Beer Recovery: Maximizing Efficiency and Yield in Commercial Breweries
As breweries face increasing pressure from rising raw material and energy costs, yeast recovery has become a key strategy for improving sustainability and profitability. By reclaiming valuable beer extract from surplus yeast, breweries can significantly reduce waste and enhance production efficiency.
What Is Beer Recovery?
Beer recovery is the process of extracting residual beer from excess yeast generated during fermentation. This recovered beer can be safely blended back into the final product—up to 5% by volume—without compromising taste or quality. It’s a cost-effective, sustainable solution that helps breweries get more from every batch.
The Keraflux® Beer Recovery System
Pall’s Keraflux® platform is a state-of-the-art solution for yeast recovery in commercial breweries. Designed for high-solid bioproduct streams, it features:
- Exekia® ceramic membranes for high-efficiency crossflow filtration
- A frequency-controlled loop pump with integrated cooling
- A CIP (Clean-in-Place) unit for easy maintenance
- A control cabinet with real-time monitoring and process control
This modular, plug-and-play system is ideal for breweries looking to scale up beer recovery operations with minimal downtime.
Cost Reduction by Process Control
The process for yeast extract recovery uses a ceramic cross flow technology with specific control features to achieve reduced costs. The below table describes the benefits of this process:

Long Production Cycles and Less Cleaning Cycle |
Continuous adjustment of the process parameters to variable set points minimize energy consumption and provide gentle treatment of the yeast during the entire process. |
Yield, Energy Consumption and Performance Improvements | The beer recovery is conducted in a batch process, which offers several advantages:
|
Quality Enhancement | To evaluate the percentage of beer which can be blended back to production without compromising the beer quality, several test were conducted. By chemical and sensory analysis carried out by independent institutes, it was shown that a back blending ratio of up to 5 % volume is suitable. The superior quality of the recovered and blended beers has been confirmed as follows:
- Closed system for minimum oxygen uptake - Clear cut off with low turbidity and almost yeast free beer
|
Quality and Safety in Beer Recovery
Independent testing confirms that beer recovery does not compromise product quality. Key findings include:
- No detectable difference in taste by expert panels
- No significant changes in esters, fatty acids, or flavor compounds
- Low turbidity and minimal yeast presence
- High microbiological safety with hot water sterilization up to 90°C (194°F)
Membralox® IC Ceramic Filtration Modules
For breweries seeking even greater efficiency, Membralox® IC ceramic membranes offer:
- Up to 45% more filtration capacity than standard modules
- Compact system design with a smaller footprint
- Reduced water and chemical usage during cleaning
- Long service life and exceptional chemical resistance
These membranes are ideal for high-volume beer recovery applications and are 100% ceramic and bubble-point tested.
Fast ROI and Scalable Solutions
With a return on investment in just 1–2 years, yeast recovery systems like Keraflux and Membralox IC are a smart investment for breweries of all sizes. Systems are available in multiple configurations to meet specific production needs. Implementing a robust beer recovery system not only improves operational efficiency but also supports sustainability goals. Whether you're a craft brewer or a large-scale producer, beer recovery is a proven strategy for maximizing yield and minimizing waste.
