6 Gallon FerMonster™ PET Fermenter – Extra Thick, Made in Canada

The 6 Gallon FerMonster™ PET Fermenter is now stronger and thicker, featuring 5% thicker walls for improved oxygen resistance, durability, and long-term performance. Designed for serious winemakers, homebrewers, and kombucha makers, this fermenter offers the convenience of PET plastic with performance approaching glass — without the risk.

Made from 100% virgin, food-grade PET plastic, the FerMonster™ contains no plasticizers, is BPA-free, and is completely taste- and odour-free. Its smooth, rib-free interior prevents yeast and sediment from sticking, making cleaning fast and easy.

The wide 4” mouth allows easy access for cleaning, dry hopping, fruit additions, and infusions. Each unit includes an air-tight, one-piece lid with O-ring and a pre-drilled hole designed to accept a #10 stopper.
(Lid hole diameter: 4.3 cm / 1.7”)

Graduated markings for 5, 6, and 7 gallons are molded into the side for easy volume tracking. The FerMonster™ is large enough to be used as both a primary or secondary fermenter, and its thick PET construction provides an excellent oxygen barrier for aging and storage.
