PROBLEM TO BE SOLVED: To provide a method for producing a distilled liquor abundantly containing vanillin and having a good flavor. SOLUTION: This method for producing the distilled liquor comprises regulating pH of an unrefined liquor just before distillation to <=3.8 and then distilling a vapor produced from the unrefined liquor in the presence of copper and/or a compound containing the copper. Examples of the distilled liquor include Shochu (low-class distilled spirit), spirits, whiskey, brandy, etc. Examples of the copper compound include oxides and slats. The resultant distillate liquid may be stored in the presence of a compound containing any of Ca, K, Mg and Na. Thereby, the resultant distilled liquor abundantly containing the vanillin and having a splendid and sweet fragrance and mellowness or an aged feeling imparted thereto can readily be obtained. |
