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.

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!
What size tubing will fit the spigot?
Ray Pirc on Jul 11, 2018
BEST ANSWER: Small, like 1/4 ID if you stretch it, 3/8-5/16 fits easily

Fantastic! The spigot makes transferring to a secondary fermenter way easier than a siphon or transfer pump. Wish I had started with this!

Few dents but no scrapes. Good to ferment! My current batch of holiday ale fermented with giga yeast overflowed the top with foam, was a small mess, but still cooking!

Huge QoL Improvement without the Big Pricetag
Before this i had solely fermented in glass carboys, but bought this on a whim for a spigot. It probably improved every aspect, from the weight, racking, and cleaning. Everything is better. Hopefully it lasts just as long. Looks like it got a little deformed on the top during shipping, but it still works perfectly!

Perfect fermenter
I purchased this to replace an HDPE opaque fermenter that I've used for 15 years. This Fermonster is very light weight, easy to watch activity in and super easy to clean. You may want to purchase the carboy carrier for it as it is somewhat slick when wet and sudsy. It does have a lip on the top but it requires a bit of finger strength to lift when full. Overall great product.

Lack of gallon markings
I bought this carboy to replace another that I had been using for about 4 years. This particular one certainly looks nice and has a wide mouth but not quite as wide as the one I had before. There are actually three major differences in this plastic carboy compared to my other one. First the thickness of the plastic is less and hence this new one doesn't feel as sturdy. Second, there are very limited markings for the amount in the carboy and the ones it has are very difficult to read. Third, the top is a little difficult to screw on straight and definitely needs the large O ring. I bought a 2nd top without a airlock hole but it doesn't come with its own O ring. I use this lid when I'm sanitizing the carboy. I had to place my own gallon markings on the outside of the carboy. So while it will definitely work one will definitely need to purchase the carrying straps to move it around.

One of the best fermentors I have ever used
Tight seal for the drain Spicket and it cleans up well even after the darkest stout :-)

Solid fermenter for the price and great for anyone who wants a port, doesn't want to deal with glass and is not ready to invest in stainless steel.
No problems real with this fermenter. Works as expected and no leaks through the port. The o ring in the lid is a little difficult to install and the pet material is a little flimsy.
