Description

Details

Purpose-designed from head to toe, Big Mouth Plastic features improved strength and durability through a decreased base diameter, punted bottom and 3” thick anti-flex ribs. Equipped with a taller body and smaller footprint, Big Mouth Plastic is ultra-storeable, fitting easily inside a standard bucket to take up less precious brewing space. Constructed from food-grade PET, Big Mouth Plastic features gallon graduation marks for instant volume measurement, plus a punted bottom to efficiently settle out yeast and promote crystal-clear finished fermentations. And, of course, its revolutionary wide mouth eliminates glugging and enables hands-on cleaning for a faster, cleaner clean. Finally, get your hands wet.

The new Big Mouth Universal Lid (included) fits all Big Mouth Bubbler® Fermentors, and has ribbed silicone rings ensure a completely air-tight seal. Upgrade to a dual-port lid plate for continuous thermowell monitoring in one port to sustain constant ideal fermentation temperatures and take gravity readings without ever removing the lid.

Earth-conscious design. We have thoroughly planned out every last feature of this innovative product, right down to it’s physical construction. After untold amounts of research into the properties of PET plastic, we fanatically chose to make the Big Mouth Bubbler™ with as little plastic as possible while still maintaining a high degree of structural integrity and brute strength. What does this all mean? It means that the impact to our planet Earth is as minimal as possible. We call this a win-win situation. Check out the Plastic Big Mouth Bubbler™ for yourself. You will never go back to a traditional style carboy again.

**Important Note: Do not fill any Plastic Big Mouth Bubbler® fermenters with very hot liquid - temp should not exceed 140 degrees Farenheit (60 celcius)

You will also need a Small Universal Carboy Bung (not Included) - drilled or solid.

The Carboy Dryer is compatible with the Big Mouth Bubbler® when used in an inverted position.

Used to be the best
I would replace every one of my buckets and carboys with Big Mouth Bubblers if they went back to a screw type lid. The universal fit lids do not stay put reliably. An outstanding product ruined.

I love that I can watch the fermentation process.

Poor Seals
Every so often these are the freebie that MWS provides sales with. Although easy to clean and sanitize, the seals on the fermentor don't stay put. Whenever I used one of these I had to weigh down the top with jugs and bungee cords. Any type of pressure blows off the whole lid. If you accommodate for this it's fine, but otherwise I'll stick with buckets or carboys, I can soak clean.

Big Mouth Bubbler
Needed to add some to my gear. Use for secondary fermentation and clearing as it is easy to see. Do like the old lids better, but since I use after fermentation is over I have no problems with lids staying on.

Love the Plastic Bubbler, lightweight and easy to clean.
Works great, no worry about dropping it, easy to clean and light weight. If you want to watch active fermentation this is possible versus a bucket.
Buy the carry harness to move it easier when full and protect the bottom from the concrete floor.

Call a spade a spade
I own two BMBs with the original lids and they work great. Several dozen batches of beer, wine and cider and not a spoil yet. This new lid is ridiculously problematic. I have scoured the internet for all the "fixes" (something I never had to do with the old lid). There are several things you can try that have not worked for me... airdry everything after sanitizing. Turn the gasket upside down/inside out/outside upside hit me on the flip side. It just doesn't work and I have to put weight on it to keep the lid on.

Also I've scoured for the original lid or suitable replacements and the F@stFerment conical lids don't actually fit the BMB properly so beware following that Reddit post that says they do... It is a slight improvement but still not at the level of the original. I'm not sure why they won't just sell the original lids or offer them as an option...

works but not a favorite
I got one of these as a replacement for the glass 6.5 gallon big mouth that I ordered to pair with the Big Mouth Depth Charge. The lid opening on the glass unit was out of round and would not accept the universal type lid that is part of the depth charge. The universal lid fits the plastic unit, though I would question it's security, especially under pressure from an active fermentation. I'm also not loving the thinness of the plastic material. Sure it saves weight over the glass, but the sides are so thin that when pushing the universal lid on, the sidewalls of the plastic Big Mouth begin to flex and bow. I've used large plastic water jugs for years to fill my aquarium and never been able to flex the sides of those by pushing down on the top, which tells me this plastic on this is just too thin. Overall, it works for now to finish off the batch I have going, but I'm going to go looking for a glass unit that has a properly rounded lid opening for the next batch.

Are they BPA and or BPS free?
J A on Mar 31, 2016
BEST ANSWER: Yes
Does the big mouth bubbler have a gasket for the lid?
A shopper on Feb 9, 2017
BEST ANSWER: No, there is no gasket included for the lid. It does loosen a slight bit during fermentation, which causes the airlock to lose pressure, but the brew continues just fine. I tighten the lid every other day and it pressurizes the airlock fine.
Can you place it inside a standard fermenting bucket to move it around when full, instead of the specialty designed strap.
D B on Apr 1, 2016
BEST ANSWER: This is not recommended. The Big Mouth Bubbler is slightly too wide to fit wholly inside the bucket.
What size cork/stopper does this take?
A shopper on Mar 17, 2017
BEST ANSWER: These carboys will take a "small universal stopper" ( SKU 7081 ) or a #6.5 stopper ( SKU SD65 ). -Mike W, Midwest Supplies
if you put in 6.5 gal, does that fill it all the way to the top of does that leave some headspace?
A shopper on Aug 14, 2018
BEST ANSWER: The top mark(line) is 6 gal. If you go 1/2 gal past that its only to the top of the curve, or bottom of spout. It still gives you a little room
What are the outside dimensions?
K S on Aug 9, 2016
BEST ANSWER: They are about 11" in diameter and about 22" tall (without the airlock).
Used vanilla in secondary and I cannot get rid of the smell, how do I clean this?
