Effective yeast management

The importance of yeast management in a brewery cannot be overstated. Chris Boulton and David Quain rightly put it when they said, “If I was a yeast cell I would want to be looked after, cherished even!”. Understanding how many live yeast cells are working for you is one of the most important facets of yeast management. Better yeast management can directly lead to more consistent fermentations and beer quality, reduced fermentation times, reduced production of off-flavours, financial benefits etc.

ABER Instruments has over 25 years of dedicated experience in providing brewing equipment that measure the live concentration of yeast in the brewing process. ABER yeast monitors are used and trusted by all the major brewing groups across the world. We also have a host of scientific publications that attest the benefits of the technology and the reliability of our brewing equipment

The ABER Yeast Monitors can be useful for the
following core applications in a brewery

Automatic fermentation monitoring

How it works

Many of the world’s leading brewing companies now understand the benefits of producing a yeast growth profile over the entire propagation period from start to finish.  We can recommend the best Compact Yeast Monitor set-up optimised for this operation. 

The data from the Yeast Monitor can be used to determine:

  • The initial concentration in the propagator after pitching
  • The rate of cell growth in the propagator; this will pick up an early indication if the yeast cells are growing at the correct rate or if the propagation has become “stuck” due to underpitching or poor quality seed.
  • A target peak cell concentration; this value is usually the most important one as propagation might be stopped at a certain critical concentration or the final value might be used to calculate the dosing volume into a full production vessel.

The probe can be installed either directly into the side wall of the propagator if there is an appropriate fitting (25mm Ingold will be ideal).  It can also be installed in a pumped pipe loop that circulates the vessels contents.  In most cases we recommend the Compact Adapt Yeast Monitor as this is designed to be used in a side wall fitting.
