The invention proposes a method for producing a beverage from an ingredient-containing capsule. The method comprising the following steps: inserting a sealed capsule into a capsule enclosure space of a beverage production device; enclosing the capsule by a relative displacement of at least two enclosing members which define the capsule enclosure space; opening an inlet face of the capsule and injecting a fluid under pressure into the capsule in order to open an outlet face of the capsule, the opening being assisted by the fluid pressure inside the capsule, wherein the capsule is provided at its outer surface with sealing material which is exposed to the fluid pressure in the capsule enclosure space; and after enclosing the capsule, having the fluid pressure reigning in the capsule enclosure space at least partially act on the sealing material, such that in turn the sealing material is pressed against one of the enclosing members thus constituting a flow resistance, the flow resistance being sufficient to guarantee a pressure build-up inside the capsule sufficient for the pressure-assisted opening of the outlet face of the capsule.
