An assembly comprising a filter holder (2) and a coffee filter (4) which, in use, is filled with ground coffee for preparing a cup of coffee with a small-bubble foam layer (cream coffee). The bottom (6) of the filter holder (2) is provided with at least one outflow (14) opening. The coffee filter (4) is removably positioned in the filter holder (2) at some distance from the bottom (6) of the filter holder (2). The coffee filter (4) is provided with a paper filter via which the coffee extract can flow out of the coffee filter in the direction of the bottom (6). Located between the lower side of the coffee filter and the bottom (6) of the filter holder is a separation plate (16) provided with at least one jet opening (18). Located between the lower side of the separation plate and the bottom of the filter holder is an interspace (20). Through the presence of the separation plate (16) a pressure is built up so that coffee extract will be forced out of the jet openings (18) into the interspace (20) with great velocity. Thus, bubbles are formed in the interspace (20) which, when they are not too large, can flow out of the filter holder (2) into a cup. |
