A method of producing flavor-releasing granules, comprising: (a) adding ethanol, together with a mixture of plurality of flavorant compounds, to an aqueous solution containing two or three cyclodextrin compounds selected from the group consisting of an α-cyclodextrin compound, a β-cyclodextrin compound and a γ-cyclodextrin compound at a total concentration of 1 to 10 % by weight, such that the mixture of plurality of flavorant compounds are present at a concentration of 3 to 10 % by weight in the aqueous solution and the ethanol is present at a concentration of 1 to 5 % by weight in the aqueous solution; and conducting stirring to include the flavorant compounds within the selected cyclodextrin compounds, thereby providing an aqueous coating solution containing the cyclodextrin mixture including the flavorant compounds; (b) maintaining hygroscopic core particles in a state of planetary motion, by placing hygroscopic core particles on a rotating disk of a centrifugal tumbling coating granulator comprising the rotating disk rotating horizontally, a cylindrical fixed wall provided spaced apart from the rotating disk and surrounding the rotating disk, and a lower wall closing a lower opening of the fixed wall; and driving the rotating disk to rotate and the same time feeding an air into a space provided between the rotating disk and the lower wall; and (c) intermittently spraying the aqueous coating solution onto the hygroscopic core particles in the state of planetary motion and conducting drying to form a flavor-releasing coat layer containing the cyclodextrin mixture including the flavorant compounds directly carried on respective surfaces of the hygroscopic core particles without a binder.
