Abstract
The invention relates to an improved automated beverage making machine combining a traditional French Press of the plunger/strainer type with an improved automatic hot water dispensing machine, the dispensing machine having a housing, a water tank and automatic electric water heater. The dispensing machine is adapted to communicate with a French Press plunger/strainer extractor where the extractor also functions as a serving carafe for hot infused beverages such as coffee and tea. The invention also employs improved heating circulation and temperature sensing system which recirculates water until the water has reached a pre-selected desired temperature.
