A machine for preparing espresso coffee is proposed which has a brewing filter (10) which can be filled with ground coffee and which comprises a sieve (11' 12) with openings (13) of defined cross-sections in order to retain the ground coffee during brewing.

These devices are preferably constructed as needles (21) which are divided over their length into at least two stages of different cross-sections, such that the openings (13) in the sieve (11' 12) can be more or less closed depending on the insertion depth of the needles (21). …<IMAGE>… |
