DetailsThe fermentor that started it all, reinvented again! We’ve taken the revolutionary Big Mouth Bubbler® glass and re-engineered it with the help of world-class Polish master glassmakers to ensure sturdy, solid, superior craftsmanship.
Extra-thick glass eliminates oxygen permeation and keeps your brew safe. Banish bugs and bacteria with perfectly air-tight seals from a carefully ground, completely smooth and obsessively flat neck top.
In the evolution of Big Mouth Bubbler®, we’ve added some perks! Instantly measure volume with gallon graduation marks. Easier transfer of clear beer with a taller, narrower body while ensuring less liquid is left behind.
Say goodbye to that awkward brush and give your fermentor the deep-clean your beer deserves. Scrub off any unseen biofilm. Effortlessly wipe away crusted krausen in just a couple of carefree minutes.
Bid your funnel and siphon sayonara! Pour cooled wort directly from your kettle into the Big Mouth Bubbler® for instant transfers. Pitch yeast without it running down the sides of your fermentor. Easily add flavorings to secondary, and then just as easily remove them!
Last but not least, you asked and we listened—more space for the adhesive FermagraF° LCD thermometer than any other glass fermentor! The most obsessively engineered glass fermentor ever created—we are proud and excited to introduce the new and improved Big Mouth Bubbler® EVO 2.
Caution: Big Mouth Bubbler® is a large hand-formed glass item that can be easily damaged if not used with proper care and handling. It may have variations in shape and thickness, and will show the normal bubbling characteristics of hand-formed glass. Extreme changes in temperature or sudden contact with hard surfaces may cause glass to crack. Handle with care–we strongly recommend using the Big Mouth Bubbler® carrying harness for increased safety and ease of handling.
Note: We still strongly recommend the Big Mouth Bubbler® carrying harness.

3.8 / 5.06 ReviewsVery good qualityI bought this fermenter because I have older Big Mouth Bubblers and have been happy with them. I also have the newer style 6.5 gal without the screw lid and am not happy with it, so once I saw the 5-gal with the screw lid I bought another right away. This particular one seems to be even better quality than my previous ones as the glass seems much thicker. I just wish they offered the 6.5 gal with the screw lid too.October 28, 2018Purchased
4 months agoMarketing GaloreI bought this because of the ad video for the Maelstrom stir plate which shows it being used for large starters. It works well in this regard. I have two complaints about it. Is the marketing hype for this product so important that the lettering and bubbles had to be formed into the glass? Cleaning this fermenter is made considerably more difficult because of all the indentations on the inside glass surface. My second complaint is about the lid. It seems that in the eight months or so since I bought mine they've made a change to the lid. Mine came with a press in lid with a silicone band seal. It likes to pop out when you press it down. Never stays securely down. I guess it seals but it seams like a poor design. Nitpicky stuff but for the price tag this fermenter should be better.

1 year agoServiceThe big mouth bubbler is a great tool, very handy. Midwest delivered it with no gasket for the lid, yet another issue from Midwest. The product is great the service not so much!January 22, 2016Response from Midwest SuppliesHi Greg, I apologize that was missing but I see we did get a replacement sent to you and it looks like that was delivered on the 13th. Is that working alright for you?November 2, 2016Midwest Suppliesworks great no problemsworks great no problemsDecember 28, 2015Bacteria magnetSee all those little bubble shaped dimples all over the sides? Even with easy access for cleaning, the yeast/sludge/krausen sticks in them and is very difficult to keep clean. Who thought up that design?July 24, 2015

Browse 4 questions Browse 4 questions and 14 answersHow tall and how wide is this?I am thinking abbot buying this but I am concerned that it will get damaged in delivery, has anyone had any problems with this? Is it mailed with lots of padding too keep it safe?BEST ANSWER: Yes, mine was shipped with padding and arrived without issue. I did order a 3 gallon glass carboy that got damaged during shipping but midwestsupplies shipped another one out immediately without question.The review mentions that the inside of the fermenter is not smooth, that the bubbles that are part of the design of the fermenter also make the inside of the fermenter not smooth. Is that true?BEST ANSWER: The only "bubbles" in the glass on my fermenter are on the outside of the vessel. The inside is very smooth on my unit. However, the lid doesn't stay put unless I hold it down by tying a shoelace across the handles on the optional nylon web carboy carrier.What is the diameter of the mouth?BEST ANSWER: The diameter of the mouth is 5.25".
