Protect fermenting beer from harmful UV exposure with the Cover for The Catalyst Fermentation System, a custom-fit fermenter cover designed specifically for the Craft a Brew Catalyst conical fermenter. Made from durable 600D vinyl laminated canvas, this brewing cover blocks 100% of UV light to help prevent light strike and skunky off-flavors during fermentation. The tailored design hugs the contour of the Catalyst tank while still allowing brewers to access volume markers and monitor fermentation progress through an integrated viewing flap.

Integrated carrying straps with reinforced stitching help simplify moving the fermenter, whether lifting the tank from the stand or transporting the entire assembled system. Additional securing straps help stabilize the cover during movement and storage.

Designed specifically for compatibility with The Catalyst Fermentation System, this protective cover can also be modified to accommodate the Catalyst ball valve configuration. The durable construction supports repeated use in active brewing environments.

Widely used by homebrewers seeking improved fermentation protection and mobility, the Cover for The Catalyst Fermentation System helps maintain better brewing conditions while protecting beer from damaging light exposure.
