Abstract:
A coffee machine comprising a coffee metering means, a brewing means having an essentially cylindrical housing and a support surface for receiving ground coffee transferred by the metering means into the brewing means and a means for applying water onto the ground coffee, characterized by a leveling means for purposefully guiding the water over the ground coffee in a non-uniform manner such that the ground coffee is distributed over the support surface in a layer having substantially uniform thickness, the leveling means contains a sieve arranged opposite to the support surface and comprising flow openings which have different sizes and/or are distributed in a non-uniform manner for producing a flow varying over the sieve, so that the open sieve surface formed by the sum of the flow cross-section of the flow opening is greater per unit area in a first central area of the sieve than in a second outer area of the sieve.
