16oz Mason Jar


A Kerr wide mouth mason jar is compatible with The Catalyst Fermentation System. Wide mouth mason jars are useful homebrewing tools - perfect for making yeast starters, serving beer or making tinctures. Read our blog for tips on making and using tinctures to flavor your homebrewed beer.

This 16 oz Kerr wide mouth mason jar is an exact replacement for the jar that comes with The Catalyst Fermentation System. The Catalyst features a butterfly valve compatible with wide mouth mason jars. Sediment and yeast collect in a removable jar so you don't have to use a siphon to transfer your beer. 

*This jar does not include a lid (seal or ring).
