Size: Stainless Steel Fermenting Lids
My husband has had stomach problems for the last few years. Many doctors, many pills - NO RELIEF. Began reading about how to improve health using Fermented Foods! I doubted it would help but tried it anyway. Within a week my husband began getting better. Every day it seems he is continuing to feel better. We are in our 60's. Have not eaten the healthiest of diets. Eating FERMENTED FOODS IS A GAME CHANGER!!! Stomach pain - GONE! I highly recommend Fermentation!

We love to use these for a quick and easy sourdough bread loaf recipe. Mix it up in 1/2 gal mason jar and pop this lid on. Let ferment for 72 hours, transfer to a loaf pan and bake it. It turns out AMAZING! makes sourdough bread so easy!

Just got these yesterday and got some of my homemade sauerkraut going. I read a bunch of reviews and felt like I should share my initial thoughts. The airlocks are heavy and well made compared to the ones I’ve used in the past. These are fiddly things that no matter how well made are prone to cracking and breaking, especially if you are too rough with the cap. I am, so far impressed with the quality of these air locks. The reason I only give 4 stars is that this is my first time using plastic lids for my ferments and that makes me nervous. I got them because the initial fermentation videos I watched years ago had plastic lids and not the metal lids or the plastic inserts into the ball lid ring. I will revise this when my batch of sauerkraut is done.

These fermentation lids are mostly fine but they don't properly fit on the 64oz Ball jars for some reason. It's like they twist and twist and twist and never secure - so weird. They're still usable on the larger wide mouth jars but they just don't 100% secure when you tighten them. Fits fine on the 32oz, 24oz, and 16oz wide mouth jars. And of course they are not water tight so if you tilt them or overfill them they'll leak from the sides. Plastic sucks but they don't rust out like metal lids when you're fermenting with vinegar or salted brine.

The only thing I was worried about were the posts talking about these lids not fitting my BIG 48 ounce marked jars (64 ounce total capacity). THEY FIT FINE!
