Abstract
The published information concerning non-biological beer haze has been surveyed, and what are considered the outstanding facts from papers which have appeared since 1911 are presented under the following headings: (a) measurement of haze; (b) chemical composition and physical properties of the haze material; (c) a comparison of chill haze and permanent haze; (d) beer composition in relation to haze constituents; (e) analytical investigations of beer constituents which may contribute to haze; (f) prediction of shelf life; and (g) control of stability in production brewing.
