ABSTRACT:
Apparatus for preparing a beverage, such as coffee, by extraction of soluble matter from a solid flavoring material into a liquid, in which a jug in the form of a thick walled vessel supported in a frame, acts as a cylinder, and a piston in the form of a capsule containing a flavoring material such as coffee, is arranged to rotate as it is moved axially within the cylinder. The capsule has liquid permeable membranes in axially opposed regions to allow liquid to be forced through the capsule to extract the flavor from the material within it without any of this material being able to escape. The capsule is detachable from the piston for refill or replacement.
