8 Oz. Mason Jar (Yeast Catch)

Collect and store harvested yeast with the Craft a Brew 8 Oz. Mason Jar (Yeast Catch), a wide mouth mason jar designed for use with The Catalyst Fermentation System and other homebrewing applications. This reusable 8 oz glass jar connects directly to The Catalyst’s butterfly valve system, allowing brewers to collect viable yeast during fermentation with minimal disturbance to the finished beer. The compact size helps reduce product loss while providing convenient yeast storage for future batches.

Designed specifically for yeast harvesting, this mason jar is commonly used during secondary fermentation after initial sediment removal. Brewers can replace larger trub collection jars with this smaller vessel to capture cleaner yeast for reuse in future beer fermentations.

The included lid and sealing ring allow harvested yeast to be stored in the refrigerator until needed for another batch. In addition to yeast collection, the jar can also be used for tinctures, ingredient storage, and other fermentation-related projects.

Widely used by Catalyst owners and homebrewers interested in yeast harvesting, the Craft a Brew 8 Oz. Mason Jar provides a practical and reusable solution for cleaner yeast collection and storage.
