(57) [Summary] [PROBLEMS] To provide a method for producing distilled liquor by improving the conventional heating distillation and obtaining distilled liquor with rich flavor in good yield. [Structure] A method for producing distilled liquor, which comprises a treatment of ultrasonic treatment in the distillation step in a method for producing distilled liquor obtained by ordinary heating distillation. The ultrasonic treatment is preferably performed when steam is generated during heating in a distillation can and / or when steam is condensed in a condenser, that is, for fermentation mash, liquid or steam. [Effect] It is possible to obtain high-quality distilled liquor with a deep flavor and an excellent balance of flavors, and shorten the distillation time. The condensation efficiency can be improved. |
