Complete Multi-Port Yeast Brink - 1/2BBL Keg for Yeast Propagation

Professional Yeast Management in a 1/2 BBL Format

Harvesting, storing, and repitching healthy yeast slurry requires an aseptic environment and reliable pressure control. This complete multi-port yeast brink is built on a heavy-duty 1/2 BBL (15.5 gallon) stainless steel keg body, configured specifically for cellaring operations. It gives you a dedicated, closed-loop vessel to crop yeast directly from your conical fermenters, hold it under cold head pressure, and pitch into your next batch without exposing the slurry to ambient air or contaminants.

Closed-System Yeast Transfers and Storage

Exposing yeast to oxygen between batches compromises cell viability and introduces infection risks. With integrated sanitary tri-clamp ports, this brink allows you to run closed-system transfers from the fermenter cone straight into the keg using standard TC brewing hoses. Once filled, you can hook up your CO2 supply to maintain a protective blanket and preserve viability in your cold room. When brew day arrives, you can pitch the yeast by simply pushing it into the fermenter with top pressure, eliminating the need to haul open buckets or rely on external transfer pumps.

Sanitary Tri-Clamp Ports, Valves, and Gauges

The top dome features dedicated tri-clamp ports configured for gas inlet, pressure relief, and monitoring. An integrated pressure gauge lets you verify head pressure at a glance, while the pressure relief valve protects the vessel against over-pressurization during collection. The bottom port setup allows smooth draining and pitching of dense slurries without clogging. Because every connection uses standard sanitary tri-clamp sizing, you can break down the hardware quickly for thorough cleaning, inspection, and standard clean-in-place (CIP) cycling.

Durable Stainless Construction

Built from thick-gauge 304 stainless steel, this brink handles routine commercial brewery washdown cycles, hot caustic, and acid sanitizers without pitting or corroding. Welded chimes at the top and bottom protect the valve assembly during handling and make transport between the cellar and cold storage secure and straightforward.
