The Fermonster is a brand new fermenter designed specifically for fermentation. MoreBeer! gave product feedback for over 2 years of development and we think they nailed the design. The large lid allows for easy filling and makes hop or oak additions a breeze. The smooth sides are fantastic for sanitization - no ribs or texture to collect yeast or bacteria. The punted bottom allows sediment to collect to the sides so that you can siphon liquid from the center.  Because they are made from virgin PET plastic they nearly unbreakable and a lot safer than similar glass carboys. Also notice the conical top which reduces surface area if you plan to store beer or wine long term.

These fermenters are ported but do not come with a spigot. FE347 is the plastic spigot we recommend along with this fermenter.

Made from heavy PET plastic, the same material used in 2 L soda bottles, which is nearly impermeable to oxygen penetration.  Due to the thickness of the material and the overall geometry the Fermonster does not require ribs or dimples for stability.  That results in a super smooth interior surface that reduces yeast and sediment buildup making it the easiest to clean, most sanitary PET carboy on the market.  The huge 4" opening makes filling a breeze, and cleanup is as easy as wiping down the inside.

These fermentors are completely air-tight 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.

What does "ported" mean? Does the fermenter have a hole such that a spigot is required?
Tom Mosher on Apr 24, 2021
BEST ANSWER: Yes. A ported FerMonster will come with a 7/8" hole for a standard plastic spigot.
Will the FE347 bucket spigot work on this carboy?
Jon Davison on Nov 25, 2020
BEST ANSWER: That's the one that is recommended in the Description text.

Beats glass by a mile
Lightweight, simple to clean, no need for a siphon, fits a nice big stainless hop spider for dry hopping, and it bounces if you drop it. What more could you ask for.

Carboy wine storage
The containers work very well for aging the wine until you need to top off your oak barrells. I have been able to keep wine in one of them for about 1 1/2 years with no issues. Just make sure the gasket is properly set when you put on the top.

Perfectly proportioned
I like to brew 2.5 gallons when trying a new recipe (In case I’m not thrilled with the end product). This Carboy is just right for such occasions!
