Yeast Propagation Management for Breweries
Yeast is the most important component in beer production; its properties have a decisive influence on the quality, flavor and filterability of the beer.
For ideal yeast propagation – and thus for a good beer – hygienic plant design is essential. Yeast quality is defined particularly by the preservation of yeast viability and by optimized yeast vitality. GEA offers everything for comprehensive yeast management.

The intelligent combination of a frequency-controlled pump and a controlled overflow valve allows the compensation of variations in yeast consistency and wort flow rate
The method GEA developed to determine the yeast cell count through differential turbidity measurement ensures accurate yeast pitching. Variations in the basic turbidity of the wort are compensated for. A static mixer developed especially for this application provides proper mixing of the yeast into the wort. As an alternative to differential turbidity measurement, the yeast volume can also be determined by a viable cell count.
> 0.5 bar above the CO² saturation pressure
> 0.5 bar under the wort pressure at the dosing
What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
The 2022 CO2 shortage forced breweries to review their dependency on global supply chains. Many were forced to close, unable to carbonate their products. At its breweries in Germany, OeTTINGER GETRÄNKE is turning its own CO2 into a powerful lever for independence and sustainability – with the help of CO2 recovery technology from GEA.
