An improved cork closure for beverage and wine bottles having a recess on the outer face of the closure. The recess is designed to facilitate the extraction process by providing central constraint on the position of the corkscrew on the face of the closure and to guide the corkscrew along the axis of the closure. This recess does not interfere with any other type of extraction device.

1. In combination with a wine bottle, said bottle having an opening and an extractable closure for said opening, said closure comprising: a solid cylindrical body having an outer face and an inner face, said cylindrical body comprising a length of said closure from said outer face to said inner face and comprising a single compressible material disposed in said bottle opening; anda corkscrew guide disposed in said outer face of said closure, said corkscrew guide comprising a shallow annular recess substantially centered on the axis of said cylindrical body and said recess having two non-central perimeter walls, said recess to accept a tip of a corkscrew and said walls providing constraint at any point along the perimeter of said recess, andwherein said recess is adapted to a helix of the corkscrew to promote a central position of the corkscrew during use. 2. In combination with a wine bottle, said bottle having an opening and an extractable closure for said opening, said closure comprising: a solid cylindrical body having an outer face and an inner face, said cylindrical body comprising a length of said closure from said outer face to said inner face and comprising a single compressible material disposed in said bottle opening; anda corkscrew guide disposed in said outer face of said closure, said corkscrew guide comprising a cylindrical bore substantially centered on the axis of said cylindrical body, said bore to accept and constrain the corkscrew helix, said bore penetrating less than half the length of the closure and said bore penetrating more than one full turn of the corkscrew helix; andwherein said bore is adapted to a helix of the corkscrew to promote guidance along the axis of the closure and a central position of the corkscrew during use. 3. In combination with a wine bottle, said bottle having an opening and an extractable closure for said opening, said closure comprising: a solid cylindrical body having an outer face and an inner face, said cylindrical body comprising a length of said closure from said outer face to said inner face and comprising a single compressible material disposed in said bottle opening; anda corkscrew guide disposed in said outer face of said closure, said corkscrew guide comprising multiple shallow recesses, said recesses to accept a tip of a corkscrew and each recess having at least one non-central wall to constrain said tip of said corkscrew; andwherein said recesses are adapted to a helix of the corkscrew to promote a central position of the corkscrew during use. 4. The closure of claim 3 wherein said multiple recesses comprise a plurality of co-central annular rings of different diameters assembled according to their diameters. 5. The closure of claim 3 wherein said multiple recesses comprise a plurality of co-central cylindrical recesses of various diameters disposed in said outer face according to diameter, wherein the opening of a smaller recess opens into the bottom of the next larger recess and the largest recess opens on the outer face of the closure. 6. In combination with a wine bottle, said bottle having an opening and an extractable closure for said opening, said closure comprising: a cylindrical body having an outer face and an inner face, said cylindrical body comprising a length of said closure from said outer face to said inner face and comprising a compressible material and disposed in said bottle opening; anda corkscrew guide disposed in said outer face of said closure, said corkscrew guide comprising a recess to accept a tip of a corkscrew and having at least one wall to constrain said tip of said corkscrew and to promote positioning of the corkscrew as the corkscrew penetrates said closure;wherein said recess is adapted to a helix of the corkscrew to promote a central position of the corkscrew during use of the corkscrew; andthe recess is comprised of multiple intersecting annular recesses not centered on said outer face. 7. In combination with a wine bottle, said bottle having an opening and an extractable closure for said opening, said closure comprising: a cylindrical body having an outer face and an inner face, said cylindrical body comprising a length of said closure from said outer face to said inner face and comprising a compressible material and disposed in said bottle opening; anda corkscrew guide disposed in said outer face of said closure, said corkscrew guide comprising one or more shallow non-central holes, said holes to accept a tip of a corkscrew, and at least one wall of said hole to constrain said tip of said corkscrew as the corkscrew penetrates said closure; andwherein said one or more holes are adapted to a helix of the corkscrew to promote a central position of the corkscrew during use and extraction of the closure. 8. In combination with a wine bottle, said bottle having an opening and an extractable closure for said opening, said closure comprising: a cylindrical body having an outer face and an inner face, said cylindrical body comprising a length of said closure from said outer face to said inner face and comprising a single compressible material and disposed in said bottle opening; anda corkscrew guide disposed in said outer face of said closure, said corkscrew guide comprising one or more shallow linear recesses, said recesses to accept a tip of a corkscrew and at least one wall to constrain said tip of said corkscrew as the corkscrew penetrates said closure; andwherein said recesses are adapted to a helix of the corkscrew to promote a central position of the corkscrew during use and extraction of the closure. 9. In combination with a wine bottle, said bottle having an opening and an extractable closure for said opening, said closure comprising: a cylindrical body having an outer face and an inner face, said cylindrical body comprising a length of said closure from said outer face to said inner face and comprising a single compressible material and disposed in said bottle opening; anda corkscrew guide disposed in said outer face of said closure, said corkscrew guide comprising a shallow cylindrical recess substantially centered on the axis of said cylindrical body, said recess having a non-central perimeter wall to structurally constrain and position the tip of a corkscrew,and wherein the diameter of said recess is adapted to the helix of the corkscrew to promote a central position of the corkscrew during use and extraction of the closure.
