Wide Mouth Mason Jar Lids for Curing, Harvesting, Fermenting, Canning. Vacuum Sealed Patented Tech that Includes 4 Lids with Extraction Pump By Burp Lids

The Burp Lids Vacuum Extraction System is the most significant innovation for Mason jar enthusiasts I’ve tested in 2026. It replaces the "open-and-hope" method with patented vacuum technology that ensures your harvest stays fresh, potent, and mold-free. Here is the expert breakdown. The Engineering: Patented Oxygen Extraction The genius of the Burp Lids system is the One-Way Valve integrated into a high-quality, wide-mouth lid. The Pump: Unlike traditional fermenting lids that rely on passive pressure, this kit includes a dedicated Extraction Pump. By manually pumping the air out, you create a vacuum seal that actively pulls oxygen away from your contents. In my testing, this significantly reduced the risk of oxidation and "browning" in cured goods. The Seal: The gaskets are medical-grade silicone, providing an airtight fit that holds a vacuum for weeks. This is vital for long-term "curing" where consistency is the key to a premium final product. Performance: Curing vs. Fermenting For Curing: This is a "set-it-and-forget-it" dream. Instead of opening 20 jars every morning, you simply use the pump to refresh the vacuum every few days. It preserves terpene profiles and essential oils by preventing the "gas exchange" that happens with manual burping. For Fermenting: It works perfectly as an airlock. As CO2 builds up during fermentation (like making sauerkraut or pickles), the valve allows the gas to escape without letting oxygen in, virtually eliminating the chance of "Kahm yeast" or surface mold. PROS Drastically Reduces Labor: If you are processing a large harvest, this system saves you hours of manual jar-opening over a month-long cure. Increased Potency & Flavor: By maintaining a stable environment and minimizing oxygen contact, your herbs and fermented foods retain their vibrant colors and complex aromas much better than with standard lids. Universal Wide-Mouth Fit: These fit any standard wide-mouth Mason jar (Ball, Kerr, etc.), allowing you to turn your existing glassware into professional-grade curing chambers. Mold Prevention: The vacuum environment is hostile to aerobic mold and bacteria, providing an extra layer of insurance for your hard work. BPA-Free & Food Safe: The construction is rugged, easy to clean, and designed for years of repeated use. CONS Wide Mouth Only: These will not work on "Regular Mouth" jars. You’ll need to ensure your inventory of glassware matches the lids. The "Pump" Factor: The system relies on the hand pump. If you lose the pump, you lose the primary "vacuum" benefit of the kit (though the lids still act as excellent airlocks). Manual Effort: It is a manual pump, not electric. If you have 50+ jars, your forearms will get a bit of a workout! Overall Input The Burp Lids System is a masterclass in functional utility. It takes the guesswork out of one of the most delicate stages of food and herb preservation. It’s an investment that pays for itself by preventing crop loss and ensuring a higher-quality end product. For the hobbyist gardener or the fermentation enthusiast, this is an "S-Tier" tool. Reviewer Pro-Tip: Don't over-vacuum! Give the pump 3–4 solid pulls until you feel significant resistance. Over-vacuuming can sometimes pull moisture out of your curing herbs, making them too dry. Also, store your jars in a cool, dark place—the vacuum protects against oxygen, but the glass still lets in light, which can degrade your contents over time! Who is this for? Herbalists, home gardeners, "Preppers" interested in long-term food storage, and DIY fermenters who want professional, mold-free results every time.

They are 5 star because I don’t think there is another product that’s this easy to use, but out of the 4 I bought 2 of them lose vacuum after a day or two. Not a huge deal right now, but I wouldn’t necessarily recommend for long term storage. The pump is made of fairly cheap materials, but it works well. I could see these being slightly more expensive and twice as good if the correct materials were used. Either way these seem to be the best product on the market.

