The Catalyst Fermentation System (6.5 Gallons) brilliantly saves time by skipping steps allowing you to bottle straight from your fermenter.  This innovative piece of homebrewing equipment simplifies the fermentation process, making it easier than ever to make great beer at home.

Why Use The Catalyst?

The Catalyst has efficiently combined four steps into one: Primary, Secondary, Yeast Harvesting, and Bottling. Using the patented Trub TrapTM and the included wide mouth mason jar, you can expertly dump pre-fermentation and post fermentation trub, as well as harvest yeast for future batches. From there, you can install the bottling attachment, allowing you to bottle straight from the fermenter. No more need to transfer!

This fermenter is made out of Tritan™, a food safe, BPA-free polymer. This material has the clarity of a glass fermenter, but also is resistant to shattering. It is also 93% more scratch resistant than standard plastic PET Fermenters used in homebrewing. The Catalyst and removable silicone gasket also dishwasher safe, which makes cleanup super easy.
