Abstract
A method for preparing a hot beverage, in particular a coffee beverage or a tea beverage, with flavors being extracted from a flavor carrier, which is prepared from roasted coffee or dried tea, by means of water or steam having a plurality of steps: a predetermined quantity of the flavor carrier, in which the flavors are contained, is added to an extraction chamber which can be closed in a fluid-tight manner in a first step; water or steam for extracting flavors from the flavor carrier is added to the extraction chamber in a subsequent step; the extracted beverage flows out of the extraction chamber in a subsequent step; before the step of introducing water or steam into the extraction chamber, a step of introducing pressurized gas into the extraction chamber is executed. In the process, the internal pressure in the extraction chamber rises.

- An apparatus for preparing a hot beverage through extracting flavors from a flavor carrier comprising;
an extraction chamber, which can be sealed in a fluid-tight manner to the surroundings, a filter for filtering the beverage which is produced by the extraction, a compressed gas device adapted to supply compressed gas, wherein the apparatus is adapted to feed into the extraction chamber the flavor carriers followed by pressurized gas to build an internal pressure in the extraction chamber between 0.1 bar and 16 bar after the introduction of the pressurized gas, wherein the apparatus is further adapted to maintain the internal pressure in the extraction chamber for a predetermined waiting time before water or steam is additionally introduced into the extraction chamber, and wherein the hot beverage is a coffee beverage or a tea beverage. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 30, 31)
