Abstract: A coffee brewer, and, in particular, a single cup coffee brewer includes separate first and second members. The first member seats on a cup or similar receptacle and has a ground coffee receiving chamber formed therein. The second member is used to regulate the flow of hot water of similar fluid into the chamber. An aperture formed in the first member allows brewed coffee to flow from the chamber into the receptacle and regulates, by its size, the flow time of brewed coffee into the receptacle. A seal between the two members prevents the ground coffee from soaking in the brewing fluid.
