System of the present invention provides the manufacturing method that one kind can inhibit the acidic beverages containing carbonic acid for having spore genus lactubacillus bacterium (Sporolactobacillus) proliferation and the acid alcohol beverage containing carbonic acid in sterilization processing before not implementing. What adds lactic acid and arbitrarily adds ethyl alcohol in the acidic beverages containing carbonic acid, so that the relationship of lactic acid content and ethanol content meets following formula: formula CL≧-0.02xCE+ 0.08, CL gt； 0,CE≧0(CL: lactic acid content (quality %), CE: ethyl alcohol (degree)), and pH value is adjusted to 2.7 ~ 4.5.本發明係提供一種可在不實施前殺菌處理之情形下抑制有孢子乳酸菌屬細菌(Sporolactobacillus)增殖之含碳酸之酸性飲料以及含碳酸之酸性酒精飲料的製造方法。於含碳酸之酸性飲料中添加乳酸以及任意地添加乙醇，以使乳酸含量與乙醇含量的關係滿足下述式：式CL≧－0.02xCE＋0.08、CL>；0、CE≧0(CL：乳酸含量(質量%)、CE：乙醇(度數))，以及將pH值調整為2.7~4.5。
