Abstract: A sugar stick is provided to stir coffee until a desired sweetness is attained. The dispensing device for solid granular material is user adjusted from zero to a maximum by simply adjusting a movable cover, such as a sleeve or shutter to the indicated extent for the desired amount. The stirrer includes at least one dose separator disks attached to a central portion ending in an enlarged end section to be used as a handle, which fits into a perforated tube. The product granules, e.g. an artificial or natural sweetener, which are larger in size than the perforations, are housed in the spaces between the at least one separator disk. A transparent movable outer cover, such as a sleeve, encloses the perforations and seals them from contact with the liquid beverage. By pulling the movable outer cover up, the perforations corresponding to the desired level of sweetness dose can be easily exposed.
