The Catalyst fermenter is an elegant piece of brewing equipment through which they've simplified the process of fermentation, making it easier than ever to brew great beer at home.

  • Conical tank with 45˚angle 
  • Silicone gasket with multi-surface contact to ensure a perfect seal 
  • 6.5 gallon capacity 
  • Includes a proprietary 3" butterfly valve. The largest in the industry. 
  • All steps in one vessel: Primary, Secondary, Harvest Yeast and Bottling 
  • Strong and durable stand, designed with I-Beam and honeycomb structure. 
  • The Trub Trap is compatible with any wide mouth jar to eliminate transfers.
  • Assembled unit is 26.25" tall (without airlock), and is 17" wide

The Trub Trap consists of a 3" butterfly valve and is compatible with any wide mouth mason jar so you can remove kettle trub and fermentation trub, pitch a yeast starter, harvest yeast and bottle without disturbing or oxidizing that precious beer.


Use a 24 oz. mason jar to catch trub, hops and other pre-fermentation sediment, then discard it by closing the valve and unscrewing the mason jar.


Use a 16 oz. mason jar as a yeast starter, attach and open the valve to pitch. Leave the jar attached to collect all of the primary fermentation trub.


Use an 8 oz. mason jar during secondary to catch all of your viable yeast and refrigerate for later use.


The Catalyst's tank is made from Tritan®, a medical-grade, BPA-free, polymer. This food-safe polymer is the highest quality used in a fermenter, providing the clarity of glass with the durability and convenience of plastic. This material acts as an excellent barrier against oxygen, making our tank 93% more scratch-resistant than other plastic fermenters. It is dishwasher safe and withstands temperatures of up to 230º Fahrenheit.
