The Fermenator™ is the only weld-free interior fermentor on the market! Everything that touches your beer is heavy-gauge stainless steel or FDA-approved silicone. Our optimized design, identical to hydraulic systems under thousands of PSI, is also guaranteed to be 100% leak-free. Even the lid seal can be fully immersed under pressure! Weld-free fittings give you the peace of mind that comes with clean, bacteria-free beer.
