This stainless steel conical fermentor features a weld-free interior, a dump valve for removing yeast and sediment, and a rotating racking arm for transferring. Prior to bottling or kegging, you can dump your yeast and trub out of the bottom, making for a very clean transfer. This helps with a cleaner, crisper beer everytime! The lid has a removable soda keg-style hatch that is pressure capable, allowing you to easily transfer using CO2 to minimize air exposure. Optional casters and leg extensions are available as well. The 7 Gallon Fermenator is designed to ferment 5 gallons at a time.
