Summary
The most widely used filter aids in brewing are a refined diatomaceous earth, polyvinylpolypyrrolidone, and silica gel. Diatomaceous earth is shipped in bags or, less commonly, in bulk, and its physical properties approach those of a flour or powder. This method presents the basic procedures for obtaining representative samples of filter aids shipped in bags or in bulk and preparing them for laboratory analysis.
