Abstract: A coffee maker and a control method therefor are disclosed. The disclosed coffee maker controls a dripper valve module to be closed in a first water supply section corresponding to a pre-wetting process so as to close an extraction hole, and controls the dripper valve module to be opened in a second water supply section corresponding to a coffee extraction process so as to open the extraction hole. Accordingly, a coffee drip process similar to a hand drip operation can be implemented.
