ABSTRACT:
A siphon of preheated water to a filter basket is initiated by an inpour of cold water to a buoyant tank floating in a holding tank on the preheated water. The cold water addition causes the buoyant tank to sink thus raising the level of the preheated water to start a siphon. The cold water is thereafter metered to the holding tank and preheated preparatory to initiating another brew cycle.
