An apparatus for brewing tea in accordance with an aspect of the invention includes a brew chamber that holds water. An infuser disposed in the chamber holds tea leaves and allows the water to contact the tea leaves. A heater heats the water in the brew chamber. A control sets a tea characteristic of the tea leaves. The tea characteristic can include one or both of tea format (loose or bagged) and tea type. The control can also set tea strength. A control circuit communicates with the heater. The control circuit controls power to the heater to heat the water to a steep temperature and then controls power to the heater to maintain the steep temperature for a steep time. The control circuit determines the steep temperature and the steep time based on the set tea characteristic or characteristics. It can further determine steep time based on the set tea strength. The tea leaves steep in the heated water until the expiration of the steep time to produce a brewed tea.

What is claimed is: 1. An apparatus for brewing tea, comprising: a brew chamber that holds water; an infuser disposed in the chamber that holds tea leaves and allows the water to contact the tea leaves, wherein the infuser includes a valve that opens when the water in the brew chamber reaches a predetermined temperature allowing heated water in the brew chamber to flow into the infuser; a heater that heats the water in the brew chamber; a control that sets a tea characteristic of the tea leaves; a control circuit in communication with the heater, wherein the control circuit controls power to the heater to heat the water to a steep temperature and then controls power to the heater to maintain the steep temperature for a steep time, the control circuit determining the steep temperature and the steep time based on the set tea characteristic and wherein the tea leaves steep in the heated water to produce a brewed tea; and wherein the predetermined temperature is lower than the steep temperature and the steep time begins when the water in the brew chamber reaches the steep temperature, wherein the control includes a user settable tea format control that is set to select whether the tea format is bagged or loose, the control circuit basing the steep time on the tea format set by the tea format control. 2. The apparatus of claim 1 wherein the tea characteristic includes a tea type, the control includes a tea type control and the control circuit determines the steep temperature based on the tea type set by the tea type control. 3. The apparatus of claim 2 wherein the tea type includes at least two of a black, oolong, green, white, or herbal tea. 4. The apparatus of claim 2 wherein the control includes a user settable tea strength control that is set to select a tea strength, the control circuit further basing the steep time on the tea strength set by the tea strength control. 5. The apparatus of claim 1 wherein the control further includes a user settable tea strength control that is set to select a tea strength, the control circuit further basing the steep time on the tea strength set by the tea strength control. 6. The apparatus of claim 1 further including a temperature sensor coupled to the control circuit that generates a temperature signal based on water temperature in the brew chamber. 7. The apparatus of claim 1 wherein control circuit includes a memory in which data is stored for steep times and steep temperatures for each settable tea characteristic, the control circuit determining the steep time and steep temperature from the data stored in the memory based on the set tea characteristic. 8. The apparatus of claim 2 wherein the control circuit includes a memory in which data for steep times and steep temperatures for each settable tea type is stored, the control circuit determining the steep time and steep temperature from the data stored in the memory based on the set tea type. 9. The apparatus of claim 2 wherein the control circuit includes a memory in which data for steep times and steep temperatures for each settable tea type in each settable tea format is stored, the control circuit determining the steep time and steep temperature from the data stored in the memory based on the set tea format and the set tea type. 10. The apparatus of claim 4 wherein the control circuit includes a memory in which data is stored for steep times and steep temperatures for each settable tea type at each settable tea strength, the control circuit determining the steep time and steep temperature from the data stored in the memory based on the set tea type and the set tea strength. 11. The apparatus of claim 5 wherein the control circuit includes a memory in which data is stored for steep times and steep temperatures for each settable tea format at each settable tea strength, the control circuit determining the steep time from the data stored in the memory based on the set tea format and the set tea strength. 12. An apparatus for brewing tea, comprising: a brew chamber that holds and heats water; an infuser disposed in the brew chamber that holds tea leaves, the infuser having a valve that opens when the water in the brew chamber reaches a predetermined temperature allowing heated water in the brew chamber to flow in to the infuser; a control circuit including a memory in which data for steep times and steep temperatures for different tea types in different tea formats and at different tea strengths is stored; a first user settable control coupled to the control circuit for setting whether the tea format is loose or bagged; a second user settable control coupled to the control circuit for setting the tea type; a third user settable control coupled to the control circuit for setting the tea strength; the control circuit determining a steep time and a steep temperature based on the tea format set by the first user settable control, the tea type set by the second user settable control and the tea strength set by the third user settable control; the control circuit heating water in the brew chamber to the steep temperature and maintaining the water in the brew chamber at the steep temperature until the expiration of the steep time, the steep time beginning when the water in the brew chamber reaches the steep temperature. 13. A method of brewing tea in a tea brewing apparatus having a brew chamber, a tea infuser disposed therein in which tea leaves are held, and a user settable control for setting a tea characteristic, comprising: storing data in a memory of the tea brewing apparatus; determining a steep time and a steep temperature based on the set tea characteristic; heating water in the brew chamber to the steep temperature and maintaining the water at the steep temperature until the steep time expires; triggering a temperature-dependent valve on the tea infuser at a predetermined temperature allowing heated water in the brew chamber to flow into the tea infuser to contact the tea leaves to begin steeping the tea leaves, the predetermined temperature being lower than the steep temperature; and steeping the tea leaves in the heated water for the steep time, wherein the tea characteristic includes a tea format and a tea type, the user settable control includes a user settable tea format control that is set to select whether the tea format is bagged or loose and a user settable control that is set to select the tea type, and determining the steep time and steep temperature includes determining the steep time and steep temperature from data stored in a memory of the tea brewing apparatus based on the set tea format and set tea type, the data including steep times and steep temperatures for each settable tea type in each settable tea format. 14. The method of claim 13 wherein the tea characteristic further includes a user settable tea strength control that is set to select a tea strength, and determining the steep time and steep temperature includes determining the steep time and steep temperature from data stored in a memory of the tea brewing apparatus based on the set tea format and set tea type and set tea strength, the data including steep times and steep temperatures for each settable tea type in each settable tea format at each settable tea strength. 15. The method of claim 13 wherein the tea format includes loose or bagged, and the tea type includes at least two of a black, oolong, green, white or herbal tea.
