The subject of the present invention is to provide a method for producing a favorite beverage raw material extract that hardly causes a scale in a step of producing a favorite beverage raw material extract itself, and also hardly causes the scale in a step of producing a beverage packed in a container when the beverage packed in the container is prepared using a favorite beverage extract. To solve the problem, the method for producing a favorite beverage raw material extract includes the following steps (1) to (4): (1) extracting a favorite beverage raw material with water, and then subjecting the extracted raw material to solid-liquid separation to produce a water extraction solution； (2) subjecting the water extraction solution obtained in the step (1) to a phytic acid decomposing enzyme treatment to produce an enzyme-treated extraction solution； (3) bringing the enzyme-treated extraction solution obtained in the step (2) into contact with a positive ion exchange resin； and (4) subjecting the enzyme-treated solution that has been brought into contact with the positive ion exchange resin obtained in the step (3) to an insoluble substance removing treatment.
