60 day no hassle return policy. Details

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.

Even if you barely tighten it down, the Fermonster lid takes the might of Thor to loosen it after fermentation
Alex McCool on Nov 28, 2019

sometimes the lids are stuck on really good. usually a hot water rinse loosens them but hope this makes removal easier on my aging hands

Difficult to open the pressurized FerMonster. Brope my airlock and cut my hand trying to open it. Hope this helps.

I tightened the lid too tight a number of times and was hard to remove lid when transferring or kegging without disturbing the sediment at the bottom of the fermonster.

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.

Works - but breaks lids
Don't use this to try an tighten down the lids. You'll crack the lids. If you're having sealing issues, put the lid on the container while it's upside down. That seems to do the best to prevent the o-ring from popping out.Of course - this requires the container to be empty.

Only use this to remove the caps.

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.
