As an essential material used in brewing, yeast plays a crucial role in the beer fermentation process. As the sugars in the wort are converted into alcohol, this interaction influences the taste, flavor, color, and of course, alcohol content of the  beer. Different yeast strains makes the characteristics of each beer different and unique. This is why an efficient yeast management and propagation system saves breweries a lot of time and money. The design and sterile manufacturing condition of the YoLong Brewtech Yeast Propagation makes it much easier for handling and introducing yeast into the system.

YoLong Brew Tech Yeast Prop System

YoLong Yeast Prop System

YoLong Yeast Prop System

When your brewery has a highly effective yeast culture and operation system, with the emphasis on safety and maximum utility, the yeast propagation system can be used to control yeast technology to your specifications.

Our Yeast Propagation Plant includes:

  • Tanks for yeast propagation/integration of wort
  • Air and CIP pipe
  • Semi-automatic control system (for microbrewery, brewpub and regional brewery)


Laboratory Propagation → Wort sterilization (steam) → Wort aeration (compressed air) → Yeast Pitching (Carlsberg Flask) → Yeast Reproduction and Propagation → Transfer to Fermentation Tank → Drain/recycle w/ Yeast Brink

YoLong Yeast Brink

Our Yeast Brink Systems can be used to wash, propagate, aerate, and grow pitches. Construction includes manways situated at the top of every tank to facilitate the addition of second pitches, solid nutrients, or introduce a quality-control sample probe. A glycol-cooled yeast brink has the advantage over other types of collection vessels because the agitated glycol offers better temperature control, in addition to easier yeast washing and sampling.

The main difference between a yeast propagator and yeast brink is that a yeast propagator has variable temperature setting controls and a yeast brink is simply a cold storage vessel as its purpose is to be used for yeast harvesting, pitching, and storage. Harvesting and re-pitching your yeast is a widespread brewery practice to spread the costs of the yeast culture over more batches (only possible when using the best harvesting and storage equipment and practices).
