Product details

Perfect for 2-3 gallon batches of beer, wine, cider, and mead! The FerMonster™ 3 Gallon Fermenter provides advantages over narrow mouth carboys. The 4" wide mouth makes the fermenter easy to clean, dry hop or infuse. Made from P.E.T plastic, the ribless design ensures that yeast and sediment fall to the bottom after fermentation. The lid o-ring makes the vessel air-tight to keep out oxygen and reassure that your airlock will bubble away without any unwanted seal leaks. 

Siphonless version also available making transfers super easy. Siphonless works great for large batches of kombucha!

Does the job - very thin.

Size is great, but the material is super thin, so plan on moving the fermenter very little and plan on having some issues if you don't buy their lid opener tool. Walls so thin that you can't hug the fermenter to get the lid off. Both containers came dented but I kept them. Paid the price but I'd buy something made of glass in future. Plus the thin walls makes brew more susceptible to outside temp changes whereas glass will insulate. I should have taken heed to other reviews about flimsy material but i didn't and here I am parroting what they said before me. Other than that.....making cider and perrry with ease.

Not Bad

The 3 gallon Fermonsters were as expected. I bought O-rings to help create a seal for the tops, which were default with the fermenters. They were a typical rounded o-ring. I think a flat o-ring would be easier to manage.

Overall nice and as expected

Easy Fermenting!

The FerMonster is my new favorite fermenter! It makes making larger batches easy! The walls are a little flimsy like other reviewers mentioned but it doesn’t bother me, as long as you’re aware of it you will adjust accordingly. The top seals great as well. I’m very happy with these.

Great size, I brew 5 gallon batches and have 2 1/2 gallon kegs. Allows me to keg 1/2 the batch and condition the other half in the Fermonster.
