5 gallon bib mouth bubbler
Love It!! I use the 6.5 gallon for primary and this for secondary...LOVE Both of them. I know people say they have trouble with the lid coming off...here's a 10 cent fix...cut three pieces of 2x6s about 4 inches long. Put two pieces on their side on each side of the fermenter lid...next lay the third piece over the top and place anything heavy on the top. Problem solved!! I love being able to see what is going on inside the fermenter. Need to be careful when cleaning as plastic is easy to scratch...bad

Not bad, I'll get the glass ones eventually.
This was part of a special a couple months back. I've tried it once and it worked well. I used it for a 3 week primary & transfered to a bottling bucket for bottling. I got almost no particles on the transfer. Actually less than when using the auto siphon. I was concerned about the spigot seal holding. No issues, it didn't leak.

My gripe is the lid. As others have said, it doesn't seem to stay seated. Mine didn't actually come out, but on brew day after installing lid & airlock, it raised up about 1/2 way to being unseated. My solution was to hold it down with electrical tape. Next brew I think I'm going to try a light duty ratchet strap.

5 gal Big Mouth!
I love the 5 gal Big Mouth Ported, as I use it for secondary fermentation as all the excitement of the primary fermentation has settled down. It makes going to bottle a real pleasure.

Better than glass on the back
Been using glass for a long time but this is so much easier on the back.

Handy secondary fermentor.
The Big Mouth Bubbler came promptly with the rest of my order from MIDWEST Supplies. It works great as a secondary fermentor when I do 5 gallon batches. I love having the port on the bottom as it removes the need to siphon. The valve is positioned high enough not to pick up the sediment off the bottom. It’s easy to clean because of the big mouth. I’ve never had any issues with the lids staying put as some have suggested. There shouldn’t be any pressure build up if you’re using an airlock anyhow. Can’t go wrong with this!

Nice fermenter that would be great with better lid
Got it free as a promotional item. Great as a secondary and makes dry hopping nice and easy. I’m with the others in that the lid won’t stay in place and I’ve had to tape it down.

The lid popping is for real, but all else is great
The lid popping is for real, but all else is great so be prepared to make one of the many inexpensive modifications you can find online. I had some spare cat5 cable I used to tie it down after it popped.

Ridiculously brittle plastic
I do home brewing as well as commercial brewing, and In theory I love the idea of this fermenter. I love the wide opening for easy access. There are just a couple flaws that are easily fixable for future manufacturing. The biggest is that the plastic is very thin and brittle. From just mixing around the wort to Oxidize while pitching the yeast, the wort weight cracked the fermentor. I would easily pay 10 bucks more for thicker plastic, increasing the life tremendously. Also, the bubble indent design. Guys, this increases the chances of infection tremendously! Having little indents all on the inside, makes cleaning 89 times more difficult!...and I know home brewers could care less about a bubble design on their fermenter. Not having these will lower your cost too! You're so close to an epic design Big Mouth! PS: I lost a fermentor, and stressed for 2 weeks thinking my wort was infected from the accident. Bummer

Had a slight problem with the delivery, but Midwest Supplies quickly solved the problem. The only problem I had with the Bubbler was a seeping around the valve at the bottom. Removing it and trimming a burr off where it was drilled solved the problem. Definitely recommend!

Bubbler killed the carboy
I got the 5 gallon Bubbler to use as a secondary fermentor. I already have a 6.5 Bubbler, and the transfer to the 5 gallon unit allows me to brew another batch sooner, and reduces the amount of oxygen in the head space once fermentation has settled down. I can bottle right out of the 5 gallon unit after adding the primer, an added feature I like. The Bubblers clean up easily, no chance of breakage, and a lot less weight than glass. The only drawback is the new lid, it won't stay put when wet. You just have to plan ahead so the sanitizing solution has time to dry. At your suggestion I inverted the gasket and that helps. So if you want to start a terrarium, I've got a carboy you can have!
p.s. your photo is a lot better than any one I'd submit.

Does it work as a secondary?
P S on May 10, 2016
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
Could I skip bottling bucket, and bottle straight from this if I use it as a secondary?
MARK S on Mar 27, 2017
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. Cheers
Does this need an airlock?
A shopper on Sep 21, 2018
BEST ANSWER: Yes, it does. Note: You'll want to make sure you remove the airlock before transferring your finished beer, to prevent a vacuum effect that will draw sanitizer from the airlock into the fermenter.
What is the diameter of the opening?
J I on Jan 31, 2016
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?
J I on Feb 1, 2016
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?
A shopper on Dec 3, 2017
BEST ANSWER: It is possible, but we would recommend using glass big mouth bubblers for kombucha.
Can I buy the valves separately?
Deron A on Nov 14, 2016
BEST ANSWER: Yes that is SKU# 40794 Bottling Spigot
