  • Coffee brewing method
    Patent number: 5980965
    Abstract: A method and system for brewing a desired volume of coffee at a selected brew time, in which a volume of water corresponding to the desired volume of coffee is heated and directed into contact with coffee grounds in a brewing chamber. Contact between at least a portion of the heated water and the coffee grounds is maintained for approximately the selected brew time to form brewed coffee. The brewing time, however, is substantially independent of the desired volume of coffee to be brewed and is controlled by control of the rate at which heated liquid flows into or out of the brewing chamber. At the expiration of the brewing time, brewed coffee is released through an opening in the brewing chamber and into an underlying receptacle.
