Carboys are great, but they have some issues: They require funnels to get liquid in, and cleaning brushes to clean up after. They hold a decent volume, but all are a bit undersized for fermentation, and have no inherent measuring system. Glass Carboys are breakable, while plastic carboys scratch with the first brush cleaning. The Fermonster leaves all these problems behind, and still sells for less than $30.
These Fermonster Plastic Carboy Fermenters are made from heavy PET plastic, the same used in 2 L soda bottles, which is nearly impermeable to oxygen penetration. The smooth ribless walls are a feature that reduces yeast and sediment buildup, and imbedded are volume markers at five, six, and 7 gallons. The huge 4" opening makes filling a breeze, and cleanup is as easy as wiping down the inside. The 7 gallon is a monster of a fermenter, reducing blowoff issues seen with standard carboys. Glass carboys are fragile, and this is nothing like that. The hefty plastic construction will hold up to brew day abuse; and while movement is manageable, these can be upgraded with our Carboy Carrier.
These fermentors are completely air-tight; the bodies constructed of heavy, oxygen impervious P.E.T. plastic, 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.
