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

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.  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.

What size tubing will fit the spigot?
Ray Pirc on Jul 11, 2018
BEST ANSWER: 3/8 OD tubing works for the spigot.
Does the washer on the spigot work best inside or outside the carboy?
Dan Ozenberger on Dec 9, 2020
BEST ANSWER: If you look at the spigot when it arrived, it looks exactly like the product FE347 --> https://www.morebeer.com/products/plastic-spigot-bucket.html. The directions for FE347 say to put it on the outside with "the gasket against the exterior of the bucket". My assumption would be that the tapered side goes as it shows in the picture and goes against the bucket/FerMonster. Still, the best long term answer is to buy two FE348 -> https://www.morebeer.com/products/replacement-washer-spigot.html -- washers and put one on both sides.
Has anyone had to use a blow off tube and if so what OD?
Michael Cundiff on Feb 25, 2018
BEST ANSWER: Hi Michael,
I've had this fermenter for over a year fermenting 5.5 and 6 gal batches. With aggressive yeast I'll attach a blow off tube. Simply insert a 1/2 OD tube into the size #10 stopper that is a recommended purchase from Morebeer. It creates an airtight fi!

Easy to clean, no problems with the spigot for me
no leaks from the spigot on first install, just hand tightened with the gasket on the outside as instructed by morebeer.

The spigot makes taking samples a breeze. Just remember to pop open the air lock so the negative pressure doesn't suck the airlock contents down into the fermentor.

Thinner than I would like
The sides dent in if not careful when moving full fermenter. And some did not pop back out.

Upgrade from the standard Carboy
If you're sticking with a PET carboy this one is tough to beat. Wide mouth, plenty of capacity, and easy to clean.

This fermenter is OK but not as sturdy as the ‘Better Bottle’
Getting the spigot sealed took a couple of tries. I already ordered a solid lid and a carry strap.
On the plus side, straight surfaces should be easy to clean.

Easy racking, racking it slow
Love this thing. Using a brewjacket with them. Racking made easy, easy to clean. Extra headspace is nice for high gravity beers.

easier than a carboy
I love these fermonsters in the 7 gallon size. They're easy to clean because I can fit my arm most of the way in to scrub. The spigotted option is great for moving liquids to a secondary fermenter or bottling and it's off the bottom by enough to leave trub inside.
