Description

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 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)

I wanted to have two or three small, one gallon carboys on hand while making wine and I didn’t want to use glass jugs.

Based on reviews and research this looked like the best option for small batch fermenting for my use.

Not as high quality as expected
Pros:
* Lightweight!
* Won't shatter like glass.
* Large mouth makes cleaning a piece of cake.
* Slightly larger than 1 gallon, so I can actually bottle nearly that much.

Cons:
* As many have said, the thin walls make me feel like I'm going to collapse or dent it.
* The o-ring provided for the lid doesn't stay on. Pretty sure it's going to fall into my beer, so I threw it away. It keeps a seal without it anyway.
* The dent where the spigot might go is annoying and unnecessary (I'm never putting a spigot on it).
* The larger-than-normal stopper required is not easy to find. I ended up fabricating a 2-hole of the right size and did not enjoy the experience.

The good news and bad news are the same; The carboy is light with a wide mouth. this is easy to work with and clean, but the lack of weight and flexibility makes this carboy difficult to handle when working with it since it will tip over easy and crumble with the slightest of pressure like tightening the lid down or implementing a siphon.

Perfect
Mixed up a 1 gallon batch of Blackberry Mead. The shape and wide mouth opening is perfect for degassing and adding nutrients. Much lighter than glass without the danger of dropping and breaking. Easier to clean than a gallon jug. I like the wide opening for the bung too, don't have to unscrew the lid to take a reading or add to the batch.

Pretty thin plastic
I got my 1 gallon Fermonster in today. I have four of the 6 gallon versions and love them. The 1 gallon versions aren't as thick and flex very easy like a cheap water bottle. I'll do an update after a few uses, but my first impressions aren't looking to great.
