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're 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.

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.

Looks like a great option for fermenting 2 or 2.5 gal stove top BIAB, or spitting 5 gal batches for experiments.

Split batching. Plastic wide mouth fermenters for primary and secondary are the way to go.

I have 6.5 gallon fermenters and I want to brew smaller batches to brew more types of beer more often without having as much beer to store after bottled

What setup for a blow off would I use with this 3 gallon fermonster?
Zachary Amarante on Jul 21, 2019
BEST ANSWER: If you have a 3-piece airlock, you can just remove the cap and inner piece and add the blowoff tube to the center

Leaked and oxidized 2 batches of beer... Returned.
I originally had the larger size and bought these to do small 2-2.5g trial batches. The larger containers, did nothing but leak air out the top, the spigot worked great for transfers, but if u have oxidized beer, that really doesn't matter.

Response from MoreFlavor
Thank you for the review! We're sorry to hear about the leak, no one wants oxidized beer. Was the leak coming from the airlock and stopper area or down from the threads? The lid o-rings can be tricky to seat so if not done properly, you won't have an airtight seal.

Does the job
I bought 2 of these for split batch secondary to eliminate large headspace and the occasional small experimental batch. I had some issues getting the spigots to seal, but I did get them to seal. It's really nice to be able to draw a small sample without pulling the lid off; just give it a little burp of CO2 from the top and draw the sample. Overall, they get the job done for being inexpensive PET carboys.
