An improved device for the preparation of individual coffee or tea beverages. A cylindrical, parallel walled container acts as both a brewing container and a drinking container. A plunger assembly is pushed down through the top of the container and effectively separates coffee grounds or the like from the brewed drink. A finely perforated disk having an upwardly oriented flange, is attached to the underside of a rigid perforated disk of the plunger assembly by means of a ribbed tab located at the center of the rigid perforated disk. Frictional attachment is made by inserting the ribbed tab of the rigid, perforated disk into the slot of the finely perforated disk. When removing the plunger assembly, the finely perforated disk detaches from the plunger assembly and remains in the bottom portion of the container thereby trapping the coffee grounds or the like between the finely perforated disk and the bottom of the container. The remaining brewed beverage can be drunk by a person in a similar way to a normal coffee mug. Upon completion of the beverage, the finely perforated disk can be removed and reattached to the plunger assembly for reuse.
