Apparatus includes a water reservoir, a container for containing flavor-containing materials and a fluid delivery system for generating a plurality of pressure pulses, each including a water pulse and a steam pulse, and for delivering the pressure pulses through the flavor-containing materials. This extracts the useful compounds out of the flavor-containing materials under the pressure of the pressure pulses. The fluid delivery system includes a chamber, a heater in heat conducting relation with the chamber, a valve disposed between the reservoir and the chamber which opens to permit water to flow from the reservoir to the chamber when pressure in the chamber drops below a predetermined pressure. Method for making flavor-containing liquid with a plurality of pressure pulses includes generating and delivering a first pressure pulse in the form of a pressurized hot water pulse and a pulse of pressurized steam to and through the flavor-containing materials in a container. The flavor-containing materials is extracted by the pulse of pressurized hot water under the pressure of the first pressure pulse and are dried or potentially re-roasted by the pulse of pressurized hot steam. The next step is to generate and deliver a second similar pressure pulse, again, to and through the flavor-containing materials. The steps of generating and delivering pressure pulses to and through the flavor-containing materials can be repeated until a desired amount of flavor-containing liquid has been prepared.

1. Apparatus for extracting flavor-containing materials such as coffee, tea or herbs to make a flavor-containing liquid, comprising:a water reservoir for receiving a supply of water; a container for containing an amount of the flavor-containing materials and for allowing the extraction of the flavor-containing materials under pressure therein; and a fluid delivery system for generating a plurality of pressure pulses, each pressure pulse comprising a hot water pulse and a steam pulse, and for delivering the plurality of pressure pulses through the flavor-containing materials in the container, thereby extracting useful compounds out of the flavor-containing materials under the pressure of the pressure pulses, the fluid delivery system including a chamber, a heater in heat conducting relation with the chamber to heat water in the chamber and to produce steam, a conduit for delivering water from the reservoir to the chamber, a valve disposed in the conduit between the reservoir and the chamber which opens to permit water to flow from the reservoir to the chamber when pressure in the chamber drops below a predetermined pressure, and a fluid passage connecting the chamber and the container to allow the hot water and steam to be forced through the flavor-containing materials in said container by the pressure of the pressure pulse.
