Plastic conical fermenters are a great option for brewers that want to all the advantages of a conical fermenter without the price tag of a full blown stainless steel unit. All of our plastic conicals will enable you to dump trub and harvest yeast. The FermZilla and Catalyst have the added advantage of using a clear plastic material that allow you to visually track your fermentation's progress. If space is a concern, the 7.9 gallon FastFerment comes with mounting hardware so you can hang it on your wall, a uniqe and convenient feature that keeps the fermenter off the floor and at the percise height you want it, without the need for different sized stands. If you're looking to ferment under pressure or do pressure transfers from fermenter to keg, we highly recommend the FermZilla, which is pressure rated to 35 psi.
