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

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

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

  • The initial concentration in the fermentor after pitching
  • The state of cell growth; this can have an adverse effect on the quality of the final product.  High rates of cell growth can also result in foaming and loss of product
  • A target peak cell concentration; this value might be used to initiate cooling or a transfer over to other vessels
  • The progress of the flocculation of yeast after chilling

The probe can be installed either directly into the side wall of the  cylindraconical vessel above the cone or in a pumped pipe loop that circulates the vessels contents.  The output of the vessel will relate to the volume of biomass present around the probe and can be calibrated to any desirable units of measurement, but commonly in cells/ml.  The signal is then fed into a suitable data logging system and that data can then be profiled for any given fermentation.
