Fermentation lids for mason jars

[Essen1]

I thought these might come in handy for sourdough starters, sponges and poolishes and preferments...eliminates the need to degas the jars due to pressure build-up, and also eliminates the risk of mold for other fermented foods, such as Kimchi or Sauerkraut.

Couldn't you just use a regular lid and only tighten it slightly, like when you put it into a hot water bath for canning?

Wouldn't that still let air in? I think these lids prevent that.

Thats what I have been doing for over a year.

I prefer using Fido/le parfait/kilner style jars with the volcanic rubber seals and spring bails (I know my terminology is a bit off). They actually do exactly this naturally (off-gas, while being a one-way valve). And I use them for my ferments and my starter. They work amazing!

Of course if someone has tons of mason jars and isn’t looking to change their whole system.....

Mike,

I use a similar top (Masontops) for lactofermenting pickles, cabbage, and other vegetables. Too often, mold forms which I assume means oxygen is getting in. Probably not an issue with starters, but I no longer use these for pickling.

After trying several different jars for starter I have settled Weck jars. straight sides make them easy to use. Just remove the rubber and clamps. Glass tops sit nicely.

Bill,

Thanks for the info. Like you said, for starters and such they may be fine. I think I'm going to order a set and see how they work with a poolishes.

There you go...that might even be a better solution.

I should try an airlock on my levain jar

My brother has been using tops like these for years for pickling!

I just use a plain old 1 qt cambro with hard plastic snap on lid.  Working well for years now.  Learned it from a commercial guy that used a one gallon cambro with same hard plastic lid.  These are the lids that snap on, but don't have an airtight seal.

Hans,

I'm surprised the lid wasn't blown off.
