DetailsThe most helpful fermentor ever invented just got even better. Less effort. Better, clearer beer. Don’t just cut out the hassle of cleaning, cut out siphoning altogether! Porting this revolutionary fermentor makes transferring as easy as the turn of a valve. No extra equipment, no extra cleaning, just a sanitized fermentor.
The Siphonless Big Mouth Bubbler® isn’t just easier to use. It’s better for your beer. Fight oxidation and contamination by keeping your fermentor closed for transfers. Never open the lid to insert an auto-siphon, just turn a valve and you’re set. Best of all, you’ll have clearer beer. Gently rack liquid from the spout into secondary without disturbing the trub.
Make your brew day easier and your beer better with the siphonless Big Mouth Bubbler®.

3.7 / 5.027 Reviewseasy to useDon't forget to open the top when you open the valve, otherwise it sucks the liquid out of the water lock. The port doesn't leak at all, but I would worry about contamination of the valve after a long time in storage. I bought it so my cider would be exposed to less oxygen when transferring, compared to a siphon.July 30, 2016It's okSiphonless feature is great. Super easy to clean or dry hop. Lid doesn't seal/stay shut on it's own. I had to hook up clamps to keep it on. That works but it's a bummer that I have to do thatMay 2, 2017Purchased
1 year agoBigmouth BubblerThe screw on lid leaked pretty bad but the new style lid works much better. Nice not having to mess with auto siphon and great when dry hopping and cleaning.March 6, 2016OK, got a solution for lids popping out......I recently purchased a 5 gal siphonless Big Mouth Bubbler for use as a secondary fermentor. I read many reviews complaining about the new push-on lids popping-up and/or popping-out. I implemented an easy solution to this problem on my first use of the new secondary. That was to utilize a paint stirring stick stuck through the harness handles and across the top of the lid to hold it in place (wet or dry). I slightly off-set it to allow for a fermentation lock. The lid hasn't moved in weeks. See enclosed photos.
I hope this helps others with their popping lid issues.
I would have given a 5-star, but have not yet drained the secondary to see how the siphonless actually works and cleans-up. Could be worse that siphoning, we'll see........March 27, 2017Purchased
1 year agoLid Keeps Popping OffI bought this as a secondary fermenter. Even in secondary, there's just enough CO2 to push the lid up. I'd consider using this in the future as a bottler, but never again as a fermenter. Very disappointed.October 10, 2017lid pops off.I would give this thing 5 stars if the lid did not pop off. Even sitting on the shelf it will not stay on. I have to put tape on it when I use it. I looked for a screw on lid to purchase but didn't see one .May 4, 2017VERY HANDYI like the fact that you can easily reach in and clean.its light weight so that picking this up is easyMarch 23, 2016FINALLY!!!!so they finally did this!!!!...I had to drill out both of my siphon bubblers to install a tap... great idea here!! these are the best fermenters out there, you can watch your fermentation and easy clean up when you are done. highly recommended!!January 20, 2016Siphon less big mouth bubblerThe spigot makes moving the brew from one container to another much easierDecember 25, 2015Bad seal, bad productThe rubber seal for the lid does not seal properly and opens up constantly. Would not recommend and would never buy this excuse for a product ever again.March 31, 2017Purchased

Browse 6 questions Browse 6 questions and 25 answersCould I skip bottling bucket, and bottle straight from this if I use it as a secondary?BEST ANSWER: Even when you use it as a secondary fermenter you will get trub at the bottom and while the BMB does good at draining the beer from the top and leaving the trub undisturbed. if you add your bottling sugar, and then stir up the trub it will defeat the purpose. if you are using bottling tablets or carbonation drops then you would not have to disturb the trub and could bottle directly from the valve. hope this helps. CheersWhat is the diameter of the opening?BEST ANSWER: Hey Jim,
Thank you for choosing Midwest Supplies! The top opening has an inside diameter of 5.5" the hole for the spigot is 1". I hope that this helps, have a great day!How much wort is left when you drain the fermenter using the valve?BEST ANSWER: Not much. It seems to be at the perfect height--right above the cake. I'm really happy with mine--way better than a bucket. I've actually got two more on the way.Can I use this for kombucha or is the acidity too high?BEST ANSWER: It is possible, but we would recommend using glass big mouth bubblers for kombucha.Can I buy the valves separately?BEST ANSWER: Yes that is SKU# 40794 Bottling SpigotDoes it work as a secondary?BEST ANSWER: Sure, it makes a very good secondary vessel for 5 gallon batches of beer or wine. You can then move the liquid to your bottling bucket with the spigot and a piece of tubing, to eliminate the siphoning. -Mike W, Midwest Supplies
