A brewing material holder includes a spinning assembly for uniformly dispersing water into brewing material. The spinning assembly may be attached to a removable holder lid or reside in the base of the holder. When water is pumped into the holder, the flow of water is sprayed into brewing material contained in the brewing chamber. On one embodiment, water is pumped into the brewing material holder, and the flow of water causes the spinning assembly to spin by the water flowing past gears or a propeller, or by tangential jets on the spinning member. In another embodiment, the coffee maker includes a rotating shaft engaging the brewing material holder to cause the spinning assembly to spin, or may include stator winding creating a rotating magnetic field in the brewing chamber to cause the spinning assembly to spin.
