Abstract
The invention relates to a method of preparing beverages such as coffee, tea, soup or the like through extraction, in which the product to be extracted is accommodated in a chamber and is confined by a piston, whereafter liquid is supplied to the chamber via a liquid supply duct provided in the piston, the product to be extracted being extracted and the extract being discharged from the chamber. During the supply of liquid the flow rate is measured and, depending on these measurements, the supply of liquid is regulated in such a manner that for a specified desired total amount of extract the time of contact between the liquid and the product to be extracted has a predetermined desired duration. The invention further relates to an apparatus for carrying out the method, this apparatus comprising chambers of equal dimensions.
