Abstract: A technique allows display of a state in a process of extracting an extract from an ingredient. An extraction device includes a supply unit that supplies a liquid to an extraction vessel for extracting an extract from an ingredient, a control unit that controls the supply of the liquid by the supply unit, and a display unit that displays a state in the extraction vessel when the extract is extracted under the control of the control unit.

Abstract: A beverage producing apparatus capable of producing a plurality of types of beverages, includes: a display unit configured to display levels of a plurality of types of characteristics concerning a beverage of a type instructed by a user; and a control unit configured to control a producing operation of the beverage of the type selected by the user.

Abstract: An extracting method of extracting a beverage liquid from an extraction target includes a pressure reduction step of switching an interior of an extraction container in which the extraction target and a liquid are stored from a first air pressure to a second air pressure lower than the first air pressure, and an extraction step of extracting the beverage liquid from the extraction target. The first air pressure is an air pressure at which the liquid at a predetermined temperature does not boil, and the second air pressure is an air pressure at which the liquid that does not boil at the first air pressure boils. The switching from the first air pressure to the second air pressure is done by releasing the air pressure in the extraction container.
