A method by which the ability of untreated barley to cause early flocculation, i.e., whether or not a factor causing the early flocculation of yeast is present in untreated barley, can be judged much more easily in a shortened period as compared with the methods of the prior art. Specifically, a method for judging the ability of untreated barley to cause early flocculation by the fermentation test using yeast, which comprises adding an enzyme to the barley to conduct the enzymatic treatment of the barley, adding the product of the enzymatic treatment or a high-molecular fraction separated from the product to a synthetic wort to prepare a sample for the fermentation test, subjecting the sample to the fermentation test, and determining the turbidity of the sample after 48 hours for judging whether or not such a factor is present in the barley. |
