A sealed capsule contains a beverage ingredient in powder form, in particular, ground coffee. The capsule comprises a base body (4) and a foil member (5) tightly attached to the base body (4), the foil member (5) being made from a material allowing the production of a multitude of perforations in the foil member (5) when the foil member (5) is thrust, via the pressure caused by injecting a liquid or a liquid/gas mix into the capsule, against a relief plate of a beverage production machine, wherein the capsule is provided with a flow control porous member (80), the flow control porous member (80) being positioned between at least a portion of ingredients (3) and the foil member (5) . The flow control porous member provides a faster flow of the liquid extract through the capsule and significantly reduces the resurgence of non-soluble solids.
