US Patent 10575672 Cold coffee brewer

A cold coffee brewing device reduces the time required to produce cold brewed coffee. The cold brewer includes a container, preferably transparent, and an elongated brewing material holder suspended from a lid of the container. The brewing material holder is enclosed in a mesh to retain brewing material in the brewing material holder. In one embodiment, the mesh is a fine nylon mesh or a 75 micron opening nylon mesh. The lid includes a mechanism to rotate the brewing material holder. The container is filled with water and the brewing material holder is filled with brewing material. Movement of the brewing material submerged in water substantially reduces the time required for cold brewing.
