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!

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.

Love it

Needed a fermenting container for wine making that was at least 2 gallons - this one is perfect. Make sure you add the rubber stopper when you purchase if you need one for your air lock. I didn’t realize I needed it and ended up having to order one separately later.

Other reviews mention thin plastic housing but that doesn't bother me. Wide mouth makes for easy rinsing and cleaning and dry hoping and adjuncting. Great fit for my two gallon batches.
