Home Fermentation Kit With 4 Wide Mouth Fermenting Lids With Airlocks, Oxygen Extraction Pump, Ideal For Sauerkraut, Kimchi, Pickles & Fermented Vegetable

This product is absolutely amazing! It was my first time fermenting, and I was concerned about safety, mold, and harmful bacteria. However, if you follow the instructions, there is nothing to worry about. The oxygen-removing feature is a game changer. It made the entire fermentation process simple and worry-free. I just opened my first jar after 14 days, and the sauerkraut turned out amazing. I highly recommend this product to anyone who is new to fermenting or wants a safer, easier way to get great results.

For many years, I have been fermenting my home-grown peppers to make hot sauce, doing so anaerobically and 4 to 6 mason jars at a time. The bubbler kind have never failed me but do require more head space than my storage closet provides. Used the flat rubber kind that have a little nipple in the middle for for a couple of years. But, every now and then, one would fail, allowing in oxygen with resultant growth of a contaminating bread mold. I have now used this product for two years and have never had a failure. I also like the exhaust feature. The little pump allows me to remove most of the air when I first start the fermentation process. After 3 or 4 weeks of fermentation, they can be exceedingly hard to unscrew. Several times, I have had to use my very largest pipe wrench and all my oomph to open one. Not sure why. I always wipe the jar rim clean before screwing them on. Guess I will have to start apply a little food-grade lubricant to the threads and gasket before sealing.

This worked great - is exactly what I needed.

Purchased this set because it included a pump. Fermentation lids and pump function very well. Happy with this purchase.

Wish I'd had these from the beginning of learning to ferment foods! What an improvement over other lids. I used these immediately to ferment garlic that I keep in the fridge all the time for easy use in recipes. Was very pleased with the results and ease of use, plus the little pump that comes with the kit is great. These lids seal snugly yet are easy to remove. Highly recommend.

These are fabulous no mold no normal fermentation karma yeast even. Checked ph at the end, perfect. No burping and no sputz on the tops. They are well worth the money. Using the pump to illuminate most of the air takes all the concerns out of the picture. Definitely fits my wide mouth Ball jars, pints and quarts.

Easy to use. Clean. Strong. Have not lost a single ferment since I began using these lids to remove air. With all the work that goes into growing and processing vegetables, that's worth the price right there.

These are fine, but the one-piece setup means that as soon as the pump breaks down, and as cheaply as it's made it's going to break, then your fermenter lids are virtually useless. Yes, you don't need to vacuum to ferment, but it's much safer, especially if you want to use a 2% brine. At least with 2-piece lids, you can use a wide mouth mason jar adapter to create a vacuum. The main issue is that when the vacuum pump breaks, there's no way to get a replacement, you have to buy the whole kit again (I know, I asked). The lids seem sturdy and well made, but that pump is flimsy and cheap with zero consideration for the user.

Tras abrir la caja, descubrí que la bomba no extrae el aire de los frascos Mason. La bomba no aspira aire. La junta interna no ajusta firmemente contra las paredes del tubo; existe un espacio visible entre ambas. Considero que este producto ha sido fabricado con un control de calidad deficiente o inexistente.

Very good but give it a 4 because it's very expensive here on Amazon in Sweden.

These work flawlessly. Very happy with my purchase. No I can do long ferments and not worry about any nasty mold

Works well and keeps contents from molding so far very happy.

These are great. A must have if you like to ferment veggies.
