PROBLEM TO BE SOLVED: To provide a beer-taste beverage having an excellent kokumi, a method for producing a beer-taste beverage having an enhanced kokumi, a method for enhancing the kokumi of a beer-taste beverage, and a kokumi enhancer for a beer-taste beverage. SOLUTION: A beer-taste beverage having a content of free amino nitrogen (FAN) of 30 ppm or more and a content of wheat-derived protein having a molecular weight of 35 to 50 kDa of 20 ppm or more. Preferably, the content of FAN is 90 ppm or more. In addition, a method for producing a beer-taste beverage having a step of increasing the content of a wheat-derived protein having a molecular weight of 35 to 50 kDa, and a kokumi of a beer-taste beverage having a step of increasing the content of a wheat-derived protein having a molecular weight of 35 to 50 kDa. How to enhance.
