FerMonster™ PET Fermenter


With a wider 4” mouth, there is easier access for cleaning. It is made of heavy P.E.T. plastic.
  • Our Carboys do not use any plasticizer and are made with 100% Virgin material. Made with Food grade materials and BPA free.
  • Comes with an O-ring and air-tight ONE PIECE lid with a hole that will take our #10 stopper. The lid hole is 4.3 cms (1.7”) in diameter.
  • There are no ribs, only smooth sides, so no yeast or sediment will adhere to walls during fermentation.
  • Solid lid is available as an option (not included in the product sold as a separate item) so you can customize your lid (drill as many holes as you wish).
  • Completely taste and odour-free. It is also stain resistant.
  • Impermeable to oxygen.
  • 100% made in Canada.
  • Comes with 5-Gallon, 6-Gallon and 7-Gallon easy-to-read markings on the side.
  • Also they are big enough so you can use them as your Primary Fermenter.
  • Our FerMonsters™ are also ideal for making Kombucha as they can withstand Kombucha PH levels concentration. Be sure not to add any liquid hotter than 53ºC (127ºF), DO not steep tea on them if liquid is hotter than those temperatures
  • A great addition to your FerMonsters™ are our FerMonster™ Strainers, MonsterMesh and MiniMesh. They will allow you to reduce the head space if required filling it up with glass marbles or any food grade element that you consider appropriate. They will help you infuse your wine/beer and handle all infusions. They fit all of our FerMonsters™.

NOTE:We do not recommend that you drill a hole on the PET Carboys or FerMonsters™, as this must be done with the right equipment and right expertise. Doing this may crack your carboy and become unusable.

NOTE: The FerMonster™ PET Fermenter is hard to carry, we strongly suggest that you purchase our carboy carrier (make sure it fits your specific size of carboy).
