The FermZilla Flat Bottom Fermenter is an excellent option for making all kinds of beverages, from beer and wine to kombucha and cold brew coffee. It’s compact, lightweight, and made of brilliantly smooth PET. The extra-large lid opening makes it easy to get your arm inside and scrub the walls clean after use. The Flat Bottom features the same lid as the Conical FermZilla’s, so installing accessories like a thermowell or Temp Twister Cooling Coil couldn’t be easier.
