A method is provided for the production of a unit type of package (1 ) of bush tea for use in a one use type of extraction or infusion process for the production of a bush tea beverage. Bush tea is compacted under a pressure of from 10 MPa to 500 MPa (0.7 to 33 tons per square inch) and most preferably from 50 to 100 MPa (3 to 7 tons per square inch). The compacted bush tea is further processed, as may be necessary, to provide individual units of compacted bush tea having a required shape, size and permeability. The bush tea may be compacted directly into individual units of compacted bush tea having a required shape and size or into a relatively large compacted body from which individual units of compacted bush tea are severed. The individual units are treated to maintain their integrity during subsequent packaging, transport and storage, such treatment commonly being enclosing each individual unit in a pouch or envelope (3) of permeable sheet material or of frangible impermeable sheet material.
