Simply Sauer Fermentation Airlock Bundle Kit - Fits Wide Mouth Mason Jars - Supplies Include Airlocks, Pump

I have many fermenting vessels and tools but this one is fool-proof, use these along with the Simply Sauer glass weights and you can't go wrong. I pull a slight vacuum at the beginning to remove oxygen, then when the ferment activity is done I use the vacuum again to keep out the nasties. It's perfect for removing some cabbage etc. for a taste and then pulling a vacuum which will remove the oxygen since there is no longer Co2 production to push the oxygen out again. Will definitely buy some more of these and the glass weights. I also like the ability to see through the top, which gives these a great advantage over similar vacuum tops.

These fermentation lids are literally awesome!!! Screw onto wide mouth lids with ease and are made of quality plastic, they are extremely durable and well made. Was unsurr about the pump but after watching my saurkraut, i see how incredibly useful the pump is to remove the excess gas by removing it. I can forsee they shall last a long time thru many many batches of fermentations. I Def recommend these to anyone looking for a quality product that surpassed my expectations. Thank you for an excellent product. Will most def purchase more. Haven't found any that I can just purchase without the pump....Def don't need an excess of pumps with every 4 lids bought. Just a thought!!!

There are no options to buy additional lids without another pump. Very stupid. The lids themselves are solid, though the plastic hook is a little weak.

These are simple to use and work great! The reason for only 4 stars is that one of them does not work when using the pump to get the air out! But that said Excellent product! Been fermenting for years and really am enjoying the "easy"!!

Basically a 'set it and forget it' item. You screw it on the wide mouth jar, evacuate the oxygen using the small, manual evacuation pump that's included in the package - and that's IT! You no longer HAVE to worry and wonder if you've 'burped' your jars, that day, it's done automatically. Want to test your product to see if it's done. Do it! Then go through the steps again securing the top and evacuating the air that was introduced. It couldn't be better, fulfilling every need.

Delivery was confirmed. However I never saw the product. I've been too busy to confront Amazon or its delivery. I mean, they have pictures. Of what? I don't know. I've got a dozen or so similar caps and they are marvellous. Simplifies and improves the whole fermenting process.

All vacuum lids are not the same. The fact that you can see through these is really, really convenient for checking on the progress and cleanliness of your ferment. Other vacuum lids exist but every single one of them seems to be opaque meaning that you have to side-eye the top of the brine to see how its doing. Or worse, you have to remove the lid to even check. I only wish they sold these in an 8 or 12 pack without the pump. I already have enough of their pumps now! :)

FYI, be careful when putting the lid on to make sure it is on flat and threaded correctly, but otherwise they work great. Having headspace is important with these as you are going to pump out air and this will cause bubbling. I am using them right now to make fermented pepper hot sauce and they have been much easier than using a traditional crock.

ok

Come prodotto è davvero ottimo e mantiene la pressione, se maneggiati con cura durano a lungo.

I've had a set for a few years and used them in making Kefir. They work very well and the tops are still perfect. Now this new set will be to ferment vegetables. So, having purchased these for the 2nd time speaks for itself. They are simple, durable, effective and a great value.

These are great. The lids screw on hand tight, the air is pumped out and a negative pressure is maintained by the seal in the lid until CO2 replaces the partial vacuum. Brilliant. Buy once with the pump and any other purchases can be just the lids which are around a fiver cheaper.

Using these in combination with Ball Jars has been the best solution for home fermenting I have found. Super simple and clean and effective.
