A filter assembly for infusing an additive in a liquid. The filter assembly comprises an elongated filter bag that is rigidly reinforced along its vertical length and removably securable to the side of the vessel containing the liquid, to prevent flotation of the filter assembly and its contents. In an embodiment, the lower portion of the elongated filter bag is pre-filled with an additive and closed off to retain the additive in the lower portion. The filter assembly may be disposable. The invention further includes a method of dry-hopping beer using the disclosed filter assembly.

A combined container and stirring device which can be used with and resembles the shape of known infusion bags is disclosed. The combined container and stirring device comprises a body made of material that is resistant to liquids. The body comprises a lower body and an upper body. A filter bag surrounding a granular, powdered, or liquid product is provided. The filter bag is arranged within a cavity in the lower body. The upper body wraps around the lower body to form a compact shape when the device is in a folded state. The upper body extends upwardly from the lower body to form a handle when the device is in an expanded state.

A cartridge (1) for controlled brewing of loose-leaf tea in a cup, comprising an infusion chamber (2) for containing loose tea leaves (3) and infusing a liquid with substances from the tea leaves to brew tea. A chamber wall (20) impervious to the liquid defines the infusion chamber. In the chamber wall is a passage (21) between the infusion chamber and an exterior (5) thereof. The passage has an open state in which the infusion chamber is in liquid communication with the exterior, to transport the substances from the infusion chamber into liquid in the exterior during brewing tea. In a close state the infusion chamber inside is closed off from liquid in the exterior to stop a concentration of the substances in the liquid in the exterior from increasing. A manual control manually controllable by a human-being allows to bring the passage from the open state into the closed state.
