Got a stuck lid on your Fermonster? Get it open much easier with this specially designed lid opener. It easily slides onto the lid and gives you comfortable hand grips to open a stuck lid.

Note: We do not recommend using this tool to tighten the lid because the seal is made by the o-ring and not the pressure between the lid and neck.

Seth on Jun 29, 2019
Can this key be used for fermentassaurus?
BEST ANSWER: The grooves in the lid opener are designed to match up specifically with the grooves of the Fermonster lid, and will not work with the fermentasaurus lid.

Has helped a lot
The fermenters are great, but do have a tendency to stick. even with this you have to find a way to hold the fermenter (without squeezing it) and turn. better than trying to do it by hand

This is a great tool for me to use being 91 years young it sure makes unscrewing a lid easier for me.

Much needed Fermonster tool!
This helps with breaking the Fermonster lid free after fermentation. I have had several instances where the lid has tightened, making it very difficult to free the lid to add additions, etc.

Buy one.
This is a mandatory piece of equipment. I just picked up a bunch of fermonsters to try them out. Like every review said, for whatever reason, they are hard to open by hand. Luckily, I picked one of these up, because, you know, tools. Get one.

This a must have
This is a perfect tool to an terrible lid/cap design. It made the fermonsters not as bad to use. Gets the cap tighter to seal and removing the overtightened cap off much much much easier. I don't have to wrestle the carboy now

Should be included with every fermonster. I used a strap wrench for a while not knowing this existed. Works great.

Great Tool for Fermonster
After having trouble opening my Fermonsters, I saw this tool. Economical and does the job. Can't picture not having one now.

Fermonster Lid Opener
If you have bought a Fermonster this is a must have item. I lived without one for a couple of months. I did not see this when I bought my Fermonster, but when I saw it I knew I must have it. It makes opening and tightening the Fermonster so easy which to do with your own hands is a little bit difficult.
