A coffee brewing apparatus which can prepare either hot or cold coffee extract having a filter body (8) and two reservoirs (14a and 14b). The filter body 8 is a hollow cylinder with male threaded ends (10a and 10b). A mesh filter (12) is affixed to interior of the filter body (8). Two self-supporting reservoirs (14a and 14b) have female threads (16a and 16b) near their ends. Coffee grounds (18) and either hot or cold water (20) are added to one of the reservoirs. The apparatus is then assembled by joining the cylinder's male threaded ends (10a and 10b) to both reservoirs' female threaded ends. The assembled apparatus is then allowed to sit for a period of time, while coffee flavors are extracted into the water. The entire apparatus is then inverted, the mesh filter (12) removes the coffee grounds from the coffee extract (22), and the coffee extract is collected in the now lower reservoir (14a). The apparatus is disassembled for consumption of the extract, and is cleaned and reused.

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.

The present disclosure discloses a mocha pot combined device and method for using the same. By combining the pot body with the base, setting a temperature control device and a stirring device in the base, setting a detachable upper pot and lower pot in the pot body, and setting a filter between the upper pot and lower pot, water is stored in the lower pot and heated and then flows into the filter to mix with coffee powder, and it is then extracted to form coffee and flows into the upper pot for storage. The stirring device ensures that the water in the lower pot is evenly heated and reaches the required temperature quickly, and the temperature control device ensures precise control of the water temperature and heating time, thereby realizing automatic control of the coffee-making process, guaranteeing the taste of the coffee, and shortening the coffee brewing time.
