14. The method of controlling the temperature of a brewed beverage in the brewed beverage dispenser as in claim 13 further comprising the step of:

preheating the surface of the brewed beverage dispenser which contacts brewed beverage disposed in the beverage dispenser prior to dispensing brewed beverage into the brewed beverage dispenser.

15. The method of controlling the temperature of a brewed beverage in the brewed beverage dispenser as in claim 14 further comprising the step of:

continuing to preheat the surface of the brewed beverage dispenser until at least a predetermined temperature is achieved for dispensing brewed beverage into the brewed beverage dispenser.

16. The method of controlling the temperature of a brewed beverage in the brewed beverage dispenser as in claim 15 further comprising the step of:

maintaining the heating of the brewed beverage dispenser for at least a portion of the time during which brewed beverage is dispensed into the brewed beverage dispenser.

17. The method of controlling the temperature of a brewed beverage in the brewed beverage dispenser as in claim 15 further comprising the steps of:

continuing to heat the brewed beverage dispenser throughout a period of time during which brewed beverage is dispensed into the brewed beverage dispenser; and
