Finally a Wide Mouth PET Carboy that it is easy to clean and has a lid with an O-ring that seals air tight! You've heard all about the problems with those bubblers, thin plastic, lids that don't seal, and difficult to clean because of all the little bubbles. Those days are over with the Fermonster Wide Mouth PET Carboy.
Brilliantly clear with built-in 5-Gallon and 6-Gallon markers on the side for your convenience. Note: Fermonster XL has a built-in 7 gallon marker. The 4" wide mouth opening and rib-less side make mixing and cleaning a breeze. **Requires a #10 stopper or medium bung** (#774 or #775).
I really like the wide mouth. Makes it easy to clean and add additions to the fermenter. I haven't had any problems with air leaks. Works great!
