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®.

4.5 / 5.013 ReviewsVERY HANDYI like the fact that you can easily reach in and clean.its light weight so that picking this up is easyMarch 23, 2016easy 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, 2016Siphon less big mouth bubblerThe spigot makes moving the brew from one container to another much easierDecember 25, 2015Great product!Great for those who use secondary in their process. Bottling day is fast and efficient.January 17, 2017Purchased
4 months agoFINALLY!!!!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, 2016Sipohonless 5 gal.Works great as a secondary fermenter. I can transfer directly from this to my keg via the valve so much easier than using a siphon.January 6, 2017Purchased
4 months agoGreat secondary or small batch primaryI use the 5 gallon plastic big mouth as my secondary after primary fermentation in the 6.5 gal. Easy to monitor the clarity and easy to transfer to my bottling bucket or a keg. The screw-on ring and ported lid seals well, I never have had any issues despite reading other reviews complaining of leaks.July 31, 2016Worked as advertised!Worked as advertised!January 7, 2016Great for secondary fermentorNeeded another secondary fermentor and it works great. The port is also an added benefit when racking or doing a transfer to a bottling bucket.February 23, 2016Bigmouth 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, 2016
- Customer Q&A
Browse 5 questions Browse 5 questions and 22 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 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
