The problem addressed by the present invention is to provide a method that is for producing a non-alcoholic beer-flavored malt beverage and that achieves a low ethanol concentration of less than 0.005 vol% even in the case that fermentation is performed for approximately 3-20 days at a temperature of approximately 3-7°C. The solution to the problem is a method that is for producing a non-alcoholic beer-flavored malt beverage and that includes: a step for adding yeast to a wort having a Brix value of 15-50; and a step for fermenting the wort to which the yeast has been added.
