-mouth mason jars
- Fermenters who want glass weights and airlocks together
- People who prefer not to burp jars every day
Maybe not for you if
- You need regular-mouth jar compatibility
- You want jars included in the package
- You prefer a setup without an airlock
The counter case is straightforward: this kit gives wide-mouth jar fermenters the parts they need to start making kimchi, sauerkraut, and other vegetable ferments in an orderly way. The glass weights keep vegetables under brine, while the airlocks let CO₂ escape without daily burping. The 316 stainless steel lids are suited to acidic ferments according to the listing, and the included accessories make the set ready for repeat batches. Choose it if you own standard 86mm wide-mouth jars and want a compact, hands-off setup for small-batch fermentation.
