A simple technique for determining the viscosity of extracts of small samples of barley grains is required for use in screening large numbers of selections in a breeding programme. Extraction of 2‐g samples of ground grain at pH 1.5 has proved satisfactory and the results of viscosity measurements of such extracts are compared with published information on β‐glucan contents and with maltsters' assessments of a number of barley varieties.
