1. In a brewing apparatus, the improvements comprising: a brew holder including a rim portion and a cup portion having an inner surface extending downwardly from said rim portion; a liner adapted to form a liquid impervious container, said liner being made of a flexible medium operable to be converter from a relatively flat condition in which said container has an internal volume of negligible proportions to an expand condition in which said container has an internal volume approximating that of said cup portion; said liner being operable in said expanded condition to be supported by said rim portion of said holder and to depend from said rim portion within said cup portion, said liner having an outer surface operable to contact the inner surface of said cup portion in response to the placement of liquid into said supported liner. 2. A brewing apparatus according to claim 1 wherein said liner is made of a plastic film. 3. A brewing apparatus according to claim 2 wherein said plastic film is capable of withstanding a temperature of at least 212 degrees Fahrenheit. 4. A brewing apparatus according to claim 1 wherein said liner in said flat condition has a lower depending portion, a median lip portion and an upper overlay portion, said liner in said expanded condition being adapted to be supported by said holder with said lowr depending portion within said cup portion, with said median lip portion engaging said rim portion, and with said upper overlay portion positioned outwardly from the interior of said cup portion. 5. A brewing apparatus according to claim 1 wherein said liner in said flat condition has a lower depending portion, a median lip portion and an upper overlay portion, said liner in said expanded condition being adapted to be supported by said holder with the exterior surface of said overlay portion exterior of said holder and remote from contact with liquid contained in said supported liner. 6. A brewing apparatus according to claim 5 wherein said holder has an array of projections externally of said cup portion, said overlay portion of said liner is provided with an array of aperatures corresponding to said array of projections, said liner in said expanded condition being adapted to be supported by said holder with said array of aperatures engaged by said array of projections. 7. A brewing apparaus according to claim 6 wherein the engagement of said arrays of aperatures and projections is such as to produce a smooth fit between the said rim portion of said holder and said lip portion of said liner. 8. A brewing apparatus according to claim 5 wherein a cutout portion is provided in the upper overlay portion of said liner. 9. A brewing apparatus according to claim 1 further comprising means for positioning said liner with respect to said holder so as to prevent said liner in said expanded condition from being displaced from support by said rim portion of said holder in response to the introduction of liquid into said expanded condition liner. 10. A brewing apparatus according to claim 9 wherein said means for positioning said liner includes a brew basket. 11. A brew apparatus according to claim 11 further comprising a brew basket having a peripheral portion adapted to engage said rim portion of said holder in overlying relation with said liner supported by said rim portion. 12. A brewing apparatus according to claim 11 wherein said liner includes an upper overlay portion adapted to be positioned outwardly of the interior of said cup portion and outwardly of said peripheral portion of said brew basket. 13. A brewing apparatus according to claim 11 wherein said brew basket is isolated by said liner from direct contact with said rim and cup portions of said holder. 14. A brewing apparatus according to claim 11 wherein said holder includes an arm engageable with said brew basket for urging said peripheral portion thereof into compressive engagement with said rim portion and said liner supported thereby. 15. A brewing apparatus according to claim 14 wherein said holder is provided with a handle member radially exterior of said cup portion, said handle member having a top portion, a cylindrical recess formed in said top portion, and said arm includes a shank portion rotatably and telescopingly engaging said cylindrical recess. 16. A brewing apparatus according to claim 15, wherein, said arm includes a distributor portion, said brew basket having a top engageable by said distributor portion. 17. A brewing apparatus according to claim 16 further comprising detent means provided between said shank portion and said cylindrical recess for retaining said distributor portion in compressive engagement with said brew basket top. 18. A brewing apparatus according to claim 11 wherein said brew basket comprises a fiber filter portion and a plastic material bonded to said filter portion 19. A brewing apparatus according to claim 11 wherein said brew basket has a substantially flat planar configuration prior to engagement with said rim portion of said holder, said brew basket in said planar configuration being manually modifiable to a three-dimensional shape having a top portion spaced from said peripheral portion. 20. A brewing apparatus according to claim 19 wherein the sides of said three-dimensional shape substantially conform to a frustro-conical section. 21. In a brewing apparatus, the improvements comprising: a brew holder including a rim portion and a cup portion having an inner surface extending downwardly from said rim portion; a liquid impervious liner adapted to be positioned within said cup portion of said brew holder and to form a disposable brew container, said liner having a portion adapted to overlay said rim portion of said brew holder and having an outer surface operable to contact the inner surface of said cup portion; and a brew basket positionable on said rim portion of said brew holder in engagement with said overlay portion of said liner whereby said liner is adapted to isolate said brew holder from contact by a brewed liquid flowing from said brew basket. 22. A brewing apparatus according to claim 21 wherein said brew basket includes a bottom portion, a top portion, and a frustroconically shaped side wall joining said bottom and top portions; said side wall having an interior surface, an exterior surface, and ribs; said ribs forming alternating ridges and valleys arranged such that each ridge on one of said surfaces is opposed by a valley on the other of said surfaces. 23. A brewing apparatus according to claim 22 wherein said ribs extend substantially normal to said top and bottom portions; and said bottom portion is formed by a wall having an inner surface, an outer surface and raised and lowered portions arranged in a symetrical pattern within the perimetr of said bottom portion, said bottom wall being provided with at least one aperture for the passage of brew therethrough. 24. A brewing apparatus according to claim 23, wherein said brew basket further includes an integral outer wall extending from said top portion in diverging relation with said exterior surface of said side wall to a peripheral portion adapted to engage said rim portion of said holder in overlying relation with said overlay portion of said liner, said outer wall being provided with ribs corresponding to the said ribs on said side wall. 25. In a brewing apparatus, a brew basket having a bottom portion, a top portion, a frustroconically shaped side wall joining said bottom and top portions, said side wall having an interior surface and an exterior surface, and ribs on said side wall, said ribs extending substantially normal to said bottom and top portions and forming alternating ridges and valleys on said interior and exterior surfaces, each ridge on one of said surfaces being opposed by a valley on the other of said surfaces. 26. A brewing apparatus according to claim wherein said bottom portion is formed by a wall having an inner surface, an outer surface and raised and lowered portions arranged in a symmetrical pattern within the perimeter of said bottom portion, said bottom wall being provided with at least one aperture for the passage of brew therethrough. 27.
