Beer Filtration
Beer filtration is normally carried out in 2 basic stages with first the production of a bright beer and second the production of sterile beer (if this is required).
Production of Bright Beer
A bright beer looks clear and the major amount of the yeast and suspended solids has been removed. It is likely to contain a small amount of yeast and will not be sterile.
For this filtration there are two types of beer filter for the brewer to consider:
- D.E. (or kieselguhr) pressure filters using D.E. powder as a filter aid
- Sheet filtration using coarse/medium grade filter sheets
We recommed that Sheet Filtration is used for brews up to 1000 litres (10 hl/6 UK barrels) and that DE filtration is used for 1000 litres upwards.
Production of Sterile Beer
Once Bright Beer has been prepared this can be sterile filtered through a multi-stage cartridge filter system comprising a range of different porosity filters.
See our pages on DE Filters and on Sheet Filters.
