The present invention refers to a capsule containing at least one aromatic substance for producing a beverage by means of its crossing by a pressurized fluid flow, and comprising at least one controlled opening element retained in a removable manner at least in one zone of the capsule facing the flow upstream and/or downstream. Said controlled opening element, by means of applying at least one certain actuation force exerted by a respective extraction device, may be displaced in at least linear or rotating fashion from an initial retaining position, that produces the airtight closure of the capsule, to at least one following position, thereby releasing at least one section of flow passageway of previously defined configuration and dimension in view of an optimized flow distribution inside said capsule. |
