Particularly, the caffeine content is 0-0.04 mass%, preferably 0-0.033 mass%, and the quercetin glycoside content is 0.005-0.2 mass%, preferably 0.02-0.2 mass% in the coffee beverage. The content ratio of quercetin glycoside to caffeine may be 1.52 or more in the coffee beverage. Further, the coffee beverage may comprise chlorogenic acid, and the chlorogenic acid content may be 0.01-0.1 mass%.
