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.

I love my 7-gal FerMonster! I'm adding a 2nd with the spigot for zero-O2 gravity samples.

Need moar fermenters and prefer the monsters, though the opening could be a little larger for reaching the bottom. Good price on larger spigotted size.
Adrian O on Jul 23, 2021
I hope it fits in my fermentor

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!
Has anyone already measured out the heights/distances for each gallon mark? I would like to place a vertical piece of tape with each gallon marked off. Thank you.
Robb Denney on Aug 15, 2021
BEST ANSWER: This fermenter has already the 5gal and 6 gal marks. You can measure that distance and use it to mark 4 through 1 gals.

So Much Better Than a Bucket!
Tall to avoid bubble over through the airlock. Clear to see what's going on. I put on a temperature indication strip. I didn't realize that room temp and fermenter temp are not the same. Pretty exothermic! Easy to transfer to the keg.

Love them except plastic is a little flimsy and O-ring to thin
Like to be able to see fermentation. Big opening to make it easier to clean good for the price

Light. Easy. No complaints.
So far so good! I have my first beer fermenting in the FerMonster now. Super easy to use and cool to be able to watch the magic happen (moving away from white buckets). The varying strap is super helpful and the thermowell stopper is perfect. Looking forward to the next batch!

So well designed
This may be your first and last fermenter purchase. :) Much easier to clean than the "bubbler" competition. Better seal also. The addition of the spigot is terrific. If you're careful with trub you can go out of the spigot right into the keg liquid quick disconnect with very little o2 pickup. :) Buy it!!!

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.
