The proteins/macromolecular constituents of unconcentrated/unfractionated beer and wine (50–75 μL) have been analyzed by high resolution two‐dimensional electrophoresis and silver staining. The beer patterns are dominated by up to four horizontal strings of spots of M r 34 000–43 000 and p I 5.0–7.0 which have been tentatively identified as proteins previously isolated in association with foam and haze formation. Reproducible qualitative and quantitative differences were detected in different commercial beers. Distinctive patterns were also obtained with the wines.
