The Ported 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 large 7 gallon size was designed to provide ample space for fermentation and you'll find the molded in volume markers super handy for accurate filling. 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 thicknes 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.  The 7 gallon volume is a monster of a fermenter, reducing blowoff issues seen with standard 5 and 6 gallon carboys. Fermonsters are easily moved by hand or consider using our Carboy Carrier for even greater ease of use.

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.

Love these things
Got a second one. First one still working great. I also have the 1 and 3 gallon version. I use the spigot for gravity samples and transfers. Great price. No glass to shatter. Easy to clean with a sponge. I love watching the fermentation. The gasket is kind of a pain. I use a toothpick to remove it and tip of a plastic syringe to push it in to its groove. It seals great.

Highly recommend! wide mouth makes for easy cleaning and the spigot eliminates the need for siphoning! Fermenting and transferring has never been easier!

Great Fermenter
I ordered three of these, and they're fantastic. It's nice to see what's going on with your fermentation.

Good, Bad, and the Ugly
Good: Wide mouth is easy to clean, pitch yeast, had hops/adjuncts, etc.
Bad: They are a bit flimsy when handling, handles would be helpful or more sturdy plastic. Lids are really hard to open by hand if on too tight- they need a custom tool to allow better torque to open easier.
Ugly- the LIDS S***! Too easy to get cross-threaded- even when it looks and feels straight and on tight, many times air leaks out- only after reseating several times with fermentation going through an airlock to see when it finally sits right and starts bubbling. Bought two of the same model- and must have switched the lids because I got no activity through my blow-off tubes until I switched them back and messed with them for about 20 minutes to get them just right so they sealed properly (gasket was firmly in place). POOR DESIGN!!
