Kettle Trub (Pre-Fermentation)

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.

Yeast Starter & Primary

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.

Secondary & Yeast Harvesting

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

Innovative Materials

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.
