8 Oz. Mason Jar (Yeast Catch)

After primary fermentation and trub removal, attach the 8 oz mason jar to The Catalyst butterfly valve system. Open the valve to collect yeast as it settles into the jar.

Once collected, close the valve, remove the jar, and seal with the included lid for refrigerated yeast storage until your next brew day.

• One 8 oz wide mouth mason jar
• Metal sealing lid
• Screw-top ring

This 8 oz mason jar is commonly used with The Catalyst Fermentation System for collecting viable yeast during fermentation.

Typical use includes:

• Removing larger trub collection jars after primary fermentation
• Installing the 8 oz jar for cleaner yeast collection
• Storing harvested yeast for future brewing batches

The smaller jar size can help reduce liquid loss during yeast harvesting.

In addition to yeast harvesting, this mason jar can also be used for:

• Small fermentation projects
• Brewing additives and flavor infusions

The wide mouth opening makes filling and cleaning easier.
