The diagrams and arguments in this paper summarize the reasons which led to the conclusion that the Brand and Iodine scales are misleading in any particular brewery, as their readings are not proportional to beer colour, and that they are still more misleading in comparisons of colour results between different breweries, since a dark beer may appear to measure up to three times as much in one brewery as in another; moreover, the standards are not permanent. Consequently, it seems highly desirable to accept the Analysis Committee's recommendation that the E.B.C. scale of coloured glasses should be adopted, as tests by the Committee have shown this series to be free from the defects found in the Brand and Iodine scales. It has been arranged that this and the other methods given in the E.B.C. Recommended Methods of Analysis for Barley and Malts should be adopted on the Continent of Europe from 1st October, 1953. British readers will note that the method and standards for colour measurement in Britain and on the Continent will then be identical. It is, however, still necessary to allow for the fact that the Continental standard mash has a concentration 1·18 times that of the British standard mash.
