1. A coffee dispenser for dispensing a single serving of coffee, the coffee dispenser comprising:
a first liquid line and a second liquid line, the first and second liquid lines joining at a junction;
a first port in liquid tight connection to the first liquid line up to the junction which forms a first liquid tight channel from the first port to the junction, the first port being engageable with a coffee concentrate container containing liquid coffee concentrate;
a first flow controller in fluid communication with the junction to control the flow of liquid coffee concentrate;
a water reservoir in liquid tight communication with the second liquid line up to the junction which forms a second liquid tight channel from the water reservoir to the junction, the water reservoir being capable of retaining water and delivering water to the second liquid line;
a second flow controller in fluid communication with the junction to control the flow of water; and
a main controller in operative communication with the first flow controller and the second flow controller, the main controller generating operational instructions for the first and second flow controllers to allow liquid coffee concentrate and water to flow to the junction and mix with each other to form the singe serving of coffee.
