The invention claimed is: 1. A coffee maker, comprising: a housing; a coffee pot cavity located within the housing; a detector operable to detect the presence of a vessel in the coffee pot cavity, the detector located in the housing; an in-line water heater located within the housing and structured to couple to a water supply; a brewing area located within the housing to contain a supply of coffee grounds and to receive water from the in-line water heater; a pause and serve valve coupled to the brewing area; and a valve located between the water supply and the brewing area operative to stop a flow of water into the brewing area a predetermined amount of time after the detector detects that a vessel is no longer in the coffee pot cavity. 2. The coffee maker of claim 1, in which the coffee maker includes a water reservoir for storing water. 3. The coffee maker of claim 1, the detector comprising an infrared detector. 4. The coffee maker of claim 1 further comprising a controller operative to turn the water heater off a predetermined amount of time after the detector detects that a vessel is no longer in the coffee pot cavity. 5. The coffee maker of claim 1 wherein the coffee maker is an in-wall coffee maker. 6. The coffee maker of claim 1 wherein the coffee maker is affixed to a vertical surface. 7. The coffee maker of claim 3 wherein the detector further includes a lens adapted to filter environmental light interposed between the infrared sensor and the coffee pot cavity and operable to detect presence or absence of a coffee pot or mug in the cavity without contact therewith. 8. A coffee maker, comprising: a housing; a coffee pot cavity located within the housing; a detector operable to detect the presence of a vessel in the coffee pot cavity, the detector located in the housing; a reservoir located within the housing to store a predetermined amount of water from a water supply; a water heater located within the housing and thermally coupled to the reservoir; a first valve located between the water supply and the reservoir operative to stop a flow of water into the reservoir after a predetermined amount of water has entered the reservoir; a brewing area located within the housing to contain a supply of coffee grounds and to receive water from the reservoir; a pause and serve valve coupled to the brewing area; and a second valve located between the reservoir and the brewing area operative to stop a flow of water into the brewing area a predetermined amount of time after the detector detects that a vessel is no longer in the coffee pot cavity. 9. The coffee maker of claim 8, the detector comprising an infrared detector. 10. The coffee maker of claim 9 wherein the detector further includes a lens adapted to filter environmental light interposed between the infrared sensor and the coffee pot cavity and operable to detect presence or absence of a coffee pot or mug in the cavity without contact therewith. 11. A coffee maker, comprising: a housing; a coffee pot cavity located within the housing; a detector operable to detect the presence of a vessel in the coffee pot cavity, the detector located in the housing; a water heater located within the housing structured to receive a supply of water; a pressure switch located between the supply of water and the water heater; a brewing area located within the housing structured to contain a supply of coffee grounds and to receive water from the water heater; and a valve located between the water heater and the supply of water operative to stop a flow of water to the water heater a predetermined amount of time after the detector detects that a vessel is no longer in the coffee pot cavity. 12. The coffee maker of claim 11 further comprising a pause and serve valve coupled to the brewing area. 13. The coffee maker of claim 11 further comprising a controller operative to turn the water heater off a predetermined amount of time after the detector detects that a vessel is no longer in the coffee pot cavity. 14. The coffee maker of claim 11, the detector comprising an infrared detector. 15. The coffee maker of claim 14 wherein the detector further includes a lens adapted to filter environmental light interposed between the infrared sensor and the coffee pot cavity and operable to detect presence or absence of a coffee pot or mug in the cavity without contact therewith.
