Carboys are great, but they have some issues: They require funnels to get liquid in, and cleaning brushes to clean up after.  They hold a decent volume, but all are a bit undersized for fermentation, and have no inherent measuring system.  Glass Carboys are breakable, while plastic carboys scratch with the first brush cleaning.  The Fermonster leaves all these problems behind!

These ported versions come with our plastic spigot (FE347), allowing for easy racking and sampling!

These Fermonster Plastic Carboy Fermenters are made from heavy PET plastic, the same used in 2 L soda bottles, which is nearly impermeable to oxygen penetration. The huge 4" opening makes filling a breeze, and cleanup is as easy as wiping down the inside. Glass carboys are fragile, and this is nothing like that.  The hefty plastic construction will hold up to brew day abuse.

These fermentors are completely air-tight; the bodies constructed of heavy, oxygen impervious P.E.T. plastic, and the lids sealed tight with an O-Ring.  Additional O-Rings and Lids both with and without holes are available for purchase, see our You Might Also Need items below.


  • 4" inner diameter wide mouth carboy - easy to clean!
  • Food grade PET plastic construction is nearly impermeable to oxygen penetration
  • No hard to clean dimples or ribs
  • Punted bottom
  • O-Ring and Lid with one hole is included (Fits #10 Stopper)
  • Additional O-Rings and Lids available
  • Weight: 0.6 lbs
  • Temperature Limit: 140° F
  • Height: 9.45 inches
  • Diameter: 6.7 inches
  • Completely taste and odor free
  • Perfect for Beer, Wine, Cider, Mead, Kombucha or any other fermented beverage!
  • Thick walls for better oxygen barrier.

Works great as a secondary fermenter for sour beers. I add my adjuncts to this and then rack the base beer over the top. After 2 weeks to 2 months it is time to bottle.

Planning to use this for cider and I will bottle directly from the spigot to help avoid oxidation.

Got it for a kombucha continuous brewing system. Might get more to have on hand to make tepache or other concoctions

Easier to handle than glass, and the spigot should mean no siphoning!

I like the idea of spigot to eliminate siphoning.

how much brew will this actually hold? Is it 1.4 gallons?
Aaron Pittman on May 22, 2020
BEST ANSWER: This fermenter is designed to hold 1 gallon with a little headspace for krausen. In total it will hold about 1.2 gallons if you fill it all the way to the top.
Does the spigot have a sediment blocker?
Andrew Butler on Apr 5, 2021
BEST ANSWER: Not sure what you mean by “sediment blocker.” The spigot is positioned some distance from the base though, so there’s room for a lot of sediment below the spigot. I use mine for kombucha so don’t have to worry about sediment.
Does it hold exactly 1 gallon of liquid, or is there additional space for the krausen?
David Basham on Nov 17, 2019
BEST ANSWER: There is ullage above one gallon for krausen. These were fairly successful and economical for doing side-by-side fermentation trials. However 1) the side walls are thin and flimsy like a PET soda bottle, 2) I did have some trouble getting the spigots to seal, so test those before filling them with fermentables, and 3) I saw no action on the fermentation lock: not sure if the stopper made a poor seal with the cap, or if the screw-top lid seals poorly. Not a big deal but an inconvenience.

1 gal Fermonster
Decent one gallon fermenter. Would be much better if a thicker plastic was used. The thickness is about the same as a 2L bottle, but is more flimsy since it's twice the size. Currently have two batches of cider in them. Hopefully it will last for a few years but not sure if it will.

It's just ok
I like it, but I don't think it's going to last. Everytime I open the spigot I am afraid it's going to break the carboy. So I have to use both hands to hold the base of spigot still and turn it.

Looks are deceiving
The plastic in this fermentor is very thin and I know this will not last. Has I known this previously I would have ordered something more durable.

Cheap and Flimsy
The plastic is flimsier than I expected, and the o-ring won't stay in place. The lids come with ludicrously large holes meaning that you're likely to have to buy stoppers specifically to work with these fermenters. Bottom line is they just aren't worth the price.
