2.3 / 5.015 ReviewsNot an upgradei have five big mouth bubblers, and was excited to get these when they came out. Unfortunately, they were quite the disappointment as they would not stay in the opening (kept sliding up). I would not recommend this product.February 4, 2016Response from Midwest SuppliesHi Kyle,
Thanks for filling out the review. I'm sorry that the universal lids are giving you trouble. One thing to keep in mind is that they will seal much better if the mouth of the bubbler is dry when the lids are inserted. If you'd like to contact us though, we'd be happy to work on a resolution for you.November 2, 2016Midwest Supplies MThird try and it still isn't rightI think this is the third lid they have made for the Big Mouth Bubbler and again, its a failure in my opinion. I just bought the Universal lid listed here and have the screw on lid before this one. Both of them have been problematic. This one is very flimsy plastic with some nice silicone to attempt at creating a seal. You have to push down on it to try and get it seated and then it shifts back out slightly when you let go. If your airlock is on already, expect a lot of bubbles to go out as you push down and then a significant amount of vacuum and sucking airlock liquid back down into your wort since the lid will not stay in place after pushing it down. It is VERY frustrating and another cheap/poor design. I absolutely love the concept of the big mouth carboy and would gladly pay 2-3 times the price of a high quality lid that works. Instead they seem to crank out different lids like they are disposables. Perhaps they just want you to buy one lousy lid after another in hopes that one will finally work.March 22, 2016Response from Midwest SuppliesThanks for sending the review - sorry to hear the lid is not working great for you. I could probably at the very least credit or refund you for it. You know, you can take the gasket off and put it right on the glass, it has a wider diameter so wont fall in....easily...and then the screw down lid will give a better seal. Some ahve played around with editing the screw down lid to go around the new lid to hold it in place if yours wants to pop up. Inserting dry can also avoid any movement like that. We'll keep looking into solutions for the perfect lid. Let me know how I can help you! Cheers! James J.November 2, 2016Midwest Supplies MSolved the issue!This solved my issue with trying to seal the big mouth fermentors! If you have issues with them popping off under mass pressure, you can trim the new lid and allow for use with the original plastic screw top. Again - this was a huge improvement over the original top!!August 16, 2016I was pleased with theI was pleased with the screw top and ease of cleaning but was surprised that the plastic was so thin.February 15, 2016Finally a lid that sealsOnly used it once, but it finally seals. Well worth it.December 23, 2015Not sure yet...JURY IS STILL OUT ON THIS NEW ONE. BOUGHT IT TO REPLACE THE OLDER GREY THREADED LID WHICH JUST WOULD NOT SEAL.
AT FIRST THE NEW LID JUST WOULD NOT SEAL/STAY IN THE CARBOY. JAMES AT MIDWEST HAD ME CLEAN AND DRY THE LID AND TRY AGAIN. IT WORKED BETTER BUT STILL HAD TO PLACE WEIGHTS ON THE TOP TO GET IT TO STAY SEATED. INVESTED QUITE A BIT IN THE BMB AND THE LIDS SO I'M GOING TO GIVE IT ANOTHER TRY.November 24, 2016Purchased
2 months agoI want a heavy duty versionThe Big Mouth is a great idea, and the new lid makes it clear the makers seek improvement. A plastic swing-top lid would be worth trying.June 25, 2016Leak lidI had to tape down the lid to get it to seal. The previous threaded version sealed better.March 19, 2016Response from Midwest SuppliesHi Mike,
Thanks for filling out a review. I'm sorry your lid was giving you difficulties. One thing that can improve its performance is ensuring that the interior of the bubbler's mouth is dry when the lid is inserted. This allows for a stronger seal. However, if you still experience problems, please contact us and we'll be happy to work on a resolution for you.November 2, 2016Midwest Supplies Mlid leaked from the startPurchased to ferment 4-5 gal batches of wine - made a gasket to fit under the disk - partially solved the problem - still leaks occasionally - bought a universal lid - seems to be working so far (first batch) - have read that the BMB lids pretty much all leak - should start offering the universal lids as replacements...January 19, 2016Big mouth bubbler universal lidI was so excited to try the new universal lid, but they don't seem to stay down. I'm not sure what is wrong but even with nothing in the fermenter they slowly work themselves out.February 16, 2016Response from Midwest SuppliesHi Charles,
Thanks for submitting your review. I apologize for the difficulty you're having with the new lids. Often, this issue can be resolved by ensuring that the interior of the bubbler is dry when the lid is inserted. Otherwise, the lid can be strapped down or taped to keep it down. If you suspect a faulty gasket, we are more than happy to replace it as well. If you would like to pursue this, please contact us directly and we would be happy to work on a resolution for you.November 2, 2016Midwest Supplies M

Browse 2 questions Browse 2 questions and 2 answersThis lid is trash. Doesn't seat correctly, and pushes up even when the carboy is completely empty. I had to tape it down to use it. Original design was superior. They need to redesign, and reimburse everyone they ripped off. Question is: Am I still a virgin after getting raped by these cats? I sure feel shafted.BEST ANSWER: Greeting,
Thanks for contacting us. I'm sorry that you're having difficulty with the new lids. We created them in response to the poor seal of many of the older lids. The new lids generally seal very well if the fermentor's mouth is dry when the lid is inserted. However, if you're unsatisfied with their performance, we would be happy to work on a resolution for you. To do this, please send us a separate email to email@example.com
Thank youI can not get the lid to sit properly to create a good airlock, it keep pushing out even when the BMB is empty. The ribbed collar keeps bunching up instead of going into the BMB, which causes the whole kid to push its way back out.
I have seen other models with a screw on top, am I just missing that piece? There are threads on my BMB, so wasn't sure if that was it, I have a bad collar, or I just don't know how to use it.
Was really excited to use this, but had to transfer my brew into another Carboy because I didn't trust it. Very disappointed, and hoping this can still work.BEST ANSWER: The BMB originally came with a screw top, but that didn't form a seal at all. The universal lid does work for me. You can't add the screw top with the universal lid. Try removing the silicon seal and re-seating it. I have not had the issue that you described.
