The malting behaviour of fifteen barley varieties widely grown between 1880 and 1980 has been compared using material grown at two sites in England in 1980. All the varieties examined were considered to be of malting quality at their time of widespread commercial use. Varieties introduced after 1950 gave higher Hot Water Extracts (mean 74·7%) than varieties introduced before 1950 (mean 71·0%), and when the yield data were included to calculate the yield of extract/ha the post‐1950 varieties were found to exceed the older varieties by 48·7%. The Kolbach Index of the modern varieties was higher, although there was no evidence of an increase in cold water extract.
