Zusammenfassung:The invention relates to a method for the preparation of a beverage in a beverage preparation machine (1) from a capsule (2) containing beverage ingredients by feeding water to the capsule through a first wall (6) of the capsule by a water pump (16) of the machine under the control of a control unit (21); the brewed beverage being extracted through a second wall (9) of the capsule; said second wall being preferably opened for extraction of the brewed beverage at least by the effect of pressure being built up inside the capsule as a result of the water being fed in the capsule; comprising: - feeding a first volume of water (V1) in the capsule containing beverage ingredients in dry state for prewetting the beverage ingredients in the capsule before beverage is extracted from the second wall (9) of the capsule ("prewetting"); - feeding a second volume of water (V2-V1) in the capsule to have beverage extracted from the second wall (9) of the capsule; wherein the feeding of the first volume is controlled at, at least one flow rate value that provides a continuous increase of the water pressure from the pump in a first ramp-up phase (30) of water pressure and, wherein the feeding of the second water volume is controlled to start immediately and without flow interruption after the feeding of the first water volume and is controlled to increase the water pressure until at least one pressure of extraction after a second ramp-up phase of pressure (31) which is controlled to be steeper than the first ramp-up phase (30) of pressure.
