An apparatus and method useful for brewing a beverage. A brewing liquid, generally water, and in some cases brewing ingredients, are placed in a container having a bottom with openings that, due to surface tension of the liquid, do not allow the liquid to pass through the openings until the liquid approaches or reaches its boiling point. The liquid is heated to approach its boiling point by placing the apparatus in a microwave oven or by the use of an electrical resistance heater associated with the container. The brewed beverage is captured in a second, temporary container from which it may be consumed or served.

1. An apparatus for brewing a beverage, comprising:a reservoir for receiving a liquid, said reservoir having a hydrophobic surface, at least a portion of said surface being porous, with pores having characteristics such that surface tension of said liquid supports said liquid in said reservoir when
1. An apparatus for brewing a beverage, comprising:a reservoir for receiving a liquid, said reservoir having a hydrophobic surface, at least a portion of said surface being porous, with pores having characteristics such that surface tension of said liquid supports said liquid in said reservoir when said liquid is at an initial temperature, and allows said liquid to drain through said pores when said liquid is at a temperature which approaches or is at a boiling point of said liquid, wherein a height of said liquid in said reservoir is proportional to a radius of each pore to support said liquid until said temperature approaches or is at a boiling point of said liquid; and a brewing basket below the reservoir for receiving brewing ingredients and liquid from said reservoir, said brewing basket being configured to receive a containment filter for said brewing ingredients, said brewing basket having at least one opening through which a beverage brewed in said brewing basket can escape. 2. The apparatus of claim 1, further comprising a receiving vessel for receiving a beverage brewed in said brewing basket.3. The apparatus of claim 1, wherein said porous surface is at least mildly hydrophobic.4. The apparatus of claim 1, wherein said pores have a size in the range of approximately 10 to 200 microns.5. The apparatus of claim 1, wherein said porous surface is that of a portion of a lower wall of said brewing basket.6. The apparatus of claim 5, wherein said portion of said lower wall has a thickness of substantially 0.75 mm.7. The apparatus of claim 1, wherein said porous surface is integrally formed with other portions of said reservoir.8. The apparatus of claim 1, wherein said porous surface is imbedded within said reservoir in a liquid impervious manner.9. The apparatus of claim 1, wherein said porous surface comprises a hydrophobic porous medium embedded within another portion of said reservoir in a liquid impervious manner.10. The apparatus of claim 1, in combination with a heater for heating the brewing liquid.11. The apparatus as combined in claim 10, wherein said heater is one of an electrical resistance heater and a microwave oven.12. An apparatus for brewing a beverage, comprising:a reservoir for receiving a brewing liquid and brewing ingredients for brewing a beverage, said reservoir having a surface, at least a portion of said surface being porous, with pores having characteristics so that surface tension of said liquid supports said liquid in said reservoir when said liquid is at an initial temperature, and allows said liquid to drain through said pores when said liquid is at a temperature which approaches or is at a boiling point of said liquid, wherein a height of said liquid in said reservoir is directly proportional to a radius of each pore to support said liquid until said temperature approaches or is at a boiling point of said liquid. 13. The apparatus of claim 12, further comprising a storage vessel for receiving beverage brewed in said reservoir.14. A method for brewing a beverage, the method comprising:placing brewing ingredients in a brewing basket, said brewing basket being configured to receive a containment filter for said brewing ingredients, said brewing basket having at least one opening through which a beverage brewed in said brewing basket can escape; placing a reservoir for a brewing liquid over said brewing basket, said reservoir having a surface, at least a portion of said surface being porous with pores having characteristics so that surface tension of said liquid supports said liquid in said reservoir when said liquid is at an initial temperature, and allows said liquid to drain through said openings when said liquid approaches or reaches a boiling point of said liquid wherein a height of said brewing liquid in said reservoir is proportional to a radius of each pore to support said brewing liquid until said temperature approaches or is at a boiling point of said brewing liquid; placing the brewing liquid in said reservoir; heating the brewing liquid to a temperature approaching or at the boiling point of said brewing liquid to allow said brewing liquid to enter said brewing basket and mix with said brewing ingredients; and collecting brewed liquid in a receiving container. 15. The method of claim 14, wherein said portion of said container is comprised of a material which is at least mildly hydrophobic.16. The method of claim 14, wherein said heating is accomplished with microwave energy.17. The method of claim 14, wherein said heating is accomplished by placing said container in a microwave oven.18. A method for brewing a beverage, the method comprising:placing brewing ingredients in a brewing basket, the brewing basket being configured to receive a containment filter for the brewing ingredients, the brewing basket having at least one opening through which a beverage brewed in the brewing basket can escape; placing a reservoir for a brewing liquid over the brewing basket, the reservoir having a surface, at least a portion of the surface being porous with pores having characteristics so that surface tension of the liquid supports the liquid in the reservoir when the liquid is at an initial temperature, and allows the liquid to drain through the openings when the liquid approaches or reaches a boiling point of the liquid; placing the brewing liquid in the reservoir; heating the brewing liquid to a temperature approaching or at the boiling point of the liquid to allow the liquid to enter the brewing basket and mix with the brewing ingredients, wherein the heating is accomplished by using an electrical resistance heater associated with the reservoir; and collecting brewed liquid in a receiving container. 19. A method for brewing a beverage, the method comprising:placing brewing ingredients and a brewing liquid in a reservoir, said reservoir having a surface, at least a portion of said surface being porous, with pores having characteristics so that surface tension of said liquid supports said liquid in said reservoir when said liquid is at approximately room temperature, and allows said liquid to drain through said openings when said liquid approaches or reaches a boiling point of said liquid wherein a height of said brewing liquid in said reservoir is proportional to a radius of each pore to support said brewing liquid until said temperature approaches or is at a boiling point of said brewing liquid; heating the liquid to a temperature approaching its boiling point; and collecting brewed liquid in a receiving container.
