Abstract
A tea brewer which automatically inlets a proportion of dilute water and brewing water to a siphon system to brew an extract for blending with the diluting water. The tea brewer includes a hot water tank having a volume of heated water therein and a fill tube for receiving a volume of cold water at the bottom of the hot water tank commensurate with the amount of hot water required to be siphoned therefrom to brew the tea leaves and make the extract. A vent for the hot water tank is provided to ensure that the full amount of hot water is siphoned. A cold water inlet line to the hot water tank is vented whereby to prevent cold water from being siphoned back along the cold water inlet line during the end of the cycle. The tea brewer further includes a line restrictor for creating a venturi effect along the dilute water inlet line. A needle valve is maintained at a slight back pressure in order to prevent starving the cold water inlet line carrying the displacement volume of cold water to the hot water tank.
