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.
