Colloidal Beer Stability for Optimum Shelf Life


Today consumers expect a beer with a long shelf life free of changes in clarity and appearance. Colloidal stability, in addition to microbial stability, is the main influencing quality criteria for a sufficient shelf life of packaged beer.


The newly developed Pall CBS (Continuous Beer Stabilization) system is a flexible polyphenol stabilization solution for batch and continuous operation, providing precise stabilization effectiveness combined with reliable colloidal beer stability at the lowest cost and negligible beer losses.

Why is beer stabilization important?


When it comes to beer shelf life, brewers seek to affect the product as little as possible and only as much as necessary. This new CBS technology provides the perfect balance between optimum  colloidal beer stability with minimum change in beer  composition.


Pall’s Continuous Beer Stabilization (CBS) System combines proven materials for beer stabilization (PVPP) with a new technology, enabling continuous stabilization of all kinds of beer. The latest development with CBS is the beer IoT based digitalization which allows a more advanced process control and optimization.


During the beer stabilization process, precise polyphenol reduction and beer stability is assured by varying the flow through the individual columns, utilizing maximum PVPP adsorber efficiency.


The compact design with a throughput/volume ratio of 15:1 results in  rapid switching between brands and significantly reduces beer and beer extract  losses.

Oxygen pick up is minimal from the start due to the compact design and seamless switch between de-aerated water and beer at the process start, end and brand changes.


The CBS system is designed compactly to occupy a smaller footprint, requires low investment cost and improves operational costs. The small system  hold up lowers chemical, water, and energy consumption and eliminates the need for CIP tanks.The CBS System covers a production range between  100 to 900 hl/h and is designed to provide flexible handling of varying stabilization.


IoT in the brewing process - Impact on Performance and Consumption

The implementation of IoT in the beer-making process supports transforming the industry towards sustainable and cost-effective production. With IoT based digitalization in filtration and stabilization, breweries can optimize processes, automate machine learning, and manage data for reporting, traceability, and analysis.


But IoT users have one primary concern in common – data security. Pall values data security as the highest priority and proactively takes all the necessary steps to remain best-in-class. Therefore, it is essential that the latest state-of-the-art technology protects brewery data with penetration tests and code scanning exercises to continuously identify risks and takes the necessary actions to ensure brewery data remains where it’s needed.


Through Pall BeerIoT, brewers can optimize their operations, improve sustainability and quality initiatives, and improve their OpEx.

CBS IoT To gain maximum advantage from the data generated by a CBS control system Pall implemented IoT-based real-time data management with constant access to valuable information across the organization in user-defined formats. The ability to benchmark against other installations within a brewery group and against the industry average is also available.
Examples of digital data analytics
  • Specific consumption data: water, cleaning agents, electricity, membranes 
  • Performance data: degree of utilization, efficiency, and downtimes
  • Quality data: oxygen uptake, color, original extract and haze
  • Notifications, alarms and messages
Documentation and service data Pall IoT provides direct online availability of all system-specific documentation and training documents, spare parts lists, service reports, operating instructions, safety instructions and acceptance reports.
