A cool coffee infusing apparatus is disclosed having a liquid container, a ground coffee container, and an enclosure. The enclosure includes a pump, controls therefore, and receptacles for the containers. The liquid container is filled with cool water and the ground coffee container is filled with ground coffee. The pump circulates the water through the grounds until a desired level of infusion is achieved and coffee beverage is created. The coffee beverage is collected in the liquids container for pouring or for storage for later use.

A coffee brewing system and method that includes a brew chamber that holds a brew solution during a brew cycle and dispenses the brew solution; a water system that dispenses water into the brew chamber; a content sensing system that measures the brew solution contents added to the brew chamber; a temperature control system with a heating element and a temperature sensor; at least one recirculating processing loop with a particle monitor system, wherein the recirculating processing loop circulates brew solution extracted from the brew chamber; and a control system that is communicatively coupled to the content sensing system, the temperature control system and the particle monitor system during a brew cycle, wherein the control system controls a brew cycle based on a selected a specified taste profile.

A cool coffee infusing apparatus is disclosed having a liquid container, a ground coffee container, and a base. The base includes a pump, controls therefore, and receptacles for the containers. The liquid container is filled with cool water and the ground coffee container is filled with ground coffee. The pump circulates the water through the grounds until a desired level of infusion is achieved and coffee beverage is created. The coffee beverage is collected in the liquids container for pouring or for storage for later use.