Burp Lids $19.99 (after a $10 off coupon): 4 lids and a hand pump AIEVE Lids $14.99 : 6 lids (There is an AIEVE set of 6 lids plus a hand pump and a pounder for $21.99 but I didn’t want the hand pump or pounder.) So I wanted 12 fermentation lids. AIEVE was $29.98 for two packs of 6 lids (= 12 lids). Burp Lids was $59.97 (after $30 off in coupons) for three packs, each with 4 lids and 1 hand pump (= 12 lids and 3 hand pumps). I didn’t care about the hand pumps because I wanted to buy the Burp Lids Automatic Pump $24.99 (after a $5 off coupon). I read some reviews that mentioned the Automatic Pump worked with any brand of fermentation lids). The notches in both brands of lids helped me screw and unscrew the lids much better than regular smooth lids. Two packs of 6 lids from AIEVE and the Burp Lids Automatic Pump came in at $54.97!!! FIVE DOLLARS CHEAPER than three packs of Burp Lids (4 lids 1 hand pump per pack = 12 lids and 3 hand pumps). The packaging/branding of the Burp Lids is really nice. And the black and green colors make the lids look really sleek and shiny BUT apart from the colors, the lids were identical to the AIEVE lids. I took all the Burp Lids out of the packaging along with the pumps and examined them for imperfections since a lot of reviews mention receiving defective lids. All 12 lids were in perfect condition. I tested each one on a Ball brand jar, they all fit well. I also tested the hand pumps, they stink, they are very low quality pumps and not smooth to operate at all, all three pumps had the same problems. It takes at least 3 pulls to get all the air out of a jar. I can’t imagine fiddling with the hand pump through 12 lids. I also tested the Burp Lids Automatic Pump on each lid to make sure everything worked right, and I’m happy to report everything worked fine. Next I took all the AIEVE lids out of their packaging and examined them for imperfections and defects too. All 12 were in perfect working condition. I also tested each lid on a Ball brand jar, using the Burp Lids Automatic Pump with each one. They all worked perfectly. Regarding the Burp Lids Automatic Pump, you can just place it on the top of the jar, push the button, wait for it to turn green, turn it off and take it off of the lid and there is a satisfying pop sound when you take it off proving the seal. But I felt it worked better if I just held the Automatic Pump with a little bit of downward pressure against the lid, it made a better and stronger pop sound. Also you can feel it’s a stronger seal when you take the Pump off the lid. I tried to figure out which brand was better but they are exactly the same. The only difference I could find was the weight of the lids, Burp Lids lids came in at 39.2 grams and AIEVE lids came in at 41.1 grams, I don’t know that the weight difference makes any impact on the quality. If the Burp Lids were cheaper I’d be inclined to buy them, the bright green and shiny black, make them look very pretty and high end. But the price, even with the discount coupon, doesn’t make sense to me. The AIEVE lids aren’t quite as pretty or eye grabbing but they work just as well as the Burp Lids so I’m keeping the AIEVE lids and the Burp Lids Automatic Pump, they are a match made in heaven. I’m giving Burp Lids 4 stars due to the high price and sucky hand pump. I’m giving AIEVE lids 5 stars because they work great and are super affordable. I cannot emphasize enough that no matter which brand of fermentation lid you buy, you should buy the Burp Lids Automatic Pump, the hand pumps are completely worthless and a pain in the neck. See my Burp Lids Automatic Pump review for some videos and extra pics.

Super product! Saves time and super effective! Beats a regular mason jar lid any day! Only thing is check the gasket before use some of them need to be placed in the lid straight before using but after that no problems

I purchased this and returned because manual pump broke , the pump stopped working. I opened it to reveal that o ring inside pump that provides suction came off and bunched up in pump. So i returned product, got a replacement and it worked perfectly for one week then did the same thing. I followed the instructions to a tee , and didn’t over pump either , yet pump still failed. Good concept but didn’t work. Burp inc you are welcome to contact me and make right . Updated: since I last submitted, spoke with burp lids. They made things right and sent me an updated pump, works great as it should. Five stars !!!

Either won't seal or don't keep a seal, is what I've faced with these. These lids can be tricky to get on which can prevent a seal. The rubber burp which helps keep the vacuum tend to be too small or off centered. This allows for leakage. The others took a lot of tries and eventually sealed after some toggling and taking the lid on and off. Eventually all lids failed, but after several attempts I got a few to work properly. In the end, only 2 of mine never held a good seal Update: For best results with these lids. Make sure no debris are in the following places: rim of jar or outter sides of jar, lid's rim seal and lid's inner sides. Put the lid on top of your jar. Rotate counterclockwise until lid falls in place. Turn clockwise until tight and snug Make sure burp is centered and not cramp on any side. Do this before and after you use the pump to extract the air from within the jar.

These lids are the best thing invented, especially with the automatic pump. Man o man!! Can't wait for harvest! *** update *** These lids are not the best thing invented. Very cool idea to help with curing but the lids are very very tight once put on. I didn't tighten them when I filed them, next day the lids need the jaws of life to come off. 🤦🏻‍♂️ have to use crazy strength to get the lids off the jars, I'm going back to regular lids. Sending these back!

The way these “work” is that you are pumping air into a closed system, which increases the air pressure inside the jar, then you open the system to release the air pressure. You aren’t exchanging air, you are diluting old air with fresh air. That is if they even work, and mine did not. There is a hole in the center of the lid with a rubber piece over it. You put the pump on this piece to pump air into the jar. The problem is that the rubber piece doesn’t actually form a seal, so it isn’t a closed system. You’ll pump all day and never exchange any air. The pump does not pull air out of the jar. Also, since it doesn’t actually form a seal, the aroma seeps out of the jar. And the product in the jar dries up. Completely defeating the purpose of using the jars. Waste of money, does not work

Two lids don’t vacuum seal. One lid was missing a valve. Contacted the seller, who did not message back.

I really like this product. It's a bit pricey but once I saw how well it worked and how easy it makes my lacto fermenting I'm a believer. I ordered 16 of them total for wide mouth mason jars to do my preserves for the winter from my garden. LOVE them!

The lids are great and the vacuum seals work as asvertised...but the pump does not. It stopped working after 2 days of use and does no longer suck the air out. No way to spot the error and repair as the pump can't be disassembled. A replacement pump (only the old version availabe) costs a whooping 22 Euros here in Germany... That's crazy for such a cheap piece of plastic. Already spent close to 100 Euros on the 12 lid set. In this price range one would expect quality on all parts... If I cant find a cheap replacement for the pump, I got to write the lids off as a failed investment as their main feature is useless without it...

Product is useless for myself as it is too small to fit over the mouth of my mason jar

worked great, easy to use, no mold or fuzz when canning cabbage.
