FerMonster 7 Gallon Plastic Fermenter

The FerMonster 7 Gallon Plastic Fermenter is a lightweight, durable fermentation vessel designed to make fermenting, cleaning, and handling your beer easier. Its generous 7-gallon capacity provides ample headspace for typical 5-gallon batches, while the wide-mouth opening makes filling, cleaning, dry hopping, and transferring simple and convenient.

Wide-Mouth Design

Unlike traditional narrow-neck carboys, the FerMonster features a large opening that provides easy access to the interior. The wide-mouth design makes it easier to add ingredients such as fruit, hops, oak, and other additions while also allowing you to reach inside for thorough cleaning.

Lightweight PET Construction

The FerMonster is constructed from clear PET plastic, giving you excellent visibility of your fermentation without the weight and handling concerns associated with glass carboys. The transparent vessel makes it easy to monitor fermentation activity, yeast sediment, and clarification without opening the fermenter.

Ideal for 5-Gallon Batches

With a total capacity of approximately 7 gallons, the FerMonster is well suited for standard 5-gallon beer batches. The additional headspace helps accommodate krausen during active fermentation and reduces the likelihood of fermentation foam reaching the lid or airlock.

Easy to Clean

The smooth interior and wide opening simplify cleaning and sanitation between batches. Use a brewery-approved cleaner with a soft cloth or non-abrasive cleaning tool to help preserve the interior surface. Avoid abrasive brushes or pads that may scratch the PET plastic.
