Description

Details

The 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.

Each Big Mouth Bubbler® EVO 2 includes:
  • Big Mouth Bubbler® Glass Fermentor & Threaded Lid*
  • Big Mouth Bubbler® Microfiber Cleaning Cloth
You will also need a Small Universal Carboy Bung (not included) - drilled or solid.

I wish the lid was easier to line up when screwing on. It has a tendency to want to cross-thread. It makes the first fermentation process much easier!

BMB EVO 2
The fermenter itself is great. The screw on lid is flimsy and the gasket on mine didnt seal off the container. Afyer pitching my Krausen was like a volcano and no bubbles came from the air lock as it was seeping out of the lid. Swapped lids with the threadless EVO2 I have. Apparently the threadless ones are a little bit narrower. Had to modify the silicon seal to get it to work. BMB needs to figure the lid situation out.

Go with Glass!
Easier to clean than plastic and does not leave tiny scratches for microbes to grow! This is pretty heavy, especially when full so be sure to put it in a tote during fermentation because you wont be able to move it after its full. I suggest buying a carboy strap for this big boy!

Wonderful!
I got one of these last year and it has been great. I still have my old glass carboy, but this thing has taken over its duties. When I read the reviews, everybody was bitching about the lid and how it wouldn't stay in place. I got mine and discovered it had the screw-on lid, even though that kind had supposedly been discontinued. I had to order the smaller drilled stopper for the air lock, but it has been a champ. Sure is easier to clean than ramming a brush down the old carboy.

White wine fermentation
I used the Big Mouth for primary fermentation of white wine. It has adequate volume to do a 23 liter primary, but if you have skins to add for a red wine this will not be big enough. I like the idea of using glass for fermentation instead of the plastic buckets. The lid that came with it was a screw on lid. Even though I tried several times the screw on lid would not provide a tight seal. I'm currently looking for some type gasket to use. But with a primary wine fermentation you don't actually need a tight seal until near the end of primary fermentation. I like the product and would like it more if I could get the lid to seal.

Great Item!
Glass is by far the best over plastic any day. I love this item and it does the job! The larger opening makes it easy to clean

lid opening not round
I purchased one of these for my latest batch to pair with the Big Mouth Depth Charge. I couldn't get the Depth Charge to work with this unit because the Depth Charge uses the push in type universal lid and the opening on this glass 6.5 gallon piece was out of round by about 1/8" and would not allow the universal lid to fit in. I'm not sure if the outer portion of the neck with the threads is round either because the lid is very difficult to screw on compared to my 5 gallon gen 1 Big Mouth with the grey lid. Midwest was great about getting me a plastic 6.5 gallon to work with the Depth Charge so I could finish the batch in progress, but it's disappointing to see products that are designed to work with each other not do so due to quality control issues.

Great carboy, must weigh down the lid.
Love the big opening on the top. Easier to clean than other glass carboys. The lid needs to be wieghted down. I use an Olympic 2.5 pound weight. Some people really struggle with the lid and gasket. But with a slight modification I made I love it.
Flanders Red with Tart cherries.  
Cherry pie flavored sour beer.
Added Olympic 2.5 lb weight to make the lid more secure.  Works great with the weight.

Will a 6.5gal work for 5gal brews or will I absolutely need a 5gal for the secondary fermentation? I'm trying to save as much space as possible. Is there a way to use the 6.5gal for the primary and secondary fermentation?
Christina B on Dec 5, 2016
BEST ANSWER: You can use a larger size vessel to ferment in primary or secondary but you will need two separate vessels one for primary and one for secondary. The big mouth fermenters have to be taped on the top during primary around the rim the cap seems to pop off due to pressure from CO2 but they are much easier to clean I also recommend getting the plastic drying stand for the fermenter it works for either big mouth fermenters as well.
can I get the dimensions of the EVO 2- 6.5 gallon? I am trying to see if this will fit in my mini fridge. I am currently using 6 gallon glass carboys.
K U on Jul 27, 2016
BEST ANSWER: It is about 13" in diameter, and about 19" tall (without air lock or blow off).
Can I use this for a primary fermentor for a 6 gallon wine kit??
A shopper on Jan 3, 2017
BEST ANSWER: A 6 gal batch may be tight. Not much room for yeast cap. It will work if your yeast doesn't overflow it. I assume the wine is a juice kit and not fresh fruit? 1/2 gal of spare room just seems too little for primary fermentation. I have had 5 hal of beer blow the top off with yeast/foam at the top. You usually want 25% - 30% headroom for a primary fermenter just to keep the messes down.
can the manufact. drill and install a spigot?
A shopper on Jan 28, 2018
BEST ANSWER: The Evo 2 for a short time sold a spigot version. I have a 5 gallon Evo 2 Glass carboy with a spigot. Then a bunch of less then perfect spigot Evo 2 were discounted thru Northern Brewer. Now NB no longer sales spigot glass carboys. Just plastic big mouth bubblers. Drilling glass must be difficult or they would still be offered. So the short answer would be New.
Is there a stopper for the big mouth bubbler that allows the use of a thermowell along with the airlock?
J O on Nov 30, 2015
BEST ANSWER: Most thermowell's come with a standard size (dia.)stopper, with 2 holes. 1 for the air lock and 1 for the thermowell. The TW I bought from another vendor was this way. That being said, the holes for a TW stopper are smaller then a standard 2 hole stopper you get from your local brew supply store. hope this helps.
Will the depth charge accessory work with the screw on lid?

BEST ANSWER: Hi there- it does not work with the screw on lid. Cheers!
I'm confused... this description says 6.5 gallon glass w/ threaded lid, but a lot of the reviews talk about the universal plug-style lid popping out. Does this come with the gray threaded screw-on lid, or does it come with the blue universal lid? I only want it if it has screw-on lid...
A shopper on Feb 23, 2018
BEST ANSWER: This product is currently being sold with the screw-on lid. Cheers!
Can you use the 6.5gal for primary and secondary fermentation or do I absolutely have to get a second 5 gal carboy for the secondary fermentation? I'm tight on space so I'd rather find a way to make one work if it's possible.
