"Integration of an ABER Yeast Monitor for yeast pitching guarantees and is a major part of, a consistent quality, improved fermentation performance, optimisation of cellar capacity and simpler operation. The ABER system is especially interesting if there is a demand for flexibility due to, various fermentor capacities, various wort qualties, various yeast strains, continuous production regimes and limited assistance by QA."
According to Mrs Elke Schuermeyer and Dr Andreas Ludwig from the Radeberger Gruppe Central Laboratory, "The Yeast Monitor requires minimal maintenance: a routine monthly check is made to compare the Yeast Monitor reading with the live cell concentration but the instrument settings are not changed. As a consequence, the Yeast Monitor is completely integrated into the process."

Brewers become more and more aware of the fact that a good yeast management is essential for a stable product. I’ve experienced the Aber systems (first as a user, now in sales) to be the most reliable and accurate systems for optimal yeast management.

Yeast pitching systems incorporating the Aber based system are described as the best that is currently available and capable of delivering a pitching rate that is plus or minus 5% of the desired value.

"In my opinion, Aber Yeast Monitors are the best way to reproducibly
pitch yeast into wort and so assure consistent fermentation and beer flavor"

"The Aber Biomass meter is the accepted benchmark for viable
yeast measurement in the brewing industry"
