Simply Sauer Fermentation Starter Kit - Fits Wide Mouth Mason Jars - Supplies Include Weights, Lids, Pump

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

I purchased the Fermetnology kit comprising 2 wide-mouthed Mason jar lids plus an air extracting pump as a present for my husband. The lids were extremely good and all seemed set for our first fermenting experience. However the pump didn't appear a tight enough fit to extract the air, so it appeared to be either dud pump or a design flaw. After contacting, seller who were a delight to deal with, a replacement pump arrived and works a treat! I found the seller to be totally committed to their product and customer satisfaction. I'm extremely impressed. I heartily recommend their product - and also think it's good value for money as it makes fermenting extremely easy. My hubby and I are 2 happy bunnies.

Good equipment. Would have been five stars but the pump doesn't work. I've made kimchi and sauerkraut. Both have been successful.

Was very excited to get this to make sure my ferments don't have air anymore in them. Tried them on my new batch and it seems at least one of them lost pressure within a few minutes and others lost it overnight. Not sure they work very well and the silicone valves in them also seem to move a little too much making it unreliable. Edit: The seller was more than responsive to my issues with the kit I was sent. A replacement was promptly shipped and it seems to be better than the last batch (at least for the two days I have used it) in holding off the vacuum and not losing pressure. Would certainly recommend this not only because it works but also the sellers service and prompt response to my issues.

So easy to use and peace of mind while my goodies are fermenting. Wasn’t sure if they would be worth the outlay but they certainly are as I’m in an old house and had spoilage using the burp method, no more spoilage using these🥳

Uk buyers, these lids do NOT fit onto Kilner jars properly. They can’t screw on enough for the sealing ring to make contact with the jar. You can possibly get over this by finding a thicker sealing ring but I’ve not yet tried. Other wise the product seems very good, may be worth sourcing mason jars to use with it.

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.

I purchased these as the as it states they are made from Glass...These are Not Glass! just plastic, and the box tells a different content, it has 4 lids and a pump, the box says 2 lids, 2 stones and a pump? Haven't used them so no stars, although I had to give 1 to get past this page.

Das perfekte Set, die Deckel passen genau auf die Mason Jar Wide Mouth, die kleine Pumpe arbeitet leicht und schnell, falls es mal nicht sofort klappt, hilft es, die kleinen blauen Ventile einmal aus dem Deckel zu entfernen und unter Wasser gründlich zu reinigen. Auch zum Transport von Smoothies unter Vakuum super geeignet, beim Fermentieren verschwindet das Vakuum nach einiger Zeit durch die entstehenden Gase, es läßt sich aber leicht nach der Kontrolle des Inhaltes auf Geschmack und Konsistenz wieder herstellen. Ich hab schon ein zweites Set gekauft, diesmal nur vier Deckel und Pumpe, da ich Gewichte mit Griffmulden noch besser finde.

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.

ok

I ordered a full kit and one of the glass weights had a problem. I emailed Fermentology and quickly got a response. They very quickly replaced the Kit, although I was just expecting the weight to be replaced, they replaced the whole thing. Then the use. While I was waiting for the weight. I tried out the rest and did two batches of Sauerkraut. One with the Mason tops Pickle pipe and one with Fermentology lid with pump. The one with the Mason tops Pickle pipe, I had to throw out due to mold. The Fermentology lid were it was pumped, once about every two days (from the CO2 build up), came out without a problem and a PH of 3.8.. The Pickle lid Never dropped below 4.5 PH.. I'm very happy with the Style of weight, lid and pump of the Fermentology's kit.
