A disposable cartridge comprises a substantially rigid envelope of plastics material which contains a dose of water-soluble granular, powdery or similar particulate matter adapted to produce a beverage by brewing with hot water. The envelope has an inlet endwall with one or more water inlet through holes close to, and radially inside a peripheral region thereof, the inlet end-wall being otherwise imperforate. The envelope has an opposite outlet endwall which has, within the envelope, a substantially axial tubular appendage which extends from the inner face of the outlet wall towards the inlet wall and which defines a beverage outlet conduit with an intake orifice near the inlet wall and an out-flow orifice in the outer face of the outlet wall.
