Exemplary embodiments are generally directed to beverage chillers for chilling a hot beverage so that the hot beverage can be served as a chilled beverage in real time on demand fashion. The beverage chillers include a beverage collection section, a heat exchanger section, and a dispensing section fluidically connected relative to each other. The beverage collection section receives a beverage in a hot state. The heat exchanger section chills the beverage from the hot state to a predetermined chilled temperature. The dispensing section dispenses the beverage at or near the predetermined chilled temperature. Exemplary embodiments are also directed to methods and systems for chilling a hot beverage in real time on demand fashion.
