Abstract: Disclosed is a coffee extraction apparatus according to some embodiments of the present disclosure. The coffee extraction apparatus may include a user interface unit for receiving, from a user, an input to adjust a parameter for extracting coffee, wherein the user interface unit may include a first interface for receiving, from the user, an input of a first time period required to wet a puck contained in a portafilter of the coffee extraction apparatus using a fluid; a second interface for receiving, from the user, an input of a target pressure applied to the puck so as to extract coffee; and a third interface for receiving, from the user, an input of a second time period required to reach the target pressure.

Abstract: An espresso extraction device and an espresso extraction method are described that utilize a control unit that controls an operation of a valve unit or a pressure unit that adjusts pressure applied to an extraction unit of the device based on sensing data of a sensor unit in the extraction unit. A portafilter can be mounted on a head of the extraction unit, removing bubbles in the pressure unit by filling the pressure unit with a fluid and controlling the operation of the valve unit, removing bubbles in the extraction unit by filling the extraction unit with a fluid and controlling the operation of the valve unit, extracting espresso by exerting pressure to a fluid contained in the extraction unit by operating the pressure unit, receiving extraction pressure in the extraction unit via a sensor unit, and controlling the operation of the pressure unit on the basis of extraction pressure.
