The EBC Manuals of Good Practice are being revamped! After consultations within both the EBC and the wider network of brewers, the decision was made to start a process of reviewing the outdated manuals. The manual Beer Filtration and Stabilisation is now in print in its completely revised form, in terms of both its content and its look and feel. Technically, there have been a lot of developments in beer filtration.

With the arrival of affordable membrane technology, the need for an assessment and inclusion into the manual became an important goal, as did the need for a thorough overhaul of the existing chapters on depth filtration in its many forms (kieselguhr, perlite, cellulose, and others). Beer Filtration and Stabilisation represents a most valuable addition to the current state of knowledge and practical applications for filtration technologists, process engineers, and brewers operating in the beer production environment.
