Method and apparatus for preparing hot beverages
First Claim
1. A method of preparing a hot beverage by brewing up a particulate substance extractable by means of water, the method comprising the steps of:
- providing a brewing chamber;
filling said brewing chamber with said particulate substance;
providing a supply of fresh brewing water;
heating said brewing water to a temperature above the normal boiling point of water while keeping said water in fluid matter of state;
feeding said heated water under pressure through said particulate substance received in said brewing chamber at a temperature above the normal boiling point of water and in fluid state of matter, thereby extracting said particulate substance to create a hot beverage;
collecting the thereby prepared hot beverage and cooling it to a temperature below the normal boiling point of water.

Abstract
The invention provides a method of preparing hot beverages by brewing up a particulate substance extractable by means of water. Thereby, the substance received in a brewing chamber is brewed up by brewing water that has a temperature above the normal boiling point of water, preferably 110° to 130° C., but still is in the fluid state of matter. The thus brewed beverage is cooled to a temperature below the normal boiling point of water before it flows to a beverage outlet. A significant advantage of this method is that the substance is much more efficiently extracted. For cooling the thus brewed beverage, preferably a heat exchanger is used through which fresh, not yet heated brewing water flows to thereby cool it.
