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.

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.

I’m glad this was added to this mfg products. The lid can be difficult to remove by hand particularly if any sweet juice is on the seal.

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.
