19 customers mention "Fit"4 positive15 negative

"...should last forever if not dropped. The lid though, doesn't fit right. Had to tape it down (as others have suggested) to get a proper seal...." Read more

Lid does not stay shut
The product is really cool and holds a lot of soon to be cider but the lid does not stay on. I have even duct taped it shut and I still go in to check on it and the lid has started to come up. I feel like the lid needs to have a redesign because the lid won't stay down and the burper cork hole is kind of big. I think the size and availability to be able to get inside and clean it are amazing. Just has that 1 flaw.

    I bought this to store my 28lb bag of dog food. It works very well and the mouth is wide enough to easily reach in to get the kibble. However, I did not realize when ordering that the lid has a 1" hole in the top, making it not airtight, meaning I will need to get a plug or seal it some other way. But it's very easy on the eyes, unlike the clunky plastic tubs and metal cans that I had been looking at. I was also concerned for the plastic and metal toxicity so glass was the next best choice. I'm not your average reviewer (using this item outside its purpose) but I would recommend this product.

    I was disappointed with a couple of car boys that I ordered recently the typical complaints narrow opening hard to clean and the packaging they sent them offered subpar protection this fermenter on the other hand was in a big box surrounded by air cushion bags inside of another box that had protection on the sides as well as the bottom this thing is sturdy it has abig wide mouth to reach in there and clean my only gripe is the lid could stay on a little bit better but a little bit of vinyl tape and it's fine that stuff's easy to peel off and leaves no residue otherwise I haven't found anything online like this

    Nice thick glass. Fits perfectly in my mini-fridge fermenting vessel. The top does push off, but its designed to do that so that the carboy doesn't explode. If the lid were fixed and a blowoff tube or airlock clogged, the carboy would explode. Then the reviews would be complaining in a MUCH different direction.

    I think that the solution is a 1.25" OD/1" ID blowoff tube. I just ordered that and think it will solve the issue with the lid popping off. I did wire it on very loosely, keeping in mind that I would rather the lid pop off than the carboy explode if/when the tube/air lock clogs.

    Winemakers rejoice! My wife bought me 2 of these, after seeing me cleaning my small mouth glass carboys. The wide mouth will make cleaning a breeze. The caps appear to fit very well and your glass carboy stoppers will fit in the pre-made holes. I haven't used them yet, but I have no doubt that I will be changing my rating from 4 to 5 and buying more.

    The lid does want to pop off under pressure a little piece of tape on each side solved it. Sealed well (evident as why it wants to pop under pressure) which is most important. Easy to clean. Easy to pour in as well. Thick glass very durable. Will purchase another.

    If you like glass carboys you’ll love this carboy’s large opening. I did not rate the stars for flavor as this isn’t something that you eat. One big problem I had was keeping the lid on. This product should come with a lid locking device and airlock with bung. If you buy this carboy you will want to buy a lid lock. Be careful which lid lock you get. There are different sizes out there. I purchased one that didn’t fit. Reduce the rating by two stars for this problem the manufacturer has to be aware of and ignores.

    The glass is good. I love the wide mouth for adding fruits and other ingredients. Can't find any obvious imperfections or week points other than the lid. The lid is terrible! It lifts itself out under it's own pressure. Doesn't lock down and under fermentation pressure it doesn't stand a chance. I turned the lid and got a click and it stayed. Until there was pressure. Tried flipping the seal upside down and did not get a better seal. The pressure pushed it out quickly either way. I had to tape it down. It's a terrible lid design that doesn't work. I resched out to the seller and they told me to try flipping the seal and tried to upsell me on a strap to help keep it down. If you have to flip the seal, it's a bad design to begin with. Also, flipping it didn't work. The 100% satisfaction guarantee is not guaranteed because they know it's a bad design.

    These are great for cleaning and sanitizing. Had one that arrived cracked at the bottom radius and the guys at Northern Brewing credited my account with no problems. I'm getting ready to order my 3rd. They are heavier than the plastic, but I got tired of the light weight plastic ones scratching and eventually cracking. I use these for primary wine fermentors with or without the covers/airlock. Much easier to keep clean and they last forever if you take care of them. : )

    Item arrived safely and in the the time frame that was given. Already in use and will be cleaning it very soon. This should be a lot easier than cleaning a regular carboy/demijohn as you can get your arm inside and get it cleaned up in no time.
    Thanks for the great service !
