PROBLEM TO BE SOLVED: To provide a carbonater system for a beverage feeder capable of maintaining the desired gaseous volume of carbonated water and further increasing the gaseous volume even in a beverage feed waiting period. SOLUTION: A carbonater 4 is connected to a water feed pipe 2 via a first three-way valve 1 and a pump 3, a carbonated water feed port 6 is connected to the carbonater 4 via a second three-way valve 5, and the first three-way valve 1 is connected to the second three-way valve 5. In the waiting mode, a circulation circuit through the first three-way valve 1, the pump 3, the carbonater 4 and the second three-way valve 5 is formed. In the carbonated water feeding mode, the three-way valves 1 and 5 are changed over, and a feed passage from the feed water pipe 2 to the carbonated water feed port 6 through the first three-way valve 1, the pump 3, the carbonater 4, and the second three-way valve 5 is formed.
