Your wort is protected during fermentation by innovative flared-fitting lid construction, creating an airtight seal between the lid plate and top of the fermentor.
Superior to a carboy, the Big Mouth Bubbler® Plastic prevents off-flavors by enabling you to keep the lid on during testing and transfer, avoiding exposure to oxygen with standard-sized ports that can accommodate most fermentation-monitoring equipment.
Designed for flexible fermentations, lid plates are interchangeable and the lid ring is universally compatible with all fermentor capacities and lid-plate configurations. The modular lid is optimal for the cleanest clean, easily taken apart so you can get down into every last nook and cranny. Say goodbye to your carboys for good!

- Hot liquid will destroy this fermenter Review by mr2beers
Before my first time using I sanitized with star san and then quickly rinsed with about 1/4 gallon of hot water that I had boiled on the stove. After only about 5 seconds of contact the whole carboy buckled and was completely ruined! My fault of course because there is a warning on the label to not exceed 140 degrees F (although it's such small print I did not see it).
Buyers should be aware that these are not very resilient and can not be treated the same as a regular plastic bucket fermenter or glass carboy.

- Just About Perfect Fit & Function Review by Dan
Just finished the clean-up after my first fermentation in the Big Mouth, a dry stout that blew off for three days and made quite a mess. How'd it work? Great! Contrary to some of the reviews of the 6.5-gallon version, the lid sealed just fine, the blowoff tube stayed in place, so all the mess was confined to the bucket at the end of the hose. Nice. When the blowoff ended, a standard bung and airlock fit right into place (hint, though: just like a glass carboy, the lid won't adhere to the bung if either is still wet with sanitizer solution. Let them air dry, or use a clean paper towel--or a piece of sterile gauze if you're really obsessive about sanitation--before putting the bung in the lid).
But the big thing was the clean-up. My previous batch of Irish red was fermented in a standard glass carboy, with the same very enthusiastic yeast... and it took half an hour with a brush and two soaks in Oxi-Clean to get the krausen out of it. The Big Mouth cleaned up in about five minutes. Most of the krausen simply hosed off with warm water from the spray hose in my kitchen sink. Wiping with a standard dishrag cleaned up the rest (if I have any complaint about this product, it's that it doesn't come with the nifty microfiber cleaning rag that accompanies the glass ones) I had been a bit worried that crud might get stuck in the little "bubbles" molded into the sides, but they seem to be quite rounded on the inside and nothing stuck to them.
So overall, I think this is a great product. It fits in my fermentation chamber, it functions well, I can see what's going on inside, and it cleans up in a snap. What more can I ask for? (well, if you must know, how about adding a 3-gallon one with the same diameter? Then I could ferment half-sized batches on the "shelf" above the refrigeration unit in that old freezer).
