A colorimetric method for the estimation of the alcohol content of beers has been adapted for automatic operation; it involves treatment with hexanitratocerate after oxidation and dialysis to remove interfering carbohydrates. It has been found possible to eliminate the distillation stage, while retaining a satisfactory degree of accuracy; the time for the passage of one sample through the apparatus is 8–9 min.
