PROBLEM TO BE SOLVED: To prevent a stock liquid from fixing to a nozzle, or prevent a lump of the stock liquid from remaining on the bottom of a cup, and also, prevent a difference in the stock liquid concentration from being generated due to the difference in the location of a container. SOLUTION: The controller 20 of a beverage feeding device controls a syrup valve 8 and diluting liquid valves 10 and 12 while monitoring the signals of a syrup flow meter 7 and diluting liquid flow meters 9 and 11. Then, the syrup and the diluting liquids are discharged by specified amounts in a cup 14 from a nozzle 13, and they are mixed by a specified total diluting rate. The controller 20 opens the diluting liquid valves 10 and 12 prior to the syrup valve 8 in order to discharge the diluting liquids of specified prior discharging amounts first. Then, the controller 20 intermittently discharges the syrup, and continuously discharges the diluting liquids, and controls the opening/closing of respective valves 8, 10 and 12 in order to make the partial diluting rate meet the total diluting rate.
