Beer filtration is inherently a balancing act. Precoat filtration
technology is the mostly widespread method of filtration. It has been
developed in the last decades more and more into a highly efficient
filtration technology. Filtration must be tight enough to remove these
unwanted components without losing the essential quality of the beer
being filtered. This article discusses the removal of haze particles,
haze-producing substances, and organisms. Furthermore, the technological
influences on filterability and fluid dynamics basics are shown. With
that knowledge the article describes easy ways for craft brewers to
improve the filtration process.
