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.

The lids can get tight on the Fermonster. This should help remove them.

Sometimes I'm a weak little person who has trouble opening things.

I am hoping it will fit my 3 gallon Speidel fermenters

lids get stuck
Chandler O on May 9, 2018
Pretty much a must. You have to seal the lid tightly to get the airlock to perc.
Shaun V on Apr 26, 2018
seems better than using pliers
Bradley M on Apr 25, 2018
I read that these are necessary for easy opening of the fermonster lid.
David P on Apr 19, 2018
Cause the lid sticks worse than thighs to vinyl car seats in the summertime.
Dale W on Apr 13, 2018
Because the Fermonster is impossible to open, you should sell this with the fermenter by default.
Trevor G F on Apr 3, 2018
Those fermonsters are hard to open I think this will do the trick.
Matt H on Mar 30, 2018
Makes taking the lid off of the fermonster easier. Lid tends to stick.

Because the lid to my fermonster gets stuck
Valued C on Mar 16, 2018
These plastic lids get stuck on pretty easy after a week in primary. This looks more appropriate than the hammer and flat head screwdriver I normally use ;)
Christopher B on Mar 16, 2018
Because you can't open the fermonsters to save your life
Seth H on Mar 6, 2018
it is a good help
jimmy s on Mar 1, 2018
Fermonsters are great, but the lids can be hard to open once fermentation has started. This little opener gives you just the leverage you need to open the fermonsters easily.
Mathew C on Feb 14, 2018

Dwane C on Nov 21, 2018
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.

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.

Get one if you get a fermonster.
I recommend getting this if you get a fermonster. I also recommend not getting a fermonster. It's hard to get the lid off, which is why you need this tool.

Almost a necessary tool
Works great. One should be included with every Fermonster purchase. Without it? Getting the lid off can be a real treat.

Must have opener
This little device makes taking off the Fermonster lids incredibly easy. Before I had this I constantly struggled to get the lids off, especially with one hand.

Where has this been?
There is nothing more frustrating than not being able to open your fermenter.... The Fermonster lid has stuck on every batch I've put in it, until now. Worth every penny.
